The convergence on my JVC AV-48WP30 always needs adjusting. After powering on and waiting 5 min or so, I will adjust it the best that I can. All 9 positions can be adjusted, mostly. The Red gun in position 9 is a bit rotated clockwise so never gets totally to white in that position. After powered on for a while I see the color separation and have to adjust it again. This happens every 30 - 60 minutes. The TV is almost 5 years old. I have electronics training but would rather not do any soldering. What might the problem be and is there anything that I can do to lessen the amount of adjustments that are needed.

Re: 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.

Ur tv still have convergence problems,if u can't reajust manually crosses or auto convergence.U must have 2 not just 1 STK convergence ICS to be replaced,all the resistors must test by the Ohm mulitimeter to the right resistance of the resistor's and replace them as require.
you will need to install a convergence repair kit. You can get the convergence repair kit for your model at www.tvrepairworld.com which also contains the CD with step by step instructions for the repair.
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.
it looks like theres a wave in the top of my screen on my jvc av-48wp30 not sure but i think it has something to do with the bulbs because the projection mirror wasfine and all wires seemed to be hooked up properly.. can you help? tell me where i can find the bulbs to replace them?
There might be some features that the universal remotes aren't able to do. To perform the convergence alignment you should have the original remote.
Do you have the user manual or service manual?
The service manual will explain this process better.
