Question about Mitsubishi WT-46809 46" Rear Projection Television
I have talked and researched what could be the problem and most replies are that the convergence ic's need to be replaced. I just wanted to know could it also be a power supply problem? I had a service man come and look at it and I feel he was taking advantage of me. I was quoted 1800.00 for the convergence ic's a new power board and 3 lenses. I did the self diagnostic test and the series of flashes are 2.2. When I turn the tv on the green light lights up and then I hear a click and then it shuts off. I have noticed that the color seems to separate green and red but after a few seconds it blend together and seems to be fine until it just shut off after it was on for about 3 mins or so.
You need to adjust the votages going to the crt's. As the flyback transformer starts to go out the voltages to the crts can go up and down causing the tv to shut off. It also causes red, green, or blue arced lines to show up on the screen. It can also cause some color fading in and out or flickering. Adjusting the voltages can fix the problem temporarily but in the long run it's a good idea to replace the flyback. Make sure you read up on how to do this safely.
