Question about Mitsubishi VS-45607 45" Rear Projection Television

1 Answer

Picture has greenish tint that I can't adjust out

Techman, I replace the red convergence chip in my Mitsubishi VS-45VA1 a few months ago. All was well until recently when the color started to change, getting a greenish tint that I can not correct. The image looks washed out and anything that should appear black is like a muddy green. Hope this description is accurate enough to help to identify the problem. Thanks DRA

There is a crt drive problem and you can isolate it by unpluggin g the set, removing the green crt socket, in the middle of the three tubes is the green tube by the way, remove one of the other tubes and switching the crt sockets and turn it on. If the set is still greenish, then the green crt is bad and needs replacement, if another color is primart, then it is going to be the green crt drive circuit and is going to need to be serviced. Good Luck

Mitsubishi VS-50609 - Red convergence is way off, suddenly


You have a bad ground on a convergence IC. You will have to carefully pull this board out and resolder the pins. If this does not solve the problem you will have to replace the ICs. I have saved a few of these TVs with just a resolder job. Thanks for asking!

Hour glass cannot adjust red horizontal convergence


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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Toshiba Rear Projection TV picture color is now a greenish hue


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)

Mitsubishi tv problem


im assumiong you checked the tint in the menu options. if not go check it. other wise it sounds like you have a weak tube, or you do not know how to adjust the screen brightness. this is how i adjust the brightness (you dont need to touch the focus). turn the red up until your whole screen is tinted red, then do the same with the blue and the green. then go through each one and turn down just a little till your pic darkens a little. good luck
