Hello, i have a 50 in samsung pn50b550t2f. when i power it on it clicks to turn on, then clicks off. if i leave it plugged in it will continue to try to turn on then power off. I have unplugged my x sus and y sus and problem still remains. If i unplug the t-con board (aka logic board) it will power on but still no picture.
on my pcb i have all the proper voltage at the pins, stand by voltage ect. the only problem with voltages is the VA test point gets to 36 volts before the tv will power off, should be 58 volts. VS is 3 volts, ve 3 volts and vscan is 0, granted tv only powers up for a couple seconds.
no bulged caps, no burning smell, no signs of arcing. Im looking for guidance of where to go next. I was going to change out my PCB and/or logic board but i dont want to throw a bunch of money into this set. i read there is a small chance it could be the main board.
*A service manual would be ideal*
Thank you in advance everyone
