Samsung 42' flat panel tv wont turn on

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Long shot, try turning off, unplugging, then hold the power button down for about 5-10 seconds. It will discharge the capacitors, which could be malfunctioning.

Try restting it by unplugging the tv for a few mins and it should rest to original factory default settings but leave it unplugged 10-15 mins to be sure.

Replace the power supply, PN: BN44-00206A

It's easy to locate, but requires adjustments once it is installed. Panel voltages must be adjusted according the the specifications of the TV. There is a sticker on the back of the plasma panel which provides each voltage setting. You can reference this sticker to make the proper adjustment. Using a DMM, connected between chassis ground and the panel voltage you are adjusting, turn the adjustments on the power supply very slowly, until you are measuring the specified voltage within 0.5v. I hope this helps and good luck.

Yes,make a noise to power up and turn off power only.But not in 30mins,with 5 or 6 mins
