Re: mitsubishi ws-65909

I suspects you have bad convergance IC's

It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.
Don not run the tv till you have it fix you will cause more damage!

I have a Mitsubishi 55"

This set has a convergence problem. You should only need to replace the IC. Part is STK393-110. It sits on the middle board behind the large heatsink. Use a heat transfer compound to ensure repair lasts. If you have no experience soldering (or unsoldering) please use a professional for the work. The traces are fragile and I have fixed many mistakes local DIYers have committed. Goodluck.

Ws-65909 picture and sound are fuzzy, will a new power supply fix it???

It does not sound like a power supply problem. Most of the boards for this set are no longer available from Mitsubishi.

The most common problem these sets have is called convergence. Go into the customer menu with the Mitsubishi remote and select convergence--enter the "advanced" and look at the grid of lines (set will have on screen instructions for this) Let me know more exactly what your picture looks like.

My screen has a blue line that sags from the left side to the right. It is in the top 3rd of the screen. It is not a single thin line.

Your TV has bad convergence IC's. This problem needs a professional Tech to replace these parts. The average cost should be around $450. Call a factory authorized dealer.

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
