Question about RCA R56WH76 Projection Television
Unless you are an experienced repairer I suggest not doing STK ICs replacement by yourself.
The replacement is a precision job, and if you do not do it properly you can damage the TV.
An easier repair can be done replacing the whole convergence board.
Do the repair at your risk, follow all safety rules and leave the TV unplugged few hours before doing repairs. The capacitors inside the TV can release high voltage discharges even when power is unplugged.
