SOURCE: SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK

You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!

SOURCE: Sony TV - Loss of half the picture

sarge, it sounds like the vertical output IC went bad on you. If it was a bad connection or a bad capacitor, your picture would have been a straght line across the screen. They call the output section of the IC a push-pull type of amp, so the top half of the sweep IC went out. If you have had some soldering experience, and or experience with solid state repair, locating the bad IC and replacing it is no big deal. If you havent, stay safe and call in a pro to assist you in this repair, as there is alot of high voltage inside this puppy that is still present even if the set is unplugged. It should not cost an arm or a leg to repair this set. An honest repair on a set like this if you take it in should not exced 125 to 150 bucks. Good Luck PS Please dont forget to rate this thread.

SOURCE: Sony FD TRinitron WEGA,

Just went thru the same problem with my sony kv-34. There are two IC's on the D circut board located on the left side looking from the rear. If you can solder 18 pin IC's without making a mess it is possible.If you have a friend thats real good with a pencil tip solder device. I recomend putting sockets in where the IC's were as you won't have to worry about overheating stuff next to the IC's.Do a google search: Sony led flashes ad select the second hit in the list.

Good luck
Rich

Sony WEGA 36" Trinitron HD


Check for unit posting any blink codes on the timer LED. Google "sony blinking codes" for the explanation. Try turning unit off for 4 hours to force a hard reset of your set, you need to unplug it. Sounds like a low voltage problem in the HV circuit.
