    thank u very much for your help

    the squiggly line is there on every channel and every source unfortunately

    it kinda looks like a peice of string dangling back and forth in the wind if that makes sense

    How about cleaning inside the rear projection cavity??

    If a spider web gets between the lens and the back of the

    screen-------two ways to clean a Mits---

    1) Remove bottom,rear cover---reach up inside with duster on

    extension pole and knock down spider webs.When finished,

    wipe clean RGB lens caps with soft cloth.


    2) Remove speaker grill cover in front,then remove hidden screws

        holding screen assembly,lift up/out.

        Clean out cobwebs and clean lens caps,reassemble.

Thin white horizontal lines!!! I've had my WEGA KE-42M1 for 5 years with no problems until about three months ago. After about an hour being on, there are thin white horizontal lines that move randomly...

Sounds like your TV is giving out, plain and simple.

If this doesn't sound right, then only one thing comes to mind. Have you moved the TV recently? Are you using a different coax cable, (if using cable that is). If so, just change the cable back to the previous one and you should be fine.

Hi kmb0516.
Depends how old the set is, if it is more than 5 years old, time to tell it goodbye, if it is less, might be worth fixing.

I believe the problem is in the vertical output section, it sounds like the picture has shrunk.

Hope this helps, Greg.

Light green and pink spots on my hd tv!!!

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

Hello hope. Try pushing in the input and menu buttons on the set and hold them both in together for 8 seconds to see if the Led will blink a two digit code then let me know what that code says. I can get you a link where to get a new power supply, but that may not be your problem. Try this test an see what the led blinks if anything then let me know I will try to help you determine whats wrong. I am a specialist with mitsubishi projection units.
