Question about Hitachi 53UDX10B 53" Rear Projection Television
I used the MagicFocus for the RGB, the green and blue are focused correctly, but I can't allign the red for the life of me. Also, there seems to be a huge pincusion effect on the right side of the screen. The mirror is clean, all three tubes are clean, and the screen (back and front) is clean. I don't know how to get rid of the pincusion, or if I would even be able to.
Part number HI2003191 Generic # STK4274 Anywhere from 10-30 bucks. Looks like a comb so you better bring your A game soldering skills.

One of your convergence IC's is most likely the problem. Check the IC's for cold solder joints and also feel each heat sink the Ic is attached to, the one that is running the hottest is most likely the bad IC. Also check resistors in front of the IC's for burnt, discolored, changed values.
