Question about JVC HD-52G886 52" Rear Projection HDTV
The picture even in the "full" aspect mode is too large and both the bottom and top edges are cut-off. This just started to happen. Not sure why. How can I adjust so that the full picture can be seen?
The convergence amps need to be replaced. If you're having a shop do this call around and ask what they charge for repairing the convergence. If you're doing this repair this set uses two stk392-110 Sanyo built amps. You will also need to test and possibly replace one or more of the 1.5 ohm feed resistors in that circuit.
If you're doing this at component level try Acme in Florida for amps and resistors: 1-800-575-9833 http://www.acme-sales.net/index.shtml and if you're doing this at modular level send it to PTS http://www.ptscorp.com/ 1-800-844-7871

More than likely you need to replace your IC's on your convergence board. Im not entirely sure on this model, but it's probably STK392-110. There are a lot of people that recommend that you replace them with STK392-150 to ensure a longer life.

I think that your ICs are ok, What you need to perform is what is called dynamic convergence, This involves using the internal convergence controls to align the outer edges of the screen. I am assuming that the center of the screen is ok? it's just the edges which are misaligned, right? Now for the bad news, this task is not easy in fact the job takes a pro about 6 to 12 hours to do it right. I think you should have a qualified TV technician attempt the static convergence setup followed by the dynamic convergence setup.
I hope this helps,

A projection tv that has color issues is usually due to bad ballast which is attached to color wheel which you should also look at to make sure the colors are not mixed together and wheel is not warped.
