Question about Televison & Video
I do not know repair rates in your area but I do this repair in the home for around $350 + service call rate. You can save money if you pull the board and take to a repair shop to have them replace the IC's. These are large STK392-110 (stamped on them) IC's mounted to large heat sinks. I use upgraded IC's STK392-560 as there are too may knock off 110's out there that don't last or in some cases - don't work at all.
Unplug the TV, remove the speaker grill and cover behind it. There will be a small 5" x 8" board near the front of the TV with large heat sinks. This is the board that needs to be removed. There will be several plugs that need to be unplugged from the board and one that runs back through the wireing harness that plugs in deeper in the set (remember where it came from for reinstallation).
BE VERY CAREFUL NOT TO MOVE ANYTHING ON THE PICTURE TUBES OR CAUSE DAMAGE TO THEM.
