    i have shadowing effects on my sony grand wega. a year ago it started as a couple dots, now its multiple areas that are fist sized. They are light and trasparent but none the less VERY IRRATATING. It has baffled multiple repairmen, it is not from the projection. It shows when the tv is off as well.

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.

Model 50UX58K - picture has distortion & shadow on right side of screen


Hi, if the shadow is colored lines then you probably need the convergence ICs and possible reisitors near them replaced .
If the shadows is just like a ghost of the image or a bar from top to bottom, then check if it does it on every input (dvd for example) , there are blanking bars that you can't see past the edges of the picture and when you have a bad cable signal you can see the ghost of the blanking bar sometimes. if it does it does not show the shadow when watching a DVD then its a signal issue with your cable/satelitte .
If your convergence is the issue, try the adjustments first and if that doesn't correct it, you can replace the ICs using kit # x480293 or stk392-110 (2 ICs) soldered in very technical for even a technician.
repairman cost about $250-$350
hope this helps

Blue image shadow on one side of the screen..Help!


Perfect! That is typically called "Ghosting" where there is a faint image shadow behind the image on your screen. I'm glad you were able to get it fixed!
