Hi i have a samsung LN40C540F2F i want to fix.when i put the power plug the red light flashes 6 times stops and remain like that.
i took the unit apart and measured the voltages ( see picture)
the powerboard seems to be good according to the voltages and no bulging caps.
the backlight is working fine if i unplug the connector between the PSU and the mainboard ( saw this trick online with this particular set)
i suspected the mainboard not sending the PS_ON voltage (0.9V), but i have read a post here in this forum a guy had 0.8V and the tv was working fine.
i'm leaning toward the mainboard, but i would like to have your input please
thanks in advance
