Question about Toshiba 40RV525U 40 in. LCD TV

1 Answer

Tv turns on but the screen turns gray and the speakers make high pitch sounds

When I turn the tv on, the picture will come on for a couple seconds then it fades to a gray-ish color and I can kind of see the original picture. When this happens, The speakers make a loud chirp/ high pitch sound. Nothing else happens after that. Every once in a grate while, the tv works fine.

It sounds like the video output isn't
working its most likely a component
failure 1 thing you could try is connecting
a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

Picture goes black with gray fuzzy lines ~ 1/2" apart horizontal.


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

Picture is Gray, does not show any color


Are you using component cables (red/green/blue)? Check your connections to see that they are all seated properly. When using component cables, if only the green is plugged in, it will give you a black and white picture. You will get color once you plug in the red and blue.

What kind of sources are you using? what kind of cables are you using? Need these kinds of specifics to ehlp you out.

Faded Picture


I would have to say it does sound like the CRT is reaching its end. The thing that points this out that the picture gradually gets a little bit better as it warms up. It most likely isn't worth the cost to fix it.

FADING TO BLUE SCREEN


Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer
