My problem started with what appeared to be no sound and no video. After openeing the bottom front of the cabinet I "messed" with the POTS that control the guns (sorry I don't know what the POTS are called.) When I increased each of the top set of adjustments I could see a single line across the screen comprised of each of the RGB lamps.
On the board beneath the blue lamp appears what could be leakage from the blue lamp. For good or bad I attempted to "clean" this with some acetone. While it certainly looks better it did nothiong for my problem.
Initially when using MENU/INPUT I received 1-2 (okay?) flashes for the code. The TV would power on and sit until it would auto-power off due to no input. Sometime after attempting the acetone cleaning I began to get a 2-4 (vertical deflection error) code from the LED. Now the TV turns on and powers off after about 2 or 3 seconds.
What is my next step?
Thanks.
The set no longer powers off in 2 seconds after I turn it on. I do still have the 2-4 code. I've opened the front and the back of the cabinet and I'm ready to try whatever anyone might suggest.
I don't see any other signs of coolant leakage from the blue CRT so what I see on the board may be nothing to worry about.
C'mon, nobody wants to take a stab at this? I have the boards out of the chassis and I'm waiting for some input from the experts.
Does this sound like a problem that would be solved with a tvrepairkits order? I don't see any bulging capacitors or other indications of meltdowns. I find it interesting that I get no sound and other than the power button it is difficult to tell if anything else is working.
Thanks again.
Well, at this point I'm going to punt and put it at the end of the driveway. Somebody is bound to pick it up.
