Good Day, trinityfaith;;
The RCA is very different then most TV's. It could be one of four boards that's causing this. There is no common one. Please call a Factory Service Center and have give you an estimateb4 repair. Sorry, but Good Luck, big IRISH. PS You are looking at a 4 to $550.00 repair.

My sansui rear projection tv's picture is concave with convergence problem also how can i fix it


The convergence can become unstable if you have a failing colour wheel if a dlp set. the same thing can happen if your lamps is beginning to fail the poor frequency of light from bulb disrupts picture. Convergence is usually done by entering service technician code into set through the remote and entering the engineering sub menu and if you don't know what your doing or have a colour pattern generator you could make things considerably worse .

Do a static convergence on your set. You should be able to go into the main menu and scroll down to picture and press select. Then go to convergence and press select. A white cross will appear use on screen direction to line up all the colour crosses behind thie white cross untill they all appear white. Then press continue and you will see several white crosses do the same for each one of these crosses. this should solve your problem. If not u have some bad convergence chips

Picture looks concave ,mostly yellow,and double vision on words


Remove unshielded speakers or other metallic objects near the TV. It can cause picture distortion.
  1. Tune the TV to channel or cable program.
  2. Run the TV for at least 30 minutes.
  3. Press FLASH FOCUS on the front panel of the TV.
  4. A cross pattern appears and FLASH FOCUS begins to
    work. The adjustment is completed when the cross pattern becomes white and you are returned to the program you were watching.
You cannot perform any other functions until FLASH FOCUS has
completed its cycle. If you perform any other operation while FLASH FOCUS is in progress, FLASH FOCUS operation is canceled.

Picture on projection screen is concave in the middle


This set does not use IC's for convergence. Most other brands do use IC's.They use individual transistors in this one and honestly I don't remember ever seeing these go bad. Normally it is the power supply that runs the convergence transistors or more commonly known as the convergence board. It gets pretty technical with this type of problem. Have a repair shop check it out for you and avoid the headache. Thanks

Mitsubishi VS-50501A convergence problem. The image looks like a bow tie and the convergence will not align. This TV only has manual convergence. I already replace the STK391-020 ICs, it has 3 of them....


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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture
