Re: Panasonic TH-37PH9UK plasma half screen picture

Ahh gotcha ... I was totally confused there and wondered what the heck does that have to do with power.

I don't suppose you know what the DA board does on this set? In my troubleshooting research, I've sometimes seen reference to a DG board and wondered if my DA board is the equivalent.

Thanks again everyone for your continued feedback and support.

Re: Panasonic TH-37PH9UK plasma half screen picture

Well that was interesting ... When I completely remove the flat ribbon connecting the D-board to the C2 board (if that was what you were suggesting), I don't even get the red LED light on the front of the set. Like there's no power. I hear the double click when I press the power button on the set, but nothing happens when I press "on" on the remote. No picture, no LED light.

Re: Panasonic TH-37PH9UK plasma half screen picture

I'm sorry, what do you mean by "top ribbon connector"? Ribbon going from D-board to C2 buffer board?...

Re: Panasonic TH-37PH9UK plasma half screen picture

I don't think I expressed my question very well ...

I meant, regardless of whether or not a ribbon is bad, shouldn't the image have that same rainbow vertical bar as the other disconnected ribbon? Since it's disconnected??

Re: Panasonic TH-37PH9UK plasma half screen picture

Hey I was just thinking ... if the ic on the ribbon is indeed bad, shouldn't the image change when I disconnect the ribbon? (Meaning, I'm removing something bad from the equation, so shouldn't I see something different?)

Like, when I disconnect a good ribbon from the good half of the screen, I get the rainbow bar as in the pic below. If the image is unaffected whether or not a supposedly bad ic is connected, that makes me think it's not the ribbon then and something is just not reaching that C2 board?...

Re: Panasonic TH-37PH9UK plasma half screen picture

So then all 4 ribbon cables (not just the 1 warped one) on that half side went bad when I was futzing with the chromecast dongle?? Gah.

Thanks for your help, though, jason!

Re: Panasonic TH-37PH9UK plasma half screen picture

When I disconnect the ribbon cable completely (not screwed in, not in coupler), I get white bar on the part of the screen aligned with that ribbon. When it's screwed in, but with the coupler not locked (I did this accidentally one time), I get a bar of rainbow colored snow....

Re: Panasonic TH-37PH9UK plasma half screen picture

@jasonr2000 -- hey thanks for the quick response. You had the 42" model? Nice! Yeah, these plasmas had beautiful picture and contrast ... 'tis a shame really. I think I'm approaching the acceptance phase. heh

@ReeceyBurger123 -- hi there! I've re-seated every ribbon and couplers more than I can count, granted just on the C1, C2, DA, and D-boards. I'm attaching pics of the boards (and the slightly warped panel ribbon at the far right) in case you'd like to take a lookie. Much appreciated!...

Panasonic TH-37PH9UK plasma half screen picture

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...
