I have a wd-57731 The lamp light blinked orange. i replaced the lamp turned the tv on and the timer blinks green for one minute and then the lamp light blinks orange again. It won't turn on. Can you suggest anything?
You have a bad ground on a convergence IC. You will have to carefully pull this board out and resolder the pins. If this does not solve the problem you will have to replace the ICs. I have saved a few of these TVs with just a resolder job. Thanks for asking!
What a great tv this is Mitsubishi did a fine job making this one, but......only an authorized mitsubishi servicer should repair it. This set records diagnostic led codes that the technician receives to help determine where the problem might be, not the problem, but in which circuit it might be. The one thing to try is, unplug the tv , let it set for a minute, plug it back in , turn it on and hope it reset the micro. Next , call for mits. service.
I gave this advice to someone with this same problem so here it is again:
It sounds like your shutdown circuit is being activated. This is due to excess current being drawn. This usually happens in the High Voltage section of the TV or one of the deflection stages. Due to the nature of this problem I would suggest that you take it to a local TV repair shop or have a TV repair person come out and take a look at the issue. The HV section is dangerous and should be dealt with by a qualified TV repair technician.
Probably, the selftest fails while turning on. If this is the case, press input&menu buttons at the same time for 5 seconds, then the green led will start to blink. Let me know how many times the led blinks.
