JVC AV-48WP74 48 IN

My TV has a red shadow or a double red vision. I see that other people have the same problem. What part do I need? Is it the same as the 56 IN? STK 392-110? Do I need two or just one?

You will need two STK 392-110 ICs. They are located in the front of the TV. remove the speaker grille and then the small access panel and you will see the convergence board it has two Black heat sinks the ICs are mounted there. You can get replacement ICs with free shipping and free instalation instructions at the following Link.

You probly have a convergence cicuit failure. Replacing the convergencr IC's will probly fix it.
I recommend a professional repairman to
do it though. Particularly if it needs further adjustments after the IC's are replaced.

If the images are different colors (red,green,blue) then the convergence has diverged. Some TV allow re-convergence through the menu screen, older sets my need to be physically adjusted (aimed) to clear this up. a strong knock to the TV may have cause this.

You have an convergence problem, There are 2 IC's that go bad and a few resisters that can change value. If you flip the board with the Chips inspect the pins for cold solder joints. The IC's can be purchased from matelectronics
