The fault can be on the Ysus,Xsu,or buffer boards you need to takeit to a repair shop for diagnosis

Sounds like you've had a failure of a part in the electronics. Plasma TVs use pretty high voltages (like the old picture-tube models) and parts can get fried over time. You'll need to have your Panasonic serviced by a qualified technician. Don't try to do it yourself -- high voltages, remember?

Check the tcons connections ( both flex cables and also the LVDS cable) if that doesnt solve it would suspect the Tcon as being defective. For further assistance please respond to this same post.

Two issues come to mind on LCD/LED TVs with a blank screen. First and foremost, unplug it from the power source for a few minutes, then plug it back in and power on to see if your problem has gone away. If not, then the easiest way to diagnose the problem is to power on your TV in a pitch black room (or drape a thick blanket over it and peek underneath at the screen while it's on)... we want to see if the backlights are working or not. If the screen looks like it's 'lit up' with a dark gray tint to it, then we have backlight and there is another problem. If no backlight, then your set has a bad backlight inverter. In either case, this will require parts replacement. Panasonic is very tight with who they will sell their parts to, unlike other manufacturers and usually require authorization from a technician before selling them.

This is caused by a defective DMD Board

I had the same issue. I could get the tv to work intermittantly by pressing on the boards while playing. This points to bad solder joint, so I resoldered every molex plug connector, and it nows works like a charm.

YOU NEED THE RIGHT REMOTE.

Most likly the signal connector is loose or dirty. (input) this would cause the red, gree, blue or a combination to not be connected.

I am also having problems with the same year and model number panasonic, it is at the repair shop now. I think it is a lemon tv. won't buy panasonics anymore. Tried all the fixes recommended by panasonic. It happens after the tv is on for longer than 1/2 hour. It happens with dvds and different hook ups. my samsung is fine on all the same connections.
