you will need to check weather the 24vdc supply for the inverter board is good no drop voltage. if no supply check the power supply board. then you should check if their is a inv_on signal at the power inverter board around 3v-4.4vdc . if goes out during power on tried to disconnect the supply going to the inverter board to ensure if their is a shorted parts in the inverter board. if the inverter_on signal also goes out even with out inverter board connected that was mean you have problem in the processor board.

You can either GOOGLE THE MODEL NUMBER WITH SERVICE MANUAL or contact Samsung to see if available.

The cost to repair this problem is about $400-500 depending on local labor rates.With new flat screens as low as $500.00 it doesn't make sense money wise to repair it, this is especially true if the TV is more than 4 years old, flat screens last about 6 years at most before problem s start like burnt out back light bulbs (another $400.00).

bro you should take it to the repairer,No other options you have. it can't be fixed by doing anything accept changing it's screen or repairing it, if it's possible

Hello. You can check HDMI cable in this case. If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen. If you switch the cable or change devices and the TV is at a regular brightness, this is the case.
