SOURCE: Mitsubishi TV WD-62527 will not turn on

Hi there, this is most commonly known as power board failure in the industry. the capacitors are blown. if you are experienced in inspecting circuit boards this will be helpful. you will have to disassemble and pull the power board and preform a break point test. the bown capacitors are easily picked out. they will be swollen and discolored. If you are not comfortable with disassembling this set, i suggest a service call. just tell the tech you are experiencing a power board failure.

SOURCE: Rapid flashing light and now power-up after power outage

Replacing those capacitors usually solves the problem however sometimes the issue is back in the power supply. Make sure the 12 volts be supplied to the DM module is present. If not you'll need to fix the power supply.

1.) Most of these sets have a receiver built into the back(large metal box on left side as you look from the back.)

2.) Two possible reasons for green light constantly blinking(it is the receiver booting up if the set is disconnected from power---light should blink for about 70 seconds and go out).


3.) First reason: The recessed micro switch on the keyboard marked reset may be bad--does not happen a lot but it does happen. Easy way to see if this is the problem is to remove front speaker grill---and inspection plate behind it---from the keyboard you should see one or two groups of wires(they come from the keyboard) follow them to the right and unplug both(they are different and marked with letters). This takes the keyboard out of the circuit---you should still be able to turn the set on with your remote(remote receiver is behind the screen.) IF SET NOW WORKS YOU HAVE TWO CHOICES--USE IT ONLY WITH THE REMOTE OR HAVE SOMEONE REMOVE THE FRONT KEYBOARD AND UNSOLDER THE RESET SWITCH--the switch can be replaced without replacing the keyboard(it is a small circuit board with all the micro switches on it.)

4.) If disconnecting the keyboard does not fix the trouble---you have a problem in the "Receiver"----it happens on these sets and usually is repairable--Mitsubishi no longer sells this part and it was very expensive when they did---if disconnecting the keyboard does not cure the problem---let me know and I can give you options for getting the receiver repaired.

5.) Let me know if you have questions and if you need more advice reply to this post here.

SOURCE: green light blinks constantly. reset doesn't fix it.

This set has a lot of problems but I have news for you that I recently discovered from a authorized Mitsubishi repair center---


Mitsubishi has had so many problems with this set that now they sell a complete Chassis replacement for this set for about 200 dollars--You will have to go to a authorized center---no more trying to fix individual boards in this set...if you are in doubt--Google the model number and you will see all the problems this set has had---

Contact Mitsubishi and I think the best thing you can do is get the Chassis replaced--


If you have more questions about what I am telling you let me know---I think Mitsubishi is trying to avoid the class action lawsuits that are in progress against them for this model.

My JVC flat screen won't turn on, tried unplugging and resetting. Stand-by light is still on. And it's attached to a surge protector than to the wall. I've only had this for 1 year.


More than likely its bad capacitors on the Power supply very common problem with most models. You can get repair kits or replacement power boards from www.tvrepairworld.com

Re: tv kdl-55ex620 red light blink 8 times Do a Power Reset. 1. While the TV is off, unplug the power cord of the TV from the electrical outlet. 2. Let the TV remain without power for 60 seconds. 3. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.) 4. Turn on the TV. 5. When the TV powers on and a picture is displayed, reset the TV to factory default settings.
  • If the Reset message does not appear and the TV turns off and on, begin again from step 5.
  • If the standby light begins blinking eight times, return to step 1.
6. After the Reset message appears, allow the TV to reset. Do not press any buttons on the remote control or on the TV and do not make any other adjustments for 1 minute. 7. Unplug the power cord from the electrical outlet. 8. Allow the TV to remain without power for 10 seconds. 9. Plug the power cord back into the electrical outlet. 10. Turn on the TV.
  • The initial setup screen displays if the above procedures were performed correctly.
11. Follow the on-screen instructions to complete the initial set up. 12. Perform a system software (firmware) update.

This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.


Let me know if you have questions and try disconnection of the front keyboard FIRST.

Hi,
If the led light flashes green continuously, the fault came from the DM power supply. The faulty parts there are the electrolytic capacitors. Let me know if your handy with electronics and I will assist you to fix it yourself.
