LG 60pa6550 plasma tv display issue

Hello I have a LG60pa6550 Plasma TV. The TV will work fine and I can leave it on for 24 hours or it seems indefinitely without issue. I can also turn the tv off and back on without issue if done within a short period of time. However If the TV is off for a few hours the screen will not display for 24+ hours. I have both left tv unplugged and plugged in but off and I still have to wait over 24+ hours for the tv screen to display again. I opened the back and could not find any bulged capacitors. When the tv is turned on, I can hear sound but no display. At times if I do not wait the sufficient time, the tv will display for a few minutes but turns itself off /standby mode, when I press power again the tv will turn on and I will have sound but no display and simply have to wait with tv off for 24+ hours for it to work normally. When I unplug the television and wait 24+ and plug it back, at times the Tv panel will glow for about a second, when this occurs the tv works fine. If I plug it back in and the panel does not glow for a second the tv will not display.
