Question about Sony KV-32S42 32" TV

SCREEN GOES BLACK AFTER 1 MINUTE

AFTER I TURN THE TV ON FOR A MINUTE, THE SCREEN SHRINKS TOWARDS THE TOP OF THE SCREEN FOR A FEW SECONDS BEFORE THE PICTURE TURNS UPSIDEDOWN THEN TURNS BLACK. DURING THE ENTIRE TIME YOU CAN HEAR THE CHANNEL YOU ARE WATCHING PERFECTLY. TO FIX THE PROBLEM A FRIEND TOLD ME TO TAKE THE BACK OFF AND BLOW ALL THE DUST OUT WITH A COMPRESSOR, SO I DID. IT WORKED FOR A COUPLE DAYS WITH NO PROBLEMS BEFORE THE PROBLEM REOCCURED. I WOULD APPRECIATE ANY HELP. THANK YOU.

In electronics dust has nothing to do. cleaning will not solve your problem your problem is due to trouble in vertical section. mostly it is due to electrolytic capacitor in vertical section is defective.it is common problem. also check supply to vertical section. "THE SCREEN SHRINKS TOWARDS THE TOP OF THE SCREEN FOR A FEW SECONDS BEFORE THE PICTURE TURNS UPSIDEDOWN THEN TURNS BLACK." is called fold over. regards thanks

My daughter sprayed fabreeze on our 60' sony flatscreen and now I cannot get it to power on. She sprayed a few spritzes on the screen and after a minute or two it shut off and will not turn back on.

Hi, it's better to take your TV to a service center or call a TV service technician because electronic boards inside could be faulty and they need to be repaired or replaced.

Plasma tv screen goes black once you turn it on. Only sound

I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.

Picture Shortens, Converges, eventually the set shuts off - $50 for Correct Solution

Open the TV amd turn it on in a position you can see the picture, possibly through a mirror. Now gently tap all of the metal heat sinks on the circuit board until you find the one that is sensitive it will have a small chip mounted vertically on it, with probably like 7-10 pins. The number on the chip will most likely be an "LA****" number. Now turn the circuit board (UNPLUG FIRST) over and resolder the pins. This is your problem 99% of the time. Be very careful there is High Voltage inside this TV.

Tv screen goes black for a few seconds

do you get sound while screen does black? what do you mean by "until eventually it has turned black and will not come back"? is it black from the minute you turn the tv on untill you turn it off? if sound is good but picture is black, it may be the resault of a fried monitor tube, in this case replacement will cost alot. if sound is dead also, them it is probobly power supply related issue. get out your DMM and measure the voltages in the power supply. When the screen goes black, is there still regulated B+ going to the circuitry? Do you still have HV? Is the filament of the CRT lit? Does the set still have a raster (you may have temporarily increase the screen setting to see it)? Do you measure any of the flyback derived B+ voltages that go to the video processing, tuner, Vertical Deflection, and other circuitry?
