Check and re-solder the connections on the 2 convergence ICs in the middle power board. they are going to be attaches to the biggest heat-sink in the tv. if the re-soldering doesn't fix then replace with STK392-570 i would replace both but if you look at the board you should be able to figure out which chip is responsible for the vertical and which is the horizontal convergence. each IC converges all 3 colors but one is responsible for one axis.

I have a Mitsubishi HD 1080 55


Your unit has some sort of Thermal problem either with the PSU fault, or a thermal problem elsewhere that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. T

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Mitsubishi WS-65907 rear projection TV HD goes blue.


I would look at the source for the Hd signal as being the problem--if you are using some kind of cable or sat box it will deliver the signal to the DTV input on the back of the set--this is the HD input for this set.

It is possible to have a problem like you describe be one in the set--but very unlikely----have you looked on that green signal board for any signs of Glycol?

Anything that will produce a 1080 signal to the DTV input should tell you if the problem is the set or the source of the HD signal that is causing the problem.

most likely the convergence Ics have failed. Check F9a04 and F9A05 pico fuses if they are blown you will need to replace them and the convergence Ics.They are located on the center board they are green and look like resistors without the color band. see the photoa193b32.jpg82b89b8.jpg
