Hello,

mostly likely, the fault should be from the DM board. But its really very hard to guess a TV part without actually testing the board to know the exactly fault. You can consult the service manual for this TV. It will direct you to the fault of the TV and a way of fixing the fault.

You can find the service manual for your TV on the below link. make sure you read every information on the manual thoroughly, to get to the root of the problem. Also, you might print it out if possible. This will really help a lot in solving the problem.

Allow the link load completely because it will actually take some time to load on the pages fully, because they are many.

I wish you good luck.

Hello,

The reason your laptops light keeps blinking and there is no display on the screen is because there is a problem on the board of the television.

There is power getting to the television, but the board is not receiving it to start working, that is why it is blinking.

First try to secure its connection to a power source is tight and not loose, then turn it on to see what happens.

If it does the same. all you have to do is to change the main board of the television. After doing this your television will be in good condition again.

Take care

Ws-55511 green light changed caps. where is pico fuse located ?


There are at least two pico fuses in the DM unit along with the caps; DM is large metal box on left as you look from behind.

Blinking green light that does not stop means problem is in DM unit that is not booting up.

If you have questions let me know.

The power wet off and now the timer green light is flashing and it wont turn on model # ws 55511


Thats caused by the 7 capacitors on the DM power board. They discharge when the power is lost and then cannot recharge when power is restored and the indicator light will blink non stop indicating the DM has not completed the boot sequence. Replace the DM caps. The WS48511 - WS65511 DM repair kit is the correct repair kit for your model. You can get the repair kit from www.tvrepairworld.com

Ws-55511 replaced all 7 caps in the dm, still wont power on


I have seen this only 2 times----you may be able to unsolder and remove the reset micro switch---you have to remove the whole screen to get at it---the micro switch board may not be available---the switches can be tested with a ohmmeter set to high end and of course should not have a reading across them--I bet the reset switch is bad--you can remove it and put the keyboard back---most of the Mitsubishi sets use the same type of switches--Only other thing is leave the keyboard disconnected and just use the remote.

Glad you found the problem.

Ws-55511 DM 5volts draged down blinking led


Hello,

Did you check the caps on the DM board? They usually go bad after a period of time. Remove the DM board and the metallic cover and there should be 4 to 7 capacitors (There are different revisions of the DM board). Check these caps also, replace if needed.

Thank you,

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.
