I was given an LG 50pt350 television the other day. When I got it to the house and plugged it in I found that the tv did not come on. I checked for any standby lights but I don't have any in, there is no clicking noise or backlight either. I assumed that the power supply board was the problem so I ordered one and replaced, but still the same. Any assistance would be greatly appreciated thank you

Re: LG 50pt350 plasma tv will not come on
Ok on the connector to the mainboard (the one with the hdmi scart etc)
You should see a pin marked 5vstby.
Do you get 5v
DMM on dc volts, black probe to the tv chassis, red probe pushed into the 5vstby pin.Last edited by Hamie; 03-31-2015, 02:51 PM. -
Re: LG 50pt350 plasma tv will not come on
Ok so when I disconnect the connector from the power supply board to the main board (the one with all the peripheral hookups) the tv clicks and it appears that the back lights come on( screen turns grey). I did not check the voltage yet, does this help any?Comment

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...
