Question about Mitsubishi WS-65809 65" Rear Projection Television

1 Answer

Green and red outlines -- Help!

There are outlines around images and letters (display letters and such). If the set is turned off for a few hours, you can get a good two hours of television watching without it, but then it starts again. It's more on one side of the display than the other. I would automatically assume it was an over heating issue of some sort, however I don't know much if anything about electronics. Just seems like such an expensive item to ditch at the first sign of issues. Help?

    My husband is going to look at it this evening, he knew what IC and Heat Sink meant, so that is promising. I'll keep you posted.

This is most likely due to a problem in sthe convergence circuit. Since it seems to get worse as the set is on, I would look first for poor connections around the convergence ICs. Bad connections can change the circuit characteristics enough to cause this symptom. Resolder the pins on these ICs. These are large blac ICs attached to a heat sink and should be marked STKxxx.
Keep us posted.

Blurring of lettering on bottom of screen


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. 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 and others.
You can get a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*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

You can see some more examples and find a fix herebb0cf99.png

I have a 61'' Panasonic tv that is showing green and red outlines around the figures on the screen. It originally started as just green outlines. Any ideas on what the problem is would be great. Thanks


The convergence is off. The convergence is basically the assimilation of the image on the screen from the three "guns" behind the screen. There should be a menu option to align the convergence in the image portion of the menu. If this does not fix the issue, then your convergence chip might be on it's last leg.

Green Screen


If set displays intermittent green outlines around images, check DVI cable attached to DMD board from digital board. Poor connections on the DVI jack on the DMD board can cause the intermittent symptom. Pull up slightly on the body of the DVI cable connector and check video. Replace DMD board as necessary.

Samsung HCM5525W TV red blue outlines on images


The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
