Hi gsanf,

Subsequent shutdown of your unit indicated of out-of-regulation in the power supply section. The very common caused of this fault is the dried-up/leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Also, beause your unit was almost 6 yrs old, you must look for bad solder joints/cold solder in that section, it can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding it. Secondary reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

which has the information you need to replace your mirror.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

there are many capacitors that leak on this set and chances are that some of them were missed. Sorry you spent so much money on that repair but Mitsubishi service could have fixed it right for $300.00 because they know where all of the caps are and they burn it it for several days before it leave the service center.

WD-62525: My Green Blinking Fix!!!

Try the ballast that gives power to the lamp,I have the same problem,got a lamp for $109.00 at discount-merchant,thisa is my second problem with this tv in about 3 years,sucks.

mine required a bulb replacement it wasn't that old at the time
don't like being turned on and off a lot

sorry. I did not see your responses. May be due to network issue. Truly sorry again..

If you have a green blinking light,
Most likely issue is with bad capacitors on the DM an FMT boards.

1) Look for bad 1000uf 16v caps on the dm board and the fmt board.

2) checked surface mount fuses (small white boxes) on DM and FMT board

Look carefully for other bad capacitors in the general area.

Start here and let me know the results.

Note, there is a lot of disassembly to get to these boards. Not a fun project.

Hi mburch5717,
This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Leaky capacitor needs a little warm-up to back from functioning but the symptom will get worst if not isolated. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Secondary reason of fault is the microcontroller circuitry. Once you isolated the faulty capacitor your unit will be back to normal again. If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Hope I helped you.

There is a video reset switch infront of the set, try to reset it.

Just in case, here's the 108-page user's manual for your TV:
http://www.hdtvsolutions.com/pdf/MIT_WD-52525_WD-62525_WD-52725_WD-62725_Manual.pdf

Yor "NetCommand" TV remote is a wondrous thing, capable of throwing off anyone.

When the 'Device Selection Menu" is dispayed, and only when the device icon is highlighted,
does the key work, and it also only works when the remote is in "A/V Receiver" mode -
not in "CABLE or DBS" mode, nor "VCR" mode, nor "DVD" mode.
So, (1) set the NetCommand remote to "A/V Receiver" mode
(2) bring up the Device Selection Menu, using the key on the remote
(3) highlight the Satellite receiver input icon (highlighted with a Yellow outline)
(4) press GUIDE on the remote, to swap the analog digital setting.

Also displays ChannelView for Antenna 1 and Antenna 2 - you may have accidentally
set the TV to get its input from the wrong Antenna.

If your TV has lost memory of its DBS source, you may have to re-teach the TV (using the remote)
that the DBS (Digital Broadcast Satellite) input exists, and to which input its connected.
Refer to "Edit NetCommand, Add an A/V Receiver", pages 39-45 of your Owner's Manual.

The red light indicates the lamp has has failed to light. You might just need a new lamp. If replacing the lamp does not solve your problem then the capacitors on PWB-Power need to be replaced or the lamp ballast itself has gone bad.

Its time to buy a new lamp.

The red light indicates that the lamp has failed to light. You need a new lamp or the capacitors on PWB-Power need to be replaced. Try getting a new lamp first.

Hi,
Is it Mitsubishi WD-62525 tv?
Do you get any flashing/ solid light on tv front when it shut down? let me know what it is that light.
When did you replaced lamp last time in tv?
These info will help me to diagnose problem in tv to suggest a solution.
Thanks

Hi, 5 minutes is enough for reset tv.

I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

Cleaning the mirror would certainly elp but be carefull, it is very thin and brittle.

Possibly color wheel or thermal sensor also.
