I need your help once again group. This is my first LCD TV to fool with, but I suspect troubleshooting the power supply is the same. The set has no standby power, totally dead. I did some initial checking in the supply, but found nothing wrong. Have good B+ on the switching regulator, but even trying to trace the PCB, I can't figure out where the standby power is derived. I have checked almost every component on the PSB and found nothing bad. So, without a schematic, I was hoping someone here has dealt with this type issue on same model or similiar. It's a friends TV and only 6 months old, but he asked me to look at it before doing the warranty thing - story that I didn't want to get details on since it was going to cost him money ($225) to ship for repair. Thanks to all that reply, and yes, if it was my TV, I wouldn't be paying jack, but as I said, I would rather just help him with repairing it. Thanks again group.
