No red on mitsubishi ws-65908


DTV is HD input but look to see if red lens is lit====set does have a hard reset which might cure it if it is a issue---it is based at the exact model number, a four digit code and the working Mitsubishi remote control.

Your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless.

The fact that removing the front helps does not really means anything but is good that you have notice,the age of the set has a lot to do with the problem,I am sure it has many loose conections that need to be resoldered regarless,all sets have many components that disipate a lot of heat and over the years the solder cracks and it forms a ring ,this makes the set intermiatnt until no conection exist any more and it stops working for good.What does the unit do when it shutsdown? does it show a picture with lines that is red ,green or blue and then it shutsdown? or it just goes off? if it shows you a color like I mention it could be the picture tube of that color and the repair will be expensive but it could also be a loose conection somewhere in the power supply or the deflection panel,If you are familiar with repairs ot TV's you can possible take care of it but if you are not familiar with electronics call a qualified technician.I hope you can use this information.

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.

Projection red is above other colors


Look in your menu for something called "horizontal static convergence" or just "convergence". Adjusting this will align all three tubes electronically. If physical adjustment is needed, then you have to do this manually inside the Tv. keever

Mitsubishi ws 65807 RED CRT


What I usually find on sets like that is that there is a loose solder joint on the CRT board itslef. You must get to the bottom of the picture tubes, pull off the CRT board from the red CRT and examine all solder joints on that board. Chances are one or more will be cracked, and resoldering all joints on the board should clear up your problem.
