Hi there, please be gentle. I'm no repair expert at all, with the extent of my experience fiddling with electronics building a desktop computer and replacing a TiVo hard drive. I hope you kind folks can help fix my beloved Panasonic TH-37PH9UK plasma.
What happened: I was watching football when I decided to watch something on Netflix. Chromecast (hooked up to the back of a Yamaha receiver) won't seem to cast onto the tv so I reset the dongle by unplugging/plugging back into the hdmi slot and also unplugging from the power outlet.
Well I must've shorted something as next thing I saw were colored vertical bars going across (appearing on) the screen from left to right. They then stop and what's left are the black and white vertical bars on the left half of the screen.
What I've done: From the service manual for this exact model (and actually I've looked at other manuals, too) and everything I can find on the internet, the fault seems to be either the C2 buffer board, the D-board, or the panel itself.
I did the internal test patterns and same thing – picture is perfect on the right half screen, with the black and white vertical bars on the left.
When I disconnect the D5 connector from the D-board, I only get white on the right half of screen.
I've of course already replaced the C2 buffer board and the D-board, but to no avail.
I've looked at the mylar ribbons (corresponding to the onscreen vertical bars) attached to the panel closely, but nothing particularly weird. (Although the ribbon at the far end is not as flat/with very, very slight warp compared to the other ones.)
I know I'm in total denial that it's the panel but I'm stubborn and want to know I've tried every possible solution. So I guess I'm depending on you guys for a genius idea or to pronounce time of death.
Thanks so much in advance.
