Yay!! I just fixed my behemoth KV-32TW77. The picture has been flashing intermittently for about 6 months. MADDENING! So Ted, after a working up the courage to just start turning screws (last ditch effort) and risk breaking the thing even worse or perhaps death, the screen screw is a black plastic Philips-head screw located in a little hole, recessed in from the circuit board on the back of the picture tube (not down by the "focus" adjustment). It says "screen" in a little box right above it. I turned it back and forth until I found the right spot. Incredibly easy. Now we'll see how long that it lasts... Good luck with yours!!
