Question about Samsung HC-P4752W 47" Rear Projection HDTV-Ready Television
I have gone into the service mode and can move all colors on the grid in all directions except for blue up and down. This problem came out of no where and now i have blue shadows around most letter at the top and bottom of the screen. The blue arcs up from the bottom of the screen and arcs down from the top. Again you can not adjust blue in the grid up and down. I have seen posts about changing the convergence board? Any thoughts?
Sure sounds like convergance problem
Convergence amp ic bad

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.
