IC's for JVC AV-48WP30

I saw in another thread that you would help find someone some IC's for their JVC tv. I want to make the repair on mine but I cant find the right IC. Can you please let me know which one to use. I am a college student so I dont have tons of money but I dont want one thats gonna break in a year if you know what I mean. I would really appreciate this so much.

Thanks in advance

You need two STK392-110 convergence ICs. You can get them at the following link with free instructions on how to replace them. They actually have the repair kit for your model which contains both convergence ICs and the convergence resistors.
Heres the link.

JVC AV-48WP30 48 in. Rear... Problem


Your convergence I.C's ( integrated circuits ) Have failed. Replace Both I.C's with Stk392-150's. The unit is equipped with 110's. These are large IC's pn the convergence board located near the front of the unit. You need soldering/desoldering experience to do this job. I would recommend seeking professional assistance.

Convergence always needs tweaking


This sounds to me as if you have a defective convergence output IC, whose gain is now sensitive to heat. As the IC gets warm, the gain changes and you see the colors separate. If you do not want to do any soldering then have the IC replaced by someone with experience in convergence circuits.

Convergence problem?


Not unless the Tv sneaking some kegerator juice while your not there??LOL It sounds like a Main b+ filter or possibly the convergence IC and is not user serviceable. With all the hi-voltage inside these sets its best for you and the set to call in a proffesional to do this type of repair. Sorry i couldnt assist you more with this repair.
