Re: Samsung UN40ES6100 backlight periodic flashing

You need to troubleshoot the unit causing the backlight intermittent behavior by forcing the power supply board voltages out connecting 1k ohm resistor between standby and ps on to observe if the backlight voltage is steady or fluctuating this must be done without main or logic board connected.If confirmed ok then u need to test the backlight for defective LED.This forum don't respond to assistance arcane incantations.��

Re: LG 47LX6500 backlight off after a sec. no video

Seems this patient have shorted Led ,have tried removing the LED connection from the main board and observe if the sound occurs?open circuit or connections from the power board can also cause such intermittent behaviour.

Re: Samsung UA32EH4000 (Bn41-01777) mainboard dead

Have you carried out voltage test on the switching Mosfet regulators on the board?Some of theses regulator can render main board ineffective.Also knowing the current symptom of the tv will as well help to solving the main board issue.Biafran.
