Projection sets have two very common problems outlined below.

The first common problem is convergence

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

My tv went from being normal to crazy in the matter of a couple of minutes. It appears as if the picture is bowed. And you can see the words comcast 4 times on the screen all in different colors.


Go to Menu then setup,If you do not see Convergence on the menu then problem is in the Deflection Board,Located on the bottom Left hand side.
Over on the Right hand side of the FBT flyback transfomer is 3 Fuses in a Roll FL231
they will be small rectrangler looking caps but are Fuses it will be the one in the Middle 0.06amps.
Mats Electronics 1-800-628-1118 you can take a pair of needle nose plyers and pull Top OFF of Fuses. You will also need to resolder all the pinns on the FBT.

BenQ MP610 Video Projector Shadow


This model is now out of production. It was sold as one of the bottom end of the "DLP" projectors. It's basically a "good cheap" model using a 1.5cm DLP mirror. And being as such, over the year the "thermal cycling" has most likely caused the alignment to shift. It could have collect some dirt in a quadrant of the lens too. That's possible too. Being a manual focus, there is at least no "auto focus mechanism" to worry about. That can be a pain to adjust. You could fix this yourself with some luck. It either has three screws to adjust or it has an ellipictal ring arraignment and you'll need a two correct size spanner wrenches. If it was in front of me I could tell you right away. In any event, if you turn either one of the screws the wrong way it can get worst or if you don't have the correct spanner wrench to adjust it either you can be more trouble. Plus you need to do this with a light source "on" so you can see the effect. Your best choice in this case is to go to a camera repair shop. One that doesn't send their repairs out if you can. (you have more control over the repair) It's an "adjustment and cleaning" and shouldn't be that expensive to do. Please let me know the results when you decide.

The top of the screen is slanted while the sides of screen and bottom are even, causing the right hand side of screen to appear smaller than the left. Anyway to fix this?


Sounds like a "keystone" problem. Your projector needs to be oriented to the screen in an exact manner. Manufacturers provide "keystone" correct to adjust for mis-alignment. If proper orientation is impossible, use the keystone correction of the unit to adjust your edges.

Red bow at top left and botton left of screen


Lost of high voltage on the vertical amp was caused the bowing. That was a simple tweak. I'm sorry to tell you that the high voltage adjustments are rather precise and have major interaction with each other. The HV circuit is also used to power low voltage circuits to gain efficiency. If one or more are not within spec, the process to recovery will require bench alignment of the various stages. Seek professional help or consider replacing. Good luck
