Question about LG 60PZ750 60 in. 3D HD-Ready Plasma TV
The led on the Main Logic Control Board (EAX63989001) is consistently flashing with 2 long flashes, 1 short flash, a short delay, then another short flash.
This is a code for a power supply shut down.

SOURCE: LG LED model# 47LB5800-UG. Black screen, full screen flashes every few seconds. Audio OK. LEDs appear to be lit when screen flashes. Sounds like LED driver or inverted board and/or connecting cable?
