Question about Mitsubishi WD-52525 52" Rear Projection HDTV

2 Answers

TV won't come on. Green light blinking.

I have unpluged it and also pushed the reset button several times. Lamp doesn't seem to be the problem. It has don this before in the past. But simply unplugging it has worked this time??? Green Timer/Power light blinking and cannot get any response from remote or buttons on TV, will not turn on. Reset button does not resolve problem and turning power off to unit has not solved problem either. Return power to unit and same situation.

Check the power supply for bad capacitors usually they are swallen,if not check the DM board for bad capacitors too. they are (4) 1000uf/16volts. 105 degrees.you have to replace them with 1000uf/25volts.105 degrees. now i don't know if you have the ability to disasemble the tv to get to this boards,if you don't just call the repairman. and tell him about this caps,ok.

The fuse on the main board is mostly blown this causes this problem.

    if the fuse is perfect then the problem is of the main power supply board the capacitors on the boards are either loose and needs to be tighten.
    or the capacitors r blown or bulged up and needs to be replaced.
    start from checking fuse on the main board.


    thanks.

    the board gets this types of problems due to moisture collected on it and immediately when u start the tv due to that moisture it gets short and looses.
    also due to heavy electricity passed from the tv at certain period when the tv was on and board could not handle that extra current and gets short.
    thanks

Blinking Green Timer Light


I suspect the lamp area is VERY dirty as is the cabinet's filters and fans. This causes great stress on your tv and lamp. Take the time to clean all of them fully. Is the unit in a dirty area? or in a high temp area? DLP's dont like high temp or contaminated areas as they are NOT air sealed units.

Mitsubishi Model WD-52725 timer green light blinking fast


My Mitsubishi WD52725 will not turn on...the timer light is blinking. We pushed the reset button, unplugged tv. Just got off the phone with Mitsubishi customer "service." After answering numerous personal questions, and being on hold for several minutes, I was told that the only solution was to push the reset button. Duh! We'd done that several times with no change, which is why I called them! BIG WASTE OF TIME!!!!

TV was working earlier, today came home no green power light no nothing


I looked up the manual online - after you replace the bulb, you need to reset the bulb life timer. Using the TV remote push the menu button, SETUP menu, select the lamp reminder option to reset the hours to zero. That might help the status indicators.

Blinking green reset light


Can you please supply us with the make and model as well as the blink count of the green light. That count should be indicating the problem circuit. Once that info is posted, we should be able to give you more details and possible solutions.
