Question about Sony FD Trinitron WEGA KV-27FV310 27" TV
Everything seems to be working fine except there is only lower half the picture and a bright line in the middle. This tv is about 4-5 yrs old and i worry that the repair cost will be equivalent to the replacement cost. I am wondering if i can fix it myself if i know what part to replace. Thanks tom
SINCE YOU HAVE HALF THE PICTURE THE VERTICAL IC IS STILL WORKING. THE PUMP UP CAPACITOR AND THE OTHER ELECTOLITIC CAPACITOR IN VERTICAL CIRCUIT MAY BE BAD. THE CAPACITOR IS USUALLY 100UF OR 220 UF AT 35V REPAIR EST. IS $135.00

I have the exact same TV and the very same problem! (sounds like a SONY bug to me!) Curious of the original poster (Layton) had tried the suggestions and which one fixed the problem? Thanks! ALSO, as a caution, I googled replacing the electrolytic capacitors and it can be very dangerous if you touch certain wires, can cause cardiac arrest according to the site http://www.nmr.mgh.harvard.edu/~reese/electrolytics/index.html ... SO PLEASE BE CAREFUL!

I DON'T THINK THAT VERTICAL OUT-PUT IC IS FAULTY BUT DECOUPLING ELECTROLYTIC CAPACITORS ARE. JUST REPLACE ALL ELECTROLATIC CAPACITORS IN VERTICAL SECTION AND I HOPE PROBLEM IS SOLVED.99% OF TIME THIS PROBLEM COMES BECAUSE OF THAT.IF VERTICAL IC IS FAULTY THEN YOU WILL GET A SINGLE HORZONTAL LINE AND SUPPLY RESISTOR OF THAT IC WILL BLOW OPEN AND TV WILL GO IN PROTECTION MODE.
