Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

Convergence no adjustment

On this mitsubishi 40" vs-430ca projection tv I have changed the convergence chips and had no change there is no convergence adjustment function happening with the alignment buttons .trying to set the convergence has no effect. there is still a picture and sound but the picture has the top /bottom coloured bows I have not changed any resistors in the convergence circuit because I have no clue which resistors go bad . On my 60" zenith I fixed it with an r 3243 resistor on the smps module . could a person in the know about which resistors (and their values) go south in a mitsubishi set please let me know the rundown list and the approx placement in the set.

There are black in color circuit protectors in the set that have blown because of the bad convergence IC's. You will need to measure the voltages on the ICs and make sure you have the correct plus and minus voltages. There should be about + and - 24 volts on each IC. I'm afraid the only way you will know what voltage are what and where they should be would be to get a service manual. i am sorry i do not have this model to share with you. Good Luck.

I have a 12 yr old Mitsubishi projection tv model vs 60607 with a red/blue convergence problem. Can it be fixed?


It should be fixable----this model uses two of the STK-392-110 chips for convergence.

If it adjusts but will not remember the adjustments either a bad solder connection on one of the chips or a problem with the DCM---digital convergence module which stores adjustments.

Adjustments in customer menu may not be being stored--

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

I have a Mitsubishi Rear Projection tv (vs-50705). The picture shows a concave image on the top and bottom of screen and the edges go off the screen. I have red blue and green ghost images on the screen...


Well, you did the right first step. However, when the convergence outputs toast up they sometimes cause other problems. First would be the fuses that supply them voltage. These are pico fuses back in the power supply. Second would be open supply resistors that have opened up because of the excessive current draw caused by the whacked out convergence amps. When changing the outputs doesn't solve the problem it takes the repair out of the realm of the do-it-yourselfer. My recommendation is to let a professional take over.

Mitsubishi Rear Projection makes funny shapes on Green and Blue


Your Green and Blue horizontal video amplifiers have collapsed: try using a freon cold spray on these chips as this occurs when the heatsink grease dries up on the HVA chips and, causes an overheat condition; if you have an oscilloscope monitor the vert drive as well.
