I have done everything in your 10 stickys before attempting to solve my problem. The firts attempt I bought bad parts and blew a fuse when I replaced the IC's on my mits 55857...I then used one of your vendors...Acme...in Orlando...awesome service and I strongly recommend them. I replaced the IC's again and the pico fuse that had blown and my TV worked magnificently...I used the auto (factory default) convergence and the picture was beautiful! I was amazed myself and my family was dumbfounded. However, after we went for a walk on the beach after our Thanksgiving gorgefest I went to turn the TV on and now I have the dreaded 2-3 second on and off power on problem. I assume I have another blown fuse or something. However ... it worked flawlessly for 5 hours yesterday...and today...nadda! Do you have any suggestions other than the 10 pages of stickys? I read all 292 posts and am amazed at the content you have amassed. I have never checked my resistors or my power supplies (+ or - 24 volts). I'm assuming that if I find the back fuse that I can replace it and it'll work for awhile and my problem will again return. Thanks in advance for such a professional webinfo site! Cheers and Happy Turkey Day! Utah
