SOURCE: LG TV - TV Guide Function Stuck
I have the same issue on an LG TV. The TV Guide is completely black with a small picture in the corner. It's as if the software is no longer working.
SOURCE: 42" LG Plasma tv, no picture - black screen, but have sound.
Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.
SOURCE: LG RU-42PX10C Plasma TV picture had colored lines & went black...
This will be your Y SUSTAIN board on the left hand side when you take the back off.
Plenty available on ebay, Very easy fix
SOURCE: loud pop...LG Model 50PQ30-UA Standby light blinks on/off

Please let me know how many times it blinks in between each pause so that I can tell you what the problem is.
