Re: LG 42PG20 - has sound - no picture
Things are going better, thanks!
I have not tried the test patterns; the panel does not glow at all in a pitch-dark room. I get the loud relay click when plugging in the power cable and turning it on/off, but there is no light from the panel at all.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

LG 42PG20 - has sound - no picture
Currently I'm troubleshooting an LG 42PG20 plasma television.
I'm able to confirm that sound works through the three HDMI ports, connected to my PC graphics card.
I hear a "click" when the TV is plugged in, when it is turned on, and again when the TV is turned off. The red standby light on the front of the TV turns blue when "on".
At no point does the panel energize/prime - I have blackout curtains in my room, and cannot see any glow whatsoever coming from the panel while testing.
Initially I assumed the problem...
