Shadow problem on 56H80

The unit has been toruble free......now it seems that the guns are badly misalligned. It is way off on the right side, the center is perfect and the left gets worse as it travels from the center.

The unit is 5 years old.....too soon to go to the dump, but I don't want to invest too much in it......any guess to the problem or possible cost to repair?

THERE IS A YELLOW SHADOW IN THE LEFT SIDE OF A BODY WITH ANTHER BLUE SHADOW IN THE RIGHT SIDE OF THE SAME BODY PLEASE ADVICE ....


Hi alalfaraj,
If the symptom didn't cure by convergence adjustment through the remote control, this is an indication of faulty convergence board inside. You may replace the convergence IC's and some of the resistor around because its already gone bad. You may also replace the entire convergence board for your convenient. If the board replaced with new one, your unit will back to normal again. Also, consider bad solder joints in that area, it will do the same symptom like what you've encountered right now. Find it first and re-solder. If you don't have necessary tools and test instrument and can't do the job yourself, I would advise you to look for a qualified technician to isolate the problem.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

My TV works fine. The only problem is that when i'm watching a movie, or playing PS3 the field seems dark. Sometimes is FIFA Soccer, in the shadow, i can't even see my players because of the dark...


It is possible that there is a allergy that is growing the blue and green gun, it will not grow in the red gun, and it blocks the video and makes it look dark, on the greenish side. To fix the problem, you have to change the coolant in the guns, and then it will look like new again.

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.

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

Screen Discoloration Problem


dJbsharp1: Check if the cleaner you use discolor or remove the clear of the screen. Touch the cleaned part and somewhere else on the screen to see if is rougher than the part you didn't clean-up. If this did not occur you can clean it up completely and watch the difference. If it's rough as I described you, a replacement will be necessary. It is easy to replace. Very easy.
