Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

Blue and green halo's on the picture screen.

This just happened, It did not start out and get worse. Could this be one of the bulbs in the back? And if so should we replace them all?

Sounds like a Convergence issue. This may be just a blown fuse that you may have to remove and solder a new one in or it could be a chip with heat sink on it. You will see like a brown spot on the chip. You may also need to resolder some bad spots do to overheating and you can spot these fairly easy.

After lamp replacement, why is picture still green?


it seems like the green was not defective before you replaced the green. remove the red =no change in the screen color, that could be bad. put back red, then remove blue=screen color changed, blue is good, hope you got the idea.

My Hitachi LCD rear projection TV has blue color in left corner


It is most likely the tube going out. Find some one to replace the tube if the TV is fairly new other wise it is going to be a trend. One tube now and another.. and so on. Ride it out as long as you can then go for an upgrade

Double Blue Halo Effect and Blurry Blue Picture


thats a problem with the Blue CRTs coolant needing replacement. If you look directly into the blue and green CRTs while its playing you should notice a bunch of crud inside the lens indicating that the coolant needs replacement. You can get the coolant replacement kit for a phillips at the following link which includes the coolant and instructions

Philips - Magnavox Model # 9P6034 C103 Picture problems? Please Help


1 5 oz bottle should be enough for each tube. The small picture is caused by bad opto-couplers on the large signal board. Let me know if you need more info on the couplers and where to get them

No. your problem is related to the coolant in the green CRT has congealed with bacteria and needs to be changed. Thats what causes the halos and general poor picture and color quality. The blue should be changed also. The red for some reason doesnt seem to be affected by the bacteria problem. This is a common problem that happens with all projection TVs phillips and magnavox TVs

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif 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
