Why is my Samsung TV not turning on? Standby light is on

Customer Question

Samsung TV will not turn on though the standby light is on. Neither the remote or power button on the tv will make it turn on.

What can I do to power up the TV?

How long have you had the set for and when did the problem occur?

Was it after a storm or power outage in your area?

Is the standby light lit steadily, or blinking?

Also, are there any clicking sounds coming from the set?

Customer: replied 5 years ago.

I've had the set 1-2 years. This started yesterday morning, it wouldn't turn on. Got home from work in the afternoon and it turned on. Today it won't.

There has been no storm or power outage. Standby light lit steady and no clicking sounds.

Expert:  Aric replied 5 years ago.

Please disconnect the set from AC power for 2 minutes, then upon plugging back in, press and hold the power button for 8 seconds to try and force a reset.

If the TV still does not power up, then there is a short inside the set stopping it from fully powering up.

Most probably there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail.

They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets.

The capacitors are located on the power board inside the set, where the AC cord plugs into and can be replaced by a technician for no more than $200 (parts and labor). There is no sequence of buttons or reset you can perform to get the set working again.

Do you have any experience testing live voltages, or soldering on electronic equipment? If not, then I would suggest using the link below to locate a technician in your area:

Had the 2 bad capacitors replaced. TV now just powers up then goes dark. Any ideas or scrap tv
Expert:  Aric replied 5 years ago.
You would need to perform more testing in order to determine which board has the failure. If you do not have experience testing live voltages, then you could be looking at upwards of $200 at a minumum to repair the set.

Turning into money pit. So now it could be either board or both
Expert:  Aric replied 5 years ago.
Correct. To determine which board is causing the problem now, would require voltage testing of the power supply both under load and no load conditions.
