This may seem like a generic answer, but it's not. Your Power Supply board may have a few failing capacitors. A capacitor will often "fly right" after it warms up a bit. You should stop using it until this problem is resolved. Most often the capacitors are used to filter out "ripple" from the DC voltage it is in circuit with. When the capacitor is weak or failing, the "ripple" or unclean voltage can cause damage to the Y-Sustain board. An easy fix can become a costly repair. I hope this was helpful, best wishes.

My LG 42LC7D tv wont turn on. The green led lights but no picture or sound


There could be several things going on, I would start with having the power supply checked. I've worked on several LG sets from that time frame that all had bad capacitors in the power supply causing all sorts of issues
