Unless you can solder and use a meter then yes you need to call a tech, this repair should run somewhere from $300-$500. Let me know if you need more info

My tv has lots of red and green. Faces are shadowed by a red outline. It occurs on all channels and dvd.


If problem does not fix by flash focus/ convergence adjustment in Menu then replace convergence output ICs on D board of tv that sounds defective and causing problem.
Comvergence output ICs replacement requires soldering work with proper tools and electronics knowledge/ experience, call local tech if you have no experience.

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.

Concave tv screen colors distorted just had tv repaired one year ago for same problem


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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 from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Lcd sharp tv flashing green light


Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

Picture distortion


This should cost you about 300 to 400 bucks to repair. If the service wants more, they are ripping you off. The convergence IC's are whats bad in this set and both of them cost less the 30 bucks. Good Luck
