Hi folks,
I've owned my Panasonic TH-42P77U for a year and half and last night it began displaying a 2 to 3cm vertical black bar on right side of screen, runs approximately half way up screen. Right beside it is another 2 to 3cm vertical bar containing digital noise and a rainbow color effect that also runs approximately half way up the screen.
I've posted a picture of the display problem below.
The problem began last night after I hooked up and activated my Comcast HD DVR. The DVR component is a Motorola DCX3400. After the cable signal was activated, the bar with the digital noise and rainbow effect appeared. I should've snapped a shot then too, because it actually looked more severe then the photo I've posted below.
Anyhow, the bar appeared and shortly after that my TV shut off. The small red light beside the power button on my television began blinking. To be precise, the red light blinked 10 times, paused, then another 10 blinks, pause, so on so forth.
My TV wouldn't turn back on. I unplugged everything from my television - every cable attached it. I unplugged power from the wall. I plugged the power back in - tried to reset the TV by holding the power button down. The reset would stop the 10 blinks, but if when pressed the power button, the blinking would start again. At this point, I started to worry that my TV was fried and would never turn back on. I unplugged the power again and decided to sleep on it.
This morning I plugged the power back in and turned the TV on. All the video inputs were still unplugged, but the screen displayed the black bar and color digital noise bar. I then plugged my Comcast HD DVR input back in via HDMI cable and am able to watch television with an issue except for that black bar and color digital noise bar. I should also mention that I'm using a 2-way cable splitter from the wall. One output leads to my cable modem. The other output leads to my HD DVR.
Any thoughts on the cause of this problem and how to solve it would be much appreciated.
