Re: NIKOS MOSFET replacements
Hi Rich,
I have a similar issue - tracking down some P1504BDG and P2504EDG MOSFETs.
These are for a slave inverter board out of an LG 42LG3000 LCD TV.
Did you have any luck with the Sanyo ATP106 and ATP206 MOSFETs?
Thanks,
Stuart.

Re: Samsung PS50C550 briefly turns on with partial white screen
Hi Tom,
I have acquired a scope with a 10x probe, the scope is a bit antiquated but a scope nonetheless.
I will be home a bit later to do the test, can you provide a link or give me some details of what I need to test.
Thanks for your help by the way.
Regards,
Stuart

Re: Samsung PS50C550 briefly turns on with partial white screen
Hi Tom,
Thanks for the reply.
The TV behaves exactly the same with pins 3 and 4 shorted on the test connector shorted.
I have measured the Vs and Va voltages after turn on and these go up to the correct level but drop straight away, but these voltages stay steady at 211V and 55V with the Y-Main board ribbon cable disconnected.

Samsung PS50C550 briefly turns on with partial white screen
Hi,
I have a Samsung PS50C550 plasma that does not turn on.
The screen flashes on briefly for a split second, i have taken a video of this and managed to get the frame out that has what is shown on the screen when it powers on.
It looks like there is an issue with the left side of the screen.
Can someone help me diagnose this fault, my suspicions are that the screen is broken but if it is electronics and can be fixed that would be great.
Many thanks,
Stuart...

Samsung PS50C550 screen not powering
Hi, this is my first post.
I have a Samsung PS50C550 plasma with a smashed screen (don't ask), after the screen got smashed the TV would make a 1(ish) second buzz then turn off.
I found another Samsung PS50C550 on eBay that had a good screen but apparently had "just stopped turning on".
I have moved the good electronics over but the TV will not turn on, after this I started googling and looking for a service manual but to no avail.
These are my findings though:
With all the boards plugged in I get 6 flashes from...
