Hi everyone, having issues with my plasma tv. It has sound but the display is totally black, on occasion I would see specs of multicolored on some parts of the screen. Its like little fireworks going off but it rarely happens. On the control board has a group of LEDs, on the far right its blinking constantly while the one next to it on the right is constantly on. The boards inside are made from LG. The volume, input, and channel buttons work. If anyone got any info let me know. Thanks
