Working on the board below:
Model No. 51EHF_XYM
PCB No. LJ41-10170A
PBA No. LJ92-01867A
There is a short between ground and the Vs pins. I assume that shouldn't be there.
​Currently I've found 2 popped components:
Q5009 (AO4620; MOSFET N/P-CH 30V 5A/7A 8SOIC)
C5007 (unknown value capacitor)
I've removed both and still have a short. So 2 questions:
1. Is there a specific place I should start my search?
2. Would voltage injection work in this situation?
3. Bonus question: any shot someone has a schematic... -
Hi, I did look everywhere to know if Samsung Y Main boards LJ92-01732A without rev marking is compatible with LJ92-01732A rev AA2.
If they are not compatible why did Samsung give them the same part number to begin with?08-04-2025, 11:35 PM -
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...
