    Replaced IC's, pico fuse in "D" board, and a pico in the "G" board the T.V. (KP-46twt510) was restored to its normal function, it looks great. Now I have a different problem? The set stays on for about 5min or so and then I lose sound and video, if I tun it off and turn it back on it returns to normal, but it does it once again, but it happens much quicker every time. Could it been something I did wrong or left unplugged.. otherwise it looks better than ever! The set never actually goes off it just seems off. Blank or darken screen.. no sound and it will return to normal after I tun it off and turn it back on. I've also notice that if I push guide on the remote it restores sound for a fraction of a second. Any help out there with this issue..

    thanks,

    Rod

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.
Solution #1

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.

It is possible it is the board, but that would be rare. If you have the service manual, follow the supply voltage lines. If the entire board was changed, the onboard fuses should be good. Check for 24V supplied to the board.

Keep us posted.

    The problem is not the picture....It's green faded lines going across the screen in a slight ark....
    once in a while the whiol screen will light up bright green like a flash and dissapear.

Convergnce sony kp65wv600


You can get replacement Ics at the following link which provides free instructions. I would recomend replacing the 4.7 ohm 1/2 watt resistors along with the two STK392-560 Ics as the resistors can get weak over time and that can lead to premature IC failure. Heres the link.
