Projection TV sets have two very common problems listed below.

Problem #1) 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. 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 more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

On our rca hdtv model # R52WH77.. the tv is having like a 3d look on it and has a bow in the picture.. we bought the convergance repair kit from tvrepairworld.com and replaced the 2 parts it gives us.. ...


have you reset the convergence parameters after installing the kit to fix the option? Usually you will need to reset the defaults to get the outer edges back in alignment.

My 57hx81 has a slight concave bow in the middle top to bottom


Sounds like a problem in the vertical sweep circuit. Check voltages to your convergence ICs. If they are  not to spec then look for bad fuses and capacitors on the power board. These will throw off the DC voltage to the convergence chips causing the bow effect. I've had a single bad pico fuse ($1) cause this symptom.

Check your screen. I have the same problem with mine. If the screen has a ripple in it, it could give the same effect.

Bow like image


You likely have bad convergence output ic's type #STK392-570.  These can be purchased at UED 800-648-6657.  You will need to remove the board they are mounted on to be able to usolder the old ones and resolder the new ones.  These will be mounted on heat sinks.
