My LG DU-50PX10 Plasma also went bang, then dark & silent.
I'm pretty sure from other posts that it is my Y circuit/sustain board - one of the capacitors. But I note there is a small subpanel on the back w circuitry beneath. I'm hoping it is located in that smaller section, otherwise the whole back panel needs to come off I bet. Can anyone confirm where it's located? Any photos ( LG DU-50PX10 Plasma)
