Question about Mitsubishi WS-65905 65" Rear Projection Television

1 Answer

Tv powers on, has sound but no picture. All three lights are working & will show the input display but distorted. I would like to do the repair myself but am not sure if this is a convergence issue or something else. Any help would be greatly appreciated.

Even if a convergence problem exists you should still have a picture, a bad one but a picture----call the menu up with the Mitsubishi remote and select convergence and then advanced---a grid of lines will appear in green---got dramatic red and blue showing and you have a convergence issue.


Do that first----presuming no hookup is ok (try a dvd player) the set does have the OPTION menu(can tell you how to get there) that is based on a 4 digit number code--may have that for this model or not).

It will not correct any convergence problems but will do a hard reset of the set back to factory original.

Let me know what you find---it sounds like 2 problems exist.

Your problem is one and or 2 differant problems. The power regulator could have went bad because of the convergence IC have shorted. Seen this a thousand(easy that!)Times. All parts in this set are soldered in and are not user serviceable. look in your owners manual or call 800-332-2119 to get an authorized servicer to come and look at your problem . I wish i could tell you what to replace but theres the Extreme Hi voltage inside these sets even when they are not plugged in .. Good Luck

No picture


Did you check whether there is any option to put the display off in the remote or on the TV? The problem of no video can be due to backlight off (if it is an LCD) and CRT filament not glowing if it is a CRT TV. If it is an LCD TV, show a torch light in front of the screen when the program is running and see whether you can view the pictures. If you can, then the CFL (or LED) inside the display is not getting power or it is fused off. Might then require further investigation on secondary power supply (inverter etc.)

Olevia 242 TV.... No picture or sound!!!


A blue screen usually is present if no signal is connected to the set---hook a DVD up to one of the rear inputs--select that input and see if have picture and sound.

If that works connect cable or antenna to set and select that input

NO signal is like no gas in car---it will not run.

Mistubishi Convergence/video display problem


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,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
