Re: PDS 4250 sky plasma
Wouldn't bother. Got a 42V5 panel so only 853x480 pixels, not even standard definition!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: PDS 4250 sky plasma
Hi Tom/anyone.
I've got one of these PDS 4250 plasma screens and would like to fix it if possible. It powers up OK, but doesn't pass through any video input signals, instead showing a sort of fine zig-zag coloured pattern. If I connect my PC to the PC input, that does work (though not very good). That, and the DVI input show, 'no signal' when selected without anything connected, but the others all show the strange pattern instead (with or without input) - it just fails to pass through any of the SCART or Component inputs. Any ideas? I'm an ex-TV engineer (25+ years ago!), but have no experience or knowledge of plasmas and no circuit diagram, so am at a bit of a loss as to where to start -I can upload an image later if needed. Maybe a low voltage supply missing? Any help would be much appreciated. thanks.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... -
