PN64D8000 screen goes blank once a day
Our 2011, PN64D8000 screen goes blank once a day. The red standby light is off, and we can still adjust the volume. If we unplug it, after an hour or so, we can plug it in and the screen works.
The TV is four and a half years old and this seems to happen to other D8000 at this age. I noticed that when the unit is normal, a green LED on the back flashes once per second. When the screen fails, the LED is on for about 3 seconds and off for 1.
The TV has always been on a surge protector and the house has a lightening protector on the main CB panel. I updated the firmware to 1031.1 and did a service reset with no luck.
Precision Television, Inc. will be out next week ($135 to take a look) On the phone they said that the screen needs replacing. The screen is perfect when it works. I have input the ISF calibration numbers again and it looks the same.
Other members on this thread describe a board issue. Does anyone have an idea of what the flashing green LED signifies?
