The problem with this model is the large parts due to poor wave
soldering. Locate the transistor Q605. Using a
small wattage soldering iron melt the solder and add a little solder to
all the large parts in the area. Small wattage = 15 to 30 watt. Stay
away from the surface mounts they are not the problem. I resoldered the
following: D647
Q605 C690 D645 D620 R691 Q691
These parts are
located on the main board, the one the power cord connects to.
Carefully press the clip on the left side of the board (as you look at
it from the rear of the tv) carefully pull the main board back and out
of the rails. You will find the parts on the right side of the main
board about 2 inches over 2 inches down.

pls rate my suggestion....
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
