    If you mean FLASH FOCUS button, Yes but didn't help much.

  • abaxi Feb 22, 2008

    I don't think this TV has any focus menu or convergence related option in menu. even the user guide talks only about FLASH FOCUS button for convergence. If you could point me to any other way to set convergence via menu then it would be a big help. btw, when I try to get in service menu (display, 5, vol-, power) then it shows "1" for #5 and #9. rest of the numbers are "0". Red light in front of the TV blinks 5 times. If this is indicating anything for diagnostics. Anyway Thanks for your help.

The colors are separated. Images are blurry and


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Cannot converge colors on screen


This happens when convergence out ICs become defective.
Replace convergence ICs on D board to get correct picture. This qualified TV tech job.

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.

Solution :


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 note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.

Arjun
