Re: Samsung PS50C550 (S50FH-YB06) Sound but no picture (or glow)
yeah it said blink every .5 seconds is normal, every 8 is abnormal, 5 seconds on 2 off is DRV_RESET
think i linked it on the first page
guess i'll just keep searching around and see if someone else has come across itLeave a comment:

Re: Samsung PS50C550 (S50FH-YB06) Sound but no picture (or glow)
I'mnot exactly sure what it means
The logic board (if tthat's what it's even called ) has a green led that is on for five seconds, off for two
According to tgohome. Info?. Com? On a similar model, that means drv reset and it doesn't say anything else, other led patterns are normal or abnormal
Someone else said drv reset means the logic board is detecting something wrong in the high voltage side of the psu and shutting everything off or resetting something.. I'm not too sure...Leave a comment:

So since i have 10 and .15 ish volts instead, it's more than likely the psu?Leave a comment:

Re: Samsung PS50C550 (S50FH-YB06) Sound but no picture (or glow)
Ah, good.
with both sustain boards unplugged from psu there's no voltage at either Va or Vs
plug both boards back in and voltage goes back to where it was beforeLeave a comment:

Will do,
Also not sure if i mentioned this before but reading one of the other threads on this board you asked about relay clicks, there's relays on the psu that click when the tv is turned on and off
not sure if they're meant to click or notLeave a comment:

everything except Va is the same, Va was at .20volts, don't think this means much since its meant to be 55volts....Leave a comment:

Va 0.14 volts, doesn't drop
VSON shorted to ground
