Question about Mitsubishi WS-55807 TV
I have a Mitsubishi HD WS55807, Had the screen turn blue and red convergence would go off and then straighten back up,but was able to see the program, until the next day when it would not power up at all. Called a local repair service & they took it for a week, they replaced horizonal & vertical convergence hold & power pack and fuses. He said glycol had leaked onto the big chip (Panasonic MN102H57KMA 020U4M85)on the one board. He repaired the leak and cleaned around the chip, then put some kind of sealant on the chip. Said in high humidity the glycol creates a white residue and we could have more problems.
About two weeks after getting it back the screen turned pink. Called the repair man and he came in & cleaned the chip,(Panasonic MN102H57KMA 020U4M85)with amonia. Told us it may need to to go back to factory to be repaired(they don't make replacement boards for this model).
The third time he came back, a week after the second time because the screen went pink again, he cleaned this chip again. I cleaned this chip two times now with amonia, because he showed me how to clean it and said to use amonia.
When the screen goes pink, it doesn't stay pink, it goes back and forth from pink to a clear picture.Is this the problem?
Good day, rickbowers;
This may be your problem, this model is known for this concern. But let me ask you; is there more fluid on the board? If so put some type of "sheild" over mentioned area. Some shops use a thick cardboard or others use a heavy plastic, install over entire area.
Try this first.
Let me know, good luck, big IRISH.
