I purchased a *slightly* used 50H81. I work for the place that sells it and it was a return from a customer. They had the TV for 3 weeks in which they were experiencing an "intermittent shutdown" of the television. They returned the TV and it went to service. Looking at the documentation, the TV was "resoldered pins 1-6 of IC 2801." Does anyone forsee this as a potential problem? I got an unreal deal on it and the TV is in "new" condition. thanks in advance for your expertise.
