Re: Help with Samsung S42AX-YD01 Y Sustain and Buffers



So i pulled the PSU out of the Panel and bench tested it with the jumpers on.. it powered on and stayed on with not blinking alarm led.. so this bring me to the conclusion that there must be a faulty Y, X, E ,F board somewhere in the mix..


just on another note.. do you think that my "new" Y Sustain that i put in the S42AX-YD01 would be ok to run with two New Buffers?...

Re: Help with Samsung S42AX-YD01 Y Sustain and Buffers

Oh sorry.. i may not have explained myself properly.. the Blink codes are on the ALARM LED on the PSUs, according to the manual i have hey relate to D5VL OVP, UVP .. the brands are PHILIPs and the other is unknown..

both have Samsung PDP's and internals

the models are: S42AX-TD01 and S42SD-YD07

and both have the Samsung Version 4 PSU ..

basically LED8002 and 8001 come on briefly.. followed by a coupe relay clicks and then go off and i get the ALARM 13 Blink code repeatdly...

The PSU's that have the 13 blink error code(s) are PHILIPs and the other is unknown..

both have Samsung PDP's and internals

the models are: S42AX-TD01 and S42SD-YD07


the other Plasma that i would like to get working again is the Sampo 50" model: PDP50WXDP1#



i read another one of your posts a while back about the samsung blink codes on the PSu and yeah.. you said they were firmware related and if they hadnt updates the firmware...

Thanks PlainBill .. was hoping you would chime in..

.. so i had abit of luck over the last few days.. i scored 8 plasma screens 42-50" for $20.. all broken.. but good for parts..

after pulling them apart i got another S42AX-YD01.. this one had a different power supply though.. pulled the Y sustain out and it looks prity good.. no heat damage.. pulled the Bufferes out.. the Lower was definitely dead .. the upper still had a couple hundred K Ohm.. so i put the "new"...

Re: Help with Samsung S42AX-YD01 Y Sustain and Buffers



Yea from what i read and see they seem good, i have email'd Copells.. the problem i have is that i live outside the US and shipping in and out is a killer.. if my Ysus is damaged i will happily send it over with my buffers for refurbishment.. im just trying to work out if theres a good chance its not dead.. in order to save on postage.. and ultimately.. the fix bill :-)...

Oh.. My apologies.. will do...

Hi Guys,


This Set was exhibiting signs of an about to fail Lower Y Buffer before it stopped working completely.. (the lower half of the picture would die and then come back on after a little while) i have striped the set down and have diagnosed down to a bad Y Sustain board and/or both failed Buffer boards now.


i have used the information in the blog at coppelltvrepair.com to check for a short between the two groups of legs.. and i get a reading of 15K Ohm..
