Re: Convergence issue on Mitsubishi

Check your error codes first and see what error it's given. If done right it would last. see for how to do error codes

Green hues around objects

Most likely a convergence problem----green is fixed and if blue or red is out of position you will see green outlines.

In the customer menu there is convergence and then advanced which will pull up a grid of lines---take a look at them--all is done with the Mitsubishi remote.

If it is out the two SKT-392-570 chips this set uses will have to be replaced (both).

I have complete instructions for this repair and a source for parts needed---cost for the parts is under 25 dollars.

If convergence is not the issue let me know.

typical convergence problems--no two sets will look exactly the same

Mitsubishi WS-65908 Error Code 24

If you have an ohm meter, check the resistance from F9A04 to ground, and then reverse the leads and check F9A05 to ground. These supply +24 and -24 to the convergence integrated circuits. The conv ic's may be bad. Also, code 24 usually indicates vertical deflection failure as well. One other check to make.....The pic tubes on this set may leak a few drops of coolant onto the boards. Look VERY carefully for liquid drops on the boards or a green and or white corrosion spot or two on the boards under the pic tubes-near the front of the chassis.

Blury screen with rainbow image cannot read words on screen

The convergence integrated circuits have failed and most likely the 2 5A fuses have opened as well. I would find a local Mitsubishi service shop.

Mitsubishi prjection screen WS-65908

You have a convergence problem,all this sets show this problem sooner or later,you have 2 or 3 amps for the red,green blue colors and this amps go bad and need to be replaced then you have to do a convergence aligment from the service mode and not form the customer controls,a qualified tech should be able to correct the problem since is a common one.

Mitsubishi WS-55807 "Bow-Tie" Problem

If your not a tech, its highly advisable to not even open the set because of the high voltage and x-ray radiation issues. Now if your a technician ,you gonna need to get a service manual, Look up the convergence circuit, Find the two or three convergence driver ics, find the b+ feed resistors to those ic, and order the exact replacement parts. if you dont replace all at once, and with exact replacements, you will be in the same boat a few months down the road. This is not a repair a handi-person should consider doing as even if you get the ics replaced, your gonna need to do some minor or could be major convergence alighnment and your gonna need a cross hatch generator to do this. This repair should cost ya about 300 to 400 bucks? Sorry man Good Luck
