    I also have a mistubishi ws-65909. There is a flashing green light on the
    front timer that blink constantly for a minute or so then stop for few seconds then blink again and repeats the cycle. The T.V. will not turn on at all. Press Device+Menu or just Menu for about 10secs and nothing happens. Power board has just been repaired by Mitsubishi a month ago.

    The front green light flashes all the time and power will not come on. This is the third time that it happen on this TV. I think its a falulty componet on one of the three main mother boards.

    I checked the main fuses on the convergence board and input power. Found no problem there. Don't know where to check for the thermal switch?

    these are garbage, I bought mine in Jan 2004 for almost 4k and it has been repaired once. Now the part is not available and all Mitsi will do is offer me a store credit of $1195. the sad part is that this was not even our primary unit and really didn't get much use. Now I'm stuck with a little credit and a big box of electronic **** in my basement. Buy a SONY!!

I bought the mitsubishi black diamond gray 65819 is under warranty and had same problem , turns off like after 2seconds ,it can be fixed people but u need a sears tech, I had one come out and was told they no longer can get the part ,but he had to take it to repair it and yes its was a steal for me ,depending where u live the cost for me would have been $350 for part,$200 labor its the board that the power cord is connected to in tv... I live in s.a. texas , the unit that set up the service is 9905 ,the repair unit is just down the street from them off culebra so if u get tech says cant repair it this one does,it helps if u have the warranty or protection agreement

You need to hold down enter and device until it stops blinking

Sounds like a convergence problem which is common in these sets

This model uses two of the stk394-250 convergence output devices or chips.

I replaced the 4 capacitors on the DM board and got about 6 months out of my Mistubishi WS-55613 projection television. Now it is doing the same thing again with the blinking green light and no power. I...

For their cost it's probably worth trying to replace the capacitors again.

If there's space around the capacitors then I suggest you get high voltage rating i.e if the existing ones are 16V then get 25V.

Also worth checking for any other damaged components or scorch marks on the PCB.

The flashing green timer light after a lightning storm seems to be a very common problem with old Mistubishi rear projection TV's. A friend and I had the exact same problem. And the following solution has appeared on numerous posts here and other websites. Thanks to Slinteriors who originally put the retail parts link:

Using this and other sites, I spent $36 bucks and a little time with a soldering iron to replace the capacitors on the DM board and got mine up and running (WS55859). I've never really worked on electronic circuit boards before, but the helpful advice at these sites got me up and running. Definitely check it out before you hire someone or replace your TV:
