You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

After having our tv in storage for aver a year, now it has a green shadow to it. What could be wrong/


Not sure I understand what you mean by green shadow. I would check the fluid in the green and blue CRTS and verify they are clear. I would do this if the green color seemed fuzzy or blotchy looking on the screen.

When looking on a blank screen, do you see any arc lines of either green, blue or red? If so, you would need to lower the screen voltage for that particular CRT.

Mitsubishi TV Model #WS65903 - Green Shadow Lines on Screen


Something is not right here--The green is adjustable in the TECH menu--did this person adjust or try to adjust in the customer or the TECH menu?

If you confirm actual model number I can tell you how to get into the TECH menu--yes--green will not adjust in customer menu--it determines geometry and is only adjusted in the TECH menu.

Also, this set requires any convergence adjustments to be done in 480 and then in 1080--if only adjusted in one mode the other will still be bad.

Let me know if you know how to adjust in TECH menu or not--with exact model number I can tell you how to get there.

If this helps you rate this solution as I do this here for free.

Green Shadow


Hello casey43_13 and nanac,
If the rest of the picture is great and only the edge are off, this might eliminate the convergence chip as been bad. This set is noted for bad convergence chip. The next step is that you need to do the convergence adjustment in service mode. This is a very complicated process. If you this you are up to the job of doing it yourself, please contact me by email. I will email you the procedures. By doing this yourself, you must understand that you could make the problem even worst.

Best regards
