Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television
The greens, reds and blues are dragging all over the screen. AT first I was able to fix it using convergence options on the remote. Now it is impossible to line up the different colours. They won'tstayconverged. Do I need to replace something?
Yes you need to replace the two convergence ICs. They are located on a huge aluminum heat sink they have about 16 legs and they will have a number stamped on them such as STK392-110. You can get new ones for about 10.00 each and it takes about a hour to replace them if you can solder. Let me know if you need anymore info.

4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).
The green pattern is fixed. The red and blue patterns are adjusted to
the green pattern. The Red Convergence appears first by default.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
