Question about Hitachi 53UWX10B 53" Rear Projection Television
In the service convergence mode, I can line up everything but red. The red would adjust at first, but not much. Now when I enter the service mode the red lines come on, then fade and disappear.
Should I replace the convergence board (Samsung BP95-00415C) or should I be working on the ICs STK394-250 (B4F17 and B4F19 on top of ICs)? If it is the ICs what fuses should I be replacing also? I'd rather not replace the enitre board >.< I'm a poor college student.
I can email the service manual with circuit diagrams if needed.
There is a defaut I c drive how can i fix that

Try resoldering the pins on the ICs first. If that fails to resolve the problem, change the IC responsible for RED. You should be able to determine that from the service manual. In that area you should also see either fuses or low valued resistors that feed the STKs. Check those as well.
Let me know if you need further info.
