Re: Screen goes White

Yes and this sounds like they might of made a little mistake, but to you it's Major. It seems you need what is called a Flex Converter. If your set is V500 the part # is CS00771, and if it's V500A then part # is CS00772 for more info on this you can visit

How to fix in center of the screen a white sprider image affect?

you will need a new one of these sony optical block 1-788-303-21 kdf-e50a10. when it over heats the picture will go strange also just sometimes there is a build up of dust blocking the light in the chamber in the optical block you may be able to clean this out but any scratches you make on the glass will be seen when the tv is on. also there is a lot of resting to do when you put back you have to re-aline the output to the screen size using the adjuster.

My LTV-32w6 westinghouse powers on & has sound but displays black screen with very faint colored vertical lines. It shows like this for about 1min before it goes into standby mode & the blue power...

Depends on what is causing it...

Vertical bands of faint black are generally caused by filtering capacitors and can be found in the power supply or the 5 volt supply or even the Video processing is not an easy task to identify the source of Video hum bars.....we also call them Jailbars.

Another problem seen is faint black lines caused by the TV set being in 4:3 mode all the time....right at the edge of where the picture ends and the black pillars begin, we see a faint black line that never goes away and is normally seen with a full screen....

That is actually image retention, but it's caused by the crystals that create the picture becoming polarized or ionized over a very long period of time....and it's not easy to DE-Polarize them !

But there are some theories out on how to do that....
Certain people suggest running the TV overnight with an ALL-WHITE picture and some suggest an ALL BLACK PICTURE...and some suggest alternating between both !!

Now, a black picture is easy to make, you just deactivate the Video Mute (blue screen) and set it to an unused Video INPUT overnight....

About the only way to make a white screen is to use the USB port for pictures and take a very bright outdoor shot of a piece of white paper that hopefully is out of focus too....That would create an all-white picture that you can plug into your TV set overnight....

Now if you decide to try this, deactivate any displays on your TV set...all you do is press the display button until the Video and/or USB input numbers disappear....

Next day , set it back to normal TV and see if it's gone or if it's REDUCED....try it again if needed, or try the exact opposite if you see NO RESULTS....

Hi-\r\n Thank you for being here- We were watching our Sharp Flat Screened TV, beautiful nice picture. We noticed when we hooked the cable up for Direct TV in our new home, the input connection point was...

With Direct TV, you should use the video input (composite video- yellow/picture, red/right stereo, white/left stereo)
component video- (green/video, blue/video,red/video white/left channel stereo, red/right channel stereo)

the antenna connector should never be used anymore unless connecting an outdoor antenna or VCR.

if one of your input connectors is damaged, it is not likely that is will be repaired without replacing the entire circuit board (expensive!!!).
just use a different "input"- there are usually at least 3 on most TV's

I have a Hitachi 50v710 it has a yellow tint in the middle of the screen can this be fixed thanks

This tv is an LCD projection one. in it the image is generated this way: a bulb makes the light; this light is divided then passed thru 3 small LCD screens; the 3 pure color images are mixed together by a prism then passes thru a set of fine plastic lenses (this is called the optical engine) ; from there the final image is projected on a screen.
The entire image quality is determined by the quality of the optical engine - if something goes wrong with it it's clearly visible on the screen. In your case the heat of the bulb has deformed the first lens, and that has caused optical aberration - color shifting.
This is fixable, the optical engine will have to be replaced - you can't replace just a single lens, it's a sealed unit. Unfortunately it's not a practical solution: a new optical engine will cost you over $800.
Use the tv as is until you can save enough for a new one.

Blue blob on screen of 50V500 tv

it's not the lamp (obviously, as you found out). the light filter on the blue lcd has a burn mark on it and needs replacing. many companies don't sell parts for the optical engine (where the filter is), so you may have to purchase the whole engine, which tends to be pricey.

KDF-60XS955 Blue dots all over screen. Lower left corner of screen has a small blue cone shape. Will a new bulb fix this? If yes how do I replace the bulb?

It is problem of light engine (optical block) in TV and Lamp replacement does not solve it.
TV needs replacement of light engine, that is costly part.

Lg lcd tv picture goes in and out with "boxes" on the screen

This sounds like the power supply that feeds your back-light is going out. This repair should be done by a qualified technician

White Screen of Death. TV locks up

You will need to replace the power supply or get fix because there aren't too many service parts available anymore.
