LG plasma tv 50pc3d pinkish coloring, dark display
I'm pretty sure it's the X or y sus. But to be sure I'm posting this issues. I have removed the back and felt both boards heat sinks top ones are warm bottom heat sinks of both boards are cool. TV works, but poor color.

How Do I test the IPM's? Ohms, volts, vs to to v?Comment

Re: LG plasma tv 50pc3d pinkish coloring, dark display
For now, you can just check between Vs and GND of each of the SUS boards... Use ohms mode to find a short, if one exists...Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello,
I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
Opened TV cover & observed foll
a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
How to confirm Y -Buffer board... -
Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
No picture but you hear the TV static (white noise) playing loud and clear.
The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
But it seems they didn't get too far and just left it.
When I first took a look I was amazed at how pristine the inside looked.
Its as if the TV had been in a time capsule.
Caps looked like they were just pulled off the self.
Copper coils had no sign of corrosion on... -
Hello . I have a problem with a samsung plasma tv stuck in bootloop . The TV is Samsung PS51D6900DS plasma smart tv .Need help if anyone have any suggestions
Thanks a lot !! -
I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad...
