Re: Samsung LN40E550F7F backlight issue

I face similar issues with a Samsung lns3241d. It powers on, the back light flashes then goes off. I have image for a split second. I tested the plug to find I have max 4.8 v going to the inverter board and zero's out.
suggestions? caps are new

Re: VIZIO - P50HDTV10A dont turn on PSB has power

PS
fuses all test good
VS ect, voltage raises and lowers upon clicking power button
all heat sinks are cool

Ok I searched the forum and did not get any where. i am a nocice but a quick learner learning to do component repair.
When the tv is plugged in the relay clicks.
hit power button the front light turns green. then it flashes 10 orange blinks.
the PSB pis all read proper voltage so i have narrowed that out.
The 2 voltages to the y-sus are within in tolerance of the sticker.
I unplug all cables excpt the standby and it makes no diffrence, which makes me think it may be the PSB.

Any directions to go from here?

thanks for the group.
