Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM811, CM812, CM817 & CS806; 1000ufd 25volts.

Good Luck, big IRISH.

I would check out the power supply module for bad caps with bulging tops. Check DC voltages at the output connectors, you should have 5, 12, 24V.

It might be your anti-theft alarm system. When the car doesn't start, is there a ticking sound inside the car? If so, hit the unlock button a few times on your keyless entry remote, until the ticking stops, then try to start the car. Hopefully this helps.

Samsung clicking on and off but not coming on


The bang you heard was probably a capacitor. Since you are still hearing the TV attempt to power on, your power supply and it's fuse are likely fine, but if the capacitor was on the mainboard, the TV would require service unfortunatley.
