If the red light is blinking on and off, it's likely that your TV has a bad power supply. If the red light appears but is blinking, continue.If that doesn't work, jump to the next section. If a solid red light appears, try turning on the TV.If that outlet isn't providing power, find one that is (you can use your test lamp to check) and plug the TV in there.

Plug another device (like a lamp) into the outlet the TV was plugged into.

If your TV has no light at all, you'll want to first make sure that the outlet it's plugged into is providing power. This is important because a loose connection here can cause power problems. Start by unplugging the cord from the rear of your TV and re-insert it making sure it is well seated.

We will start with electrical supply as well but with a different initial focus.

The blinking standby light means a power problem, it is likely the power supply board but there are a significant number of other potential causes.

We will start with the electrical supply.

No standby light could mean the unit is on with no display, or that the power to the unit is disconnected.

If that doesn't work, skip over the Electrical Supply section-your TV is receiving power. We can start by resetting the TV or resetting the remote.

A solid standby light means the unit is getting power, so we don't have to check the cord or the plugs right away.

If you see it blinking it indicates a problem, generally with power supply issues.ĭepending on the standby light, we will check different things first. You usually see it on when the TV is off (really standby) and you don't see it when the TV is on, or is unplugged (really off). This is the red light that is on the lower edge of your TV and it is the place where you are supposed to aim your remote when you are watching the TV. The first thing to check is the Standby Light.
