Double images on screen


IT SOUNDS LIKE A PINCUSHION PROBLEM. IN MOST CASES IT IS DUE TO CAPACITORS GOING BAD ON THE BOARD. OTHER TIMES SOME TV'S HAVE LARGE MICROCHIPS THAT RUN THE PINCUSHION AND COLOR SYNC. HOPE THAT HELPS.

You have defective Convergence IC's. It's best to have a service company verify and do the repair if you wish. Normally runs about $250.00

Double image


In all probability you need to have the convergence amplifiers replaced. A very common problem with all projection sets.

Double Image Red and Green


Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

48 inch toshiba with color alingment problem


Hello:

Thanks for this forum.

I have a Toshiba 48" rear projection TV which started to show red and green lines on the left side of the screen and have also started affecting the left-hand focus of the image shown on the screen. I have had this TV for 14 years and had a projection adjustment done once before.

Thank you in advance for your assistance.
