How to remove yellow color in center of tv screen


first try cleaning all lenses & mirrors. Considering the age of unit you may need to replace cooling fluid in front of each CRT. I highly recommend a professional to do this if you consider it economically feasible. Possibly 1 or more CRT weak.

Bluish screen whites really bright background really dark it was fine untill some one messed with the color


Their is a CRT fluid that keeps the three lenses cool ontop of the tubes. The fluid goes bad after a few years and causes what you describe.

I have a sonny rear proction tv its very foggy the piture


Three things you need to do:

1) Take the back cover off and clean the:
a) Mirror with glass cleaner
b) The dust that collected on top of the CRT lenses


2) With tv unplugged, use a flashlight and look down the lense of the blue, green CRTs. There is fluid in there. If the fluid is not clear, then it needs to be replaced and the tv re-aligned. Not recommended for anyone without experience.

Cloudy fluid is typically indicated by a foggy picture. THis is assuming you have a standard 3 CRT rear projection TV.

I have a 47" rear


This is usually due to a leaking CRT. Or picture tube oxidation in the cooling liquid. Definatly not a job to be performed in the home. The cooling liquid needs to be changed in all three picture tubes. Cleaned inside the jugs and replacement gaskets. Gennerally about 60 to 85 dollars each.
often, the fluid leaks onto the power supply or sweep module and causes other problems.

The blue will not converge, how can I manually do it? The blue appears to be showing bottom left corner below the screen, like it got moved.


I had the same problem but it wouldn't converge on the whole right side of the screen. I fixed my problem by taking off the speaker cover, removing the 3 allen 7/64" screws from the front of the bottom of the button pannel, then removing the 4 scew from the back of the pannel (2 on each side), and the button pannel should drop down. With the power on I cleaned the 3 projection lenses with many qtips dipped in alcohol. I left the TV on so I could see if there was any streaking on the lenses (streaking means it is still dirty). Once they were all clean and I put the button pannel back on, I went to the menu and ran the autoconvergence function. Now my picture is so clean. Good Luck.

Hazy yellow spot in the left lower corner of the screen


It could be a cob web inside the tv or something laying on one of the guns, like a dead bug. If it's a cob web, you should be able to move the tv a little side to side and see it change from the moving air current. I would remove the back and vacuum off the lenses of the guns and look for cob webs. It's safe to touch and clean the lenses, just don't touch any electronics.If this doesn't fix it, it's probably fluid starting to cloud up in the guns or IC chip problems.

Mitsubishi ws65613 no picture or sound, blue screen only


Good Day;
Blue screen that has gotten worse over the past few days, I would suspect fluid on your signal board.
The three CRT's in the TV has coolant that tries to keep them cool but they have a problem with the 'glycol' leaking out of it's chamber.
Take speaker grill off, remove panel and look on the right side of opening. Look for fluid on the board, shinny substance, it's hard to see so look closely. That is the most common problem.
2&3 are the CRT's or the CRT's drive circuit.
Good Luck, Day,let me know, Big Irish.

Blue lens works, but has a weak projection compared to the green and red lens


The most common problem I have seen with these Samsung projo units is the blue CRT (picture tube) failing. They usually form algae on the face of the CRT which means replacement of the CRT or rebuilding it by a CRT rebuilding company. I wouldn't suggest the novice to pull the CRT out because if the wrong mouting screws are pulled you will spill out the cooling fluid within the face of the CRT and that will cause more problems.
