Re: Need some help with sammy plasma
I remember vaguely on the 50Q91 if the TV was on AV it would auto select the input source.
What I don't remember is whether it would do this when on TV or if the TV resumes in the same mode after being turned off.
The boards are different and I believe the 2 missing white connectors are to do with the side panel connector. On ours the "C91" which was the base model, had those missing and the front filter screen was not tinted like the "Q91" upspec version which had side HDMI input as well and additional connectors on the MB.
Samsung PS-50Q96HD- Main AV - BN94-01177D - BN41-00813E-MP1.0 - BORDEAUX PLUS
Samsung PS-50C96HD - Main AV - BN41-00879B - BN94-01223C - MTK_DTV_MP1.0
Edit: the Q has Anynet+, HDMI 3 side input panel, menu differences eg. movie plus in picture settings,Last edited by tw2005; 05-11-2013, 04:23 PM.Comment

Re: Need some help with sammy plasma
Thanks for all your help guys im sending the boards back so im going to have a go at fixing the y-main myself and purchase a buffer board sometime.
Ive seen repair kits for the y-main on ebay will these have the majority of the main parts that usually fail? Ive tested vs to ground and it is shorted. All the caps look ok so maybe its a couple of fets whats the best way to go about narrowing it down.Comment

Re: Need some help with sammy plasma
Could be power board - check common dry joints. Can also be shorted X/Y main so make sure to isolate those.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.Comment

Re: Need some help with sammy plasma
The power board was tested in another tv and is 100% working.
I tried to start the tv without the x,y,buffer boards connected but still clicking .
I have only the control board and the main board connected to the power board and green light comes on for a sec and shuts down .No ribbons connected to any of the boards.Comment

Greetings all!
Originally this set had the usual messed up video symptoms such as: horizontal lines, weak, grainy video, bottom and top of picture differ in intensity of problem. It also seemed to slow to turn on or show the messed up picture.
Seemed like must be YScan/buffer board failure. Ordered buffer boards from my distributor which were supposed to be original/new and also from another distributor, I ordered the YSUS because I wanted to replace it for preventative maintenance. (also, the YSUS had a bulged cap, so there was even more reason to suspect it could... -
Hi all,
I am trying to fix my plasma TV which is not powering on due to damaged IGBTs. I have changed two igbts and 2 IC drivers on the zsus and also two igbts on the ysus.
Now everytime I plugged the ZSUS and the YSUS boards to the power board, the two 30f124 IGBT on the ZSUS are damaged and the TV stays in standby mode. When I plug the ZSUS board alone the TV turns ON but I do not see pictures. When I plug the ZSUS board without the two 30f124 IGBTs and the YSUS board, the TV powers on with a picture.
I am lost, should I change the YSUS board? Is the YSUS board damaging... -
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...
