Question about Sony KV-32S42 32" TV
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
