Mitsubishi WS-65511 Do you know the part number for the seven capacitors I need and what should I loook for after I open up the DM. Should they look swelled or smell or something. I'm ready to get started but wanted to line up some replacement parts. I called a local place but they need the part numbers and specs to see if they have them.

Thats caused by weak capacitors on the DM board which cannot recharge after the power has been restored. Very inexpensive repair . The WS48511 - WS55511 DM repair kit from www.tvrepairworld.com has the capacitors and the CD with repair instructions which should solve the issue of the steady blinking green light.

Thats a very common problem caused by failed capacitors on the DNM power board. Repalcing them should solve the issue. You can get the DM repair kit for your model at www.tvrepairworld.com which contains the upgraded caps and the CD with repair instructions

I used to have a WS55909 and had this problem. The light is supposed to blink for one minute while the DM (digital module) boots up after a power loss. If the light continues to blink indefinitely, there is a problem with that board. The DM power supplies are known to have faulty capacitors on these models and will need to be replaced. If I remember correctly, there are (7) 1000uf 25v capacitors and they should be desoldered from the board and replaced with 35v ones. Note that my TV model already had 35v caps but changing them solved the problem: electrolytic capacitors have a much shorter life than other components.
The DM is on the left side and is where ANT-DTV and the IR repeaters plug in. The power supply is the board above the main DM board inside the DM case.
If this sounds too technical for you, get a new TV because a repair guy will charge you more than the TV is worth. In other words you could get a (30-46") LCD TV for the same price.

Front Keypads go bad alot on these sets,replace the Keypad.

The Bulb in the unit needs to be replaced. To confirm, look in the manual for the set and it will explain the flashing lights by the numer and duration of flashes. Hope this helps.

The steady green blinking led is due to the DM not completeing the boot Cycle. You can get the repair kit at the following link which contains the replacement Capacitors and step by step detailed instructions so you can do the repair yourself. Very inexspensive Kit

I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

yes the capacitors on the DM need replacing. depending on the chassis some have 4 capacitors on the DM board where as other chassis have 7 capacitors on the DM power supply that are causeing the problem. If you dont know which chassis your has go to this link and leave them an email they can help you figure it out,

often the capacitors will show no visible sign of swelling. 90% of the time the blinking light symptom is caused by those capacitors

Yes we have them, they are a little exspensive as they are so hard to come by. But we do have them as we rebuild alot of mitsubishis, not just the DM boards but the newer FMT and PWB boards have those same capacitors and mitsubishi has bought up most of that cap just to do their repairs at their authorized repair facilities.
