Mitsubishi WS-55909 55" Rear Projection Television Logo

Picture was fine, then lines diagonally, now light

Picture was fine, then lines skewed diagonally, then became light green background with red and blue lines bowed about 1 inch apart. The set turns on but will shut down about 30 seconds later and have tried rest several time.

The Blue lamp is no longer projecting. Is this as simple as a lamp replacement? Can I check the resitance through the lamp to be sure that is an issue? The set is 7 years old with but has less then 4000 hours on it so I really do not want to replace it yet.

    Figured out the issue. the Netcommand set up was for composite HD input and I was using component. The tuner compensated for a while.



    Didn't touch the TV over the holiday's and recently reconnected with the standard 480P inputs. TV worked fine so I moved the connections back to the 1080i inputs and and also reset the netcommand assignment. That is when I figured out I was using the wrong setup.

    Problem was the Netcommand defaults to composite HD inputs. I was using component inputs. The tuner compensated for while.

    Deleted all the TV assignment and setup Netcommand again. No issues now.

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hitachi 65F59 65-Inch CRT Projection HDTV picture skewed.

The convergence output IC's have failed and need to be replaced. Sometimes when they go biasing resistors burn open also. These are large amplifiers mounted to heat sinks and have as many as 18 pins soldered into the circuit board. Better be handy at desoldering even if it's only the IC's that are bad.

Picture Problem

In that set its usually a bad picture tube. The lines you are seeing are called retrace lines. You can take it to a shop and they may be able to rejuvenate the tube

Too much green color

Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.
