I recently got a 42LG30 that constantly power cycles. The TV will turn on, stay on for about 2 seconds, turn off, turn back on, and loop like that. Voltages being output at the power supply connectors look alright. Whenever I unplug the power button/IR receiver board the TV will stay on but I am unable to control it. Having the side buttons plugged into the power button/IR board doesn't make any difference to the power cycling. Is this board a common problem in LG TVs, or is the mainboard actually causing the problem somehow?
I may be able to pull another of these boards from an identical TV that I already fixed and resold (bad power supply) and I also see that a member has one of these TVs available to part out on here, plus one on eBay.
