I have a mitsubishi model WS-55511. The green light keeps blinking. Have reset by unpluging and then pluging back in and holding the reset but for 5 seconds and press the power button. worked once, but know the green light is back on. And will not reset again. what seems to be the problem

rforester,

This model Mitsubishi has some capacitor problems with the DM board and the power supply. See my tip at http://www.fixya.com/support/r7065906-mitsubishi_turn_flashing_power_timer which explains the problem and where to get the parts to repair your unit.

Thanks for using FixYa and for the great rating.

After you turn on and green power light comes on and then goes out:

Press and hold both the menu and input buttons on the front of the set for at least 5 seconds and release both buttons.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it 4 more times.

Let me know what error code and I will tell you what it means. If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

Do this: When you turn it on and the green power light comes on and goes off:

On the front of the set press and hold BOTH the Menu and Input buttons at the same time for at least 5 seconds and then release both.

This model has a self check: The green power light will then blink a two digit error code: most common is 2 blinks, 2 blinks and a pause and repeat the error code at least 5 times.

Let me know what you find and I will tell you what it means.

I hope you get 2,2 as it is the most easy to resolve.

This set has some capacitors on the dm board that go bad, they need to be replaced.

Check C9B01, C9B02, C9B03, C9B13, C9B14, C9B17 and C9B18 (1000 uFD, 16V,
105C) on the DM Power PCB located within the DM Assembly. If they are bad, replace them with
part # 181P734030 (680 uFD, 16V, 105C).

Listen: you need to wait for the set to first shut off! then push on the TV(not the remote) Input and Menu both at the same time for 5 seconds and then release---the power light will then blink---this model has this feature--

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:


UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

replace the capacitors on the DM board. Heres a link to the repair kit which contains the replacement capacitors and instrucions of how to do the repair.

I had the same problem with the blinking light on the front of the TV and it would not power up. I read all the problems everyone was having and thought I was going to face a huge repair bill. The service guy came out, pulled off the front panel where the speakers are and disconnected the circuit for the front display panel. 3 1/2 minutes in my house, $90 service call. Apparently, when you give the TV too many commands at once, it's safety feature is to"shut down and lock up". He mentioned also that sometimes when these sets get to be about 4-5 years old, the wires in front can "leak" causing a shortage and then locking up the TV. I keep the circuit unplugged and operate the TV solely by the remote. Give it a try, what can it hurt!! Hope this helps.

Press in together the menu button and the Device/input button on the set and hold them both in together for 5 seconds and see if the led will blink a two digit error code, then respond to this same post and let me know if it gave a error code and what the two digits were.
