Can you use the same Lens cleaner that you use for DVD players for Blu-Ray Players Too?

Bright

I've seen one that says it works with some kind of wind system, but it seems like they are trying to just get more money. Does anyone know for sure if you can use the same "DVD with a brush on the bottom" for Blu-Ray players, too?
Could you use a regular DVD lens cleaner to clean a PS3?

Answer
No. Do not use a brush cleaner on a Blu-ray player or a PS3.

The lens is much more prone to scratching because of the shorter wavelength of light and smaller spot size used by Blu-ray.

You should only clean the lens if you have a problem. Often a can of compressed air will work just as well.

Blu-Ray player or PS3?

Dean Winch

I'm getting a new TV, and I have the choice of one of those, but I can decide.

I am a gamer so, a PS3 will just complete my collection of consoles. :P

Answer
I recently completed my collection of consoles to go with my 55" Samsung LED. I couldn't be more satisfied with the ps3. I have gone through 3 different blu Ray players, and re PS3 does the best job of loading blu rays quickly as well as upscaling DVD's. It has built In wifi, and in integrated web browser. The only Blu Ray player I've seen match the PS3 is the Oppo, and that runs for $700.

Edit: my reciever outputs 120 watt per speaker and my sub is a powered 200 watt downfiring.

My reciever is a pioneer vsx1019 ah-k look into it because it has auto speaker caliberation :) a nice feature that saves you the trouble of hiring a professional each time I rearrange my speakers/ add new furniture (yes it's THAT sensitive)

That 7 core Cell processor handles blu Ray 2.0 like water and outputs clean, crisp surround sound 5.1 OR 7.1 - most blu Ray players only support 5.1

furthermore, you can hook up a wireless mouse or Bluetooth mouse and a wireless or bt keyboard.
Go with the PS3 and you will NOT be disappointed. I have a 7.1 reciever with 120 watt, and 7 harman Kardon speakers plus 1 subwoofer the size of a coffee table. Buy the ps3 and you won't be disappointed :)

Help! Blu ray player skipping?

Tonya

So I bought my mom a sony blu ray player last december and now it wants to skip on sertain disks. It first started skipping when we bought 2 blu ray discs avatar collecters addition and the host. So then we bought a cleaning disc for it and that jus made the skipping worse. So then we tried a movie (the sand pebbles) that we already had and it to was a blu ray disk and it played fine at first then when it went to the main screen and after we pressed play there was no picture only sound. So then we went to my philips player and I put the host in and it played fine. And while I was doing that my mom watched the shinning and it played fine. So the next day I brought mine out of my room and replaced it with the sony and we watched avatar on it and it played fine. But then we played the sand pebbles on my philips player at it did the same thing no picture only sound. It seems the sony player is being picky on which movies it wants to play. But what I can figure out is all the blu ray discs that skipped on the sony player worked fine on the philips player. But the only movie that still messes up on either player is the sand pebbles. What is going on with the player its never done this before unless of course if the discs had scratches. But the blu ray discs resist scratching but just in case I looked on the discs that were skipping and there were no marks on the discs. I also want to know if I messed it up with the cleaner disc? And it would be ashame that the player mess up when playing only after 2 years. Do I need a new player? or could there be something wrong with the HDMI cord? Although that wouldn't make sence because I'm using the same wire on my philips player that was used on the sony player. My philips player is older, mine is about 3 years old if not more. And it plays perfect I havnt had any problems with it what so ever. So I don't understand why mine being older is still going strong. Also I got the sony player off of amazon if that helps. Please help.

Answer
I learned a whole lot at one time from a best buy tech in my home state about this format, you needed to check the packaging on the pack you bought as to if you had the 2D disc in there, or the 3D disc in there at the time of playback.

these discs are encoded with intricate playback data which is very sensitive and much more so than a dvd because they use a blue laser hence the term blu ray. you need to be careful when cleaning these discs.

im assuming the first two were SD disc (2D disc combo packs) films with the single blu only. avatar you bought in the combo pack which i assume you did, this film was in native 3D when filmed, a 2D was created for those who could not tolerate the sterography the 3D entails.

The Phillips Blu-Ray player is intended for 2D playback, you needed to have watched the particular disc you inserted into the player because of the 3D disc to any of the movies you listed will have one of many possible outcomes: 1. error message saying you can't view it 2. refusal to play 3. being told you need the following equipment listed on the back of the combo pack: 1. 3D TV 2. active/passive shutter glasses (passive is better as it doesn't hurt) 3. PS3 4. HDMI cable at hi-speed

your discs on both of these players could be scratched, the sony you could of had as a 3D player (i assume if it is a dual mode model which plays in 2D mode if needed) could have internal damage to it.

if both are 3D/2D players they both need to be serviced and or replaced by a certified tech trained in the blu-ray format

if you are having picture/audio playback problems as well as presentation setup, you may need to buy all of it again as you are operating on defective equipment between both players.

it is time for a new player as the phillips is 2-3 years older if not more, replace the cable also. the older player is still pumping, but don't expect the strong performance for very long afterwords.

if the sony is picking and choosing what it wants, replace it as its fully defective. you will not get much performance out of it.

the sand pebbles needs to be replaced also, the disc is defective. check the packaging as to how you bought it. single disc, easy shot replacement. multi-combo pack set if it was purchased like that, you will need to throw money down on the combo again.

if they were with no marks, it is defection in the discs. you messed it up with the cleaner disc, the player has very sensitive parts which must be well maintained. the manufacturer could also have screwed up when designing the player. it could be a defective unit, that warrants whole unit replacement.

i would take your concerns in front of a tech, they are good at solving your problems. i am looking to be a first timer fairly soon.

you have a 2D setup from the looks of the question, well i would say the 2D units are harder to maintain than stereoscopic 3D units which can play both. 2D can also do both itself and 3D as well, only certain 3D discs will go past the gate though as a signal will be emitted to the player to tell it what your running, if it is a full 1080i HD 3D signal with the right equipment and parts it will accept playback, if 1080i full HD, yes and no.

on a 2D setup if you have one of the 4 parts but not the other 3 there are exceptions like piranha 3D, this will downconvert itself to create a 2D signal in 2D space on a 2D setup. the message displayed is this disc will only play in 2D without special hardware, to watch in blu-ray 3D you need a 3D tv, active shutter glasses/passive shutter glasses, and a PS3 with the latest firmware update. the only one i know of that goes past the gate.

that blu-ray 3D is an exception to this rule that only certain blu-ray 3D discs go past the gate, and again only anaglyph can go past the gate on a 2D tv. frame sequential (tech in the newer discs designed to do stereoscopic 3D) requires spending $1000+ on all the equipment.

my advice to you in the future with these is watch your display setups, watch the disc you are inserting when you are watching (these are specifically on the packages in the combos especially), watch for 2D or 3D when inserting it into the player (some 3D discs can mess up player operations as well if on a 2D setup, others can go past the gate if they downconvert to 2D like piranha 3D), and lastly be very careful with the unit and its parts, one false move and it could affect the players proper operation.

with the combos if any or all of the discs attain damage, you will need to buy any or all of the discs again if they fail on playback. BD 3D+BD 2D+DVD+DC+UV or any combination all have sensitive encodes that if damaged can affect unit operations if you're not careful.

i hope this helps you out.

Where is the remote sensor on a Samsung 55D7000 LED tv?

blu ray player cleaner image

Camm

Today my tv decided that it wasn't going to be turned on by the remote control. I use the remote for my Samsung HT D5300 blu-ray home theatre, the original remote is currently unusable. I'm wondering where the sensor for the remote is on the tv, perhaps it needs to be cleaned. The remote itself still works with the blu-ray player.

Answer
Our Samsung sensor is on the front next to the t.v. power button.
No matter the t.v. the sensor will be on the front

What size battery back-ups would I need for my electronic equipment?

PA Fish Ma

Hello, I have an Integra amplifier, a blu ray dvd player, cable box and an Epson 1080p pro-cinema projector. I want to put my equipment on two battery back ups. I just want to be able to run everything long enough to have time to shut it down safely if the power goes out. I have a generator and this is the second reason why I want the battery back ups. If the power goes out and I have to run my generator I want to use the back ups to keep the power clean to my equipment. The projector is plugged into the ceiling so I would like to put it on it's own back up. What kind of battery back up would I need to run it for lets say 5 minutes without power? I want to put the Amp, DVD player and cable box on another back up. What kind of battery back up would I need to run it for the same? I am sure I would not have the volume all the way up during a power outage and I can keep it down low during generator use. My generator is plugged into my breaker box to run the entire house. The Integra specs are AV Receiver DTR-30.4, 8 speaker, Rated output power all channels 100 watts minimum continuous power per channel, 8 ohm loads, 2 channels driven from 20 Hz to 20 kHz, with a maximum total harmonic distortion of 0.08% (FTC). 7 ch x 160 W at 6 ohms, 1 kHz, 1 ch driven of 1% (IEC) Maximum effective output power 7ch x 175 W at 6 ohms, 1 kHz, 1 ch driven (JETTA) Dynamic Power IEC60268 short term maximum output power 240 W (3 ohm Front), 210 W (4 ohm Front), 120 W (8 ohm Front). Thanks in advance for helping me.
One Battery Back up is for The Amp, DVD player and Cable box. The other Battery Back up is for the Epson 1080p pro-cinema projector alone.

Answer
The specifications you gave were for the audio portions of the equipment and there is no direct correlation between those values and actual power drawn.

Each piece of equipment will have a plate or label indicating the power requirements of that device. Realize that they are maximum power ratings and not necessarily the actual power they draw in normal use. (I doubt you are cranking your amp at 7 x 175 watts in your living room)

Anyway, once you have those ratings, then us them to determine the size UPS you need.

I'll assume you're in the US and your power is 120 volts.
Let's say your DVD player says it takes 2 Amps. (that's high, but I'm using easy numbers)

That's 240 watts since power equals voltage times current.
It's likely that your DVD player is actually rated in Watts, and that's even easier since they did the math for you. The DVD player will actually be closer to 8 Watt, so you know.

I'll make up a number and say all your equipment power added up is 500 Watts.
You will need a UPS rated to handle that, so let's say you get a 800VA UPS.
(for simplicity and practicality, 1 VA = .7 Watt, even though it's not... close enough. This can't become and engineering lesson on power factor.)

So, now you know you need a 800VA UPS, but that's just the maximum amount of power it can provide, it doesn't tell you for how long. Power over time is energy, so now you want to know the energy capacity of the UPS since you know it's big enough to handle the load.
Remember the actual load is likely smaller than the maximum possible load in things like amplifiers. TVs pretty much draw constant power, as do DVD players when they're running, etc.

Unfortunately, manufacturers don't often come right out and say what you want to know and that the Wh rating. Watt-Hours are how many Watts can be provided in one hour.
If you found an 800Wh UPS, it could provide 400Watts for two hours. This is a large amount of energy for a battery and that battery would weigh about 100 lbs. +
That same UPS could provide enough energy to run the 8W DVD player for 100 hours, or close to 4 days.

Here's an example of how the manufacturer tells you how long you can run at particular power levels:
https://www.apc.com/resource/include/techspec_index.cfm?base_sku=BR1300LCD
According to their chart... their 1300VA/780W UPS can supply 300 Watts for just over 20 minutes.

Or matrix like this where you select the wattage on the left and it calculates the run time for you.
http://www.apc.com/products/family/index.cfm?id=29&tab=models
Select 400W and see how many choices are eliminated. They're saying they can't supply 400W for any duration... they are undersized for the load.



You might find a 1500VA UPS that does half that because the 1500 rating is just for maximum load, not for how long it can supply that load. It's a numbers game and they're banking on the fact that the stupid consumers will just buy a 1500VA over a 1300VA since it's "bigger". It could actually have 1/2 the energy of the 1300VA... you can't know unless they tell you.

All things held equal (battery size in the UPS, mostly)... the more power you draw, the shorter the run time. And it is NOT linear, as you can see by the run-time curve from APC.

It's a lot of information... but if you want to properly size your UPS, you can't just guess.

Personally, I don't buy integrated units since you're stuck using their batteries and are limited to their energy capacities.

Is there a difference between upconverted DVD and Blu Ray?

hanzo7

My blu ray player says it can upconvert DVD to 1080p for out of this world quality. So does that mean it's going to be like I'm watching blu ray?

Is there a difference in picture quality between upconverted DVD and Blu Ray?

Answer
Yes there is.
Upconvering is "guessing" the pixels
BD has the real pixels, so it is sharper and cleaner.

What does an upconvert dvd player convert the display too?

blu ray player cleaner image

diggittey

I have a 720p hd tv-but also have a blu ray dvd player, and I know they play at 1080i--just wondering if watching blu ray dvd on a 720p is redundant in that an upconvert can give the same image. Just curious???? I plan on getting a 1080--just waiting to see the 120hz's to come down. thanks.

Answer
There is no 'stretching' involved.

It's not making it true HD

What they are doing is basically tons and tons of math. The signal on a DVD is 480 pixels by 720. So a chip in these players is taking that and making it into 1080x1920 i or p or 720p. It comes out as that new higher res signal, but it can't create more detail that what the original contained. It's just a trick, and it's generally better done on a DVD player than in the TV.

It does help things look cleaner and less jagged since you can notice such things more easily on a huge HDTV. But understand, no upconverting player, no matter how expensive or how advanced the chipset, will give you more detail than a true high def, high bit rate source like a blu ray disc.

Not all 720p HDTV have the same res, as there are three different pixel counts depening on the display tech. They are 1024x768, 1280x720 and 768x1365 (give or take) the pixel count runs from about 750k to about 1 million, that's three to 4 times higher pixel count than regular DVD.

So even though you don't have full HD, you'll still get the benefit of the extra def that blu ray offers. The player can be set to 720p or the TV will down convert a 1080i signal (if you set the player to that) note, not all 720p sets can handle or convert a 1080p signal. Not to worry just set the player to another resolution.

Hope this helps, go out and get a blu ray on black friday! Wal mart will have one for 128 rocks, that is if they have any left.

How do I pick out the best HDMI cables for my new 1080p LCD TV?

JayRust

I'll need 1 to run from my dvr to the tv and I'll be hooking some devices up like a blu-ray player, game consoles, etc. Thank you!

Answer
The donkey above who spent 200 on cables is a fool. Really all you need is a $3 cable from monoprice.com. I have a 46" Samsung LCD 1080p and the picture is crisp and clean. The only reason you would want to spend more is if you are spanning a 25' gap or something of that sort. If you are just getting a 3' or 6' cable, then a $3 one will do just as well as a $40.
