Question about JVC AV-56WP30 56" Rear Projection Television

1 Answer

JVC AV-48WP74 lines pulled towards middle

I have read the site, thanks to everyone here. Ordered 2 STK-110's from Electronix. Replaced them; the red squiggly lines coming down from the top disappeared, so some progress. Then I thought adjusting the lens in the back would take care of the lines pulled to the middle..>>WRONG<<<. So I am reading this site, and I keep hearing about some low ohm resistors but no info on what they are or where they are located. No product specs I mean. All 3 lines or colors seem to be affected. If somebody can tell me where they are, and what they are, maybe I can order them and replace them. Thanks to everyone for your help.

I will be doing this same repair for a customer in the next two or 3 days, Without looking at it, I believe the resistors are orange or pink in color and labeled 3.9 ohm, but i will get back to you after I pull the board and have it in my hand.

Sits on soldier stand, and will take a good soldiering job to attach. I replaced both since they are only $12 for two of the STK chips.

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.

no you did the right move but now you align the new pc board ,try to get the service in to enter the convergence alignment section,on most jvc;s it sleep timer ,disply&video status to enter try it but if your not sure of that you can perform the alignment ask a tech to do it. on the remote certain keys do special functions and you need to know what they do or you might make it worse.

JVC MODEL # AV-48WP74 48 IN. BIGSCREEN TV.


I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce
