    Picture has blue and green shadows> Happened all of a sudden, was working fine before this. Is this something that can be fixed at home or does it need to be taken to a shop. If the shop is required, how much am I looking at?

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.

Sony Trinitron picture turning green hues


Nowadays CRT's do not have good quality shadow masks anymore. After heating up a little they can give a so called "blooming" effect giving a blue an yellow leaf effect large over the screen. Reason nonparallelity in deformation of the shadow mask.

PINK/GREEN SHADOWS, LINES


Here is what I was able to find out about your problem from sony: This issue is usually caused by some type of nearby magnetic interference, such as unshielded stereo speakers placed too close to the TV. These spots can be small or large and will normally be red, green or blue, but sometimes appear purple or pink. They normally occur on the sides or corners of the screen, but can also appear in the middle. To resolve this issue, move any stereo speakers or other electronic devices away from the TV; a minimum of 2-3 feet is recommended. If the situation is not remedied immediately, unplug the power cord of the TV from the electrical outlet for 20-30 minutes; repeat this process one more time if the issue is not resolved the first time. If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer in your area. Hope this is helpful:)

It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

My computer did this and I think my TVs just gone the same way. Was definitely a loose connection somewhere. In the computer monitor it was because the pins in the plug were slightly bent and if I moved the wire the picture got better. In the end I had to replace the connecting cable
