Same problem.. JVC 48" TV. Can you email me the relevant portions of the service manual also? had my TV for four years and would like to see if we can replace the parts ourself if possible. We're up in a rural area, hard to get a tech out here.

Is it like a ghost red image. It's probably the STK392-110 convergence correction chip on the convergence board There are two of them the one the red one id right behind the input for the red gun I think it's U804. It's a 18 pin desolder and resolder once you get the board out.

I seem to be having a similar problem with the same set(surprise surprise). I turned mine on yesterday and the convergence was way off everywhere but in the center of the screen. Also, there are fine horizontal lines across the top that have a 'wave' effect to them. When I try to set the convergence in the setup, the middle is fine, the bottom is off to the left, and the top is slanted towards the right and fluctuates as you are looking at it. Would this be a convergence board or STK problem as well? Much Appreciated, Shaun

HI,I HAD THIS TYPE OF PROBLEMS WITH SONY AND OTHER MAKES.SOLVE THE PROBLEM BY REPLACING THE STK AMPLIFIER ON THE CONVERGANCE BRD. GOOD LUCK
