I'm sure you have it figured out by now, but, there is a power switch on the right hand side, underneath the television, about a foot from the end. Make sure that it is depressed.

I could be one of your fuses, the only problem is you have to take it appart and if you don't know how is better to take it back where you bought it.

I have a 50" haier tv that won't come on tried numerous plugs in my house moved it from one room to another and it quit working


Sounds like it died a noble death. U might want to check out the Power supply first. Also check the cord to make sure that power is reaching the unit.

Why wont my lg 50 plasma tv turn


Perhaps replace your power cord. Borrow power cord from repair shop. If it works it's the cord. Also if the TV is plugged into power bar make sure the power bar hasn't been inadvertently turned off.

Came home and my TV isn't workin . I bought a new power cord but that didn't fix it . is there a reset button on these TVs????


Are you sure that the outlet is providing power to the set? If so, then the problem is most likely with the power supply of the set if it is dead.

Help new power supply will not power up.


if you had a surge, it could have damaged more than just the power supply. When you plug in the unit, does the power indicator light up??? your main board could also have damage. The main board sends a signal to wake up the power supply thus turning on the TV. If you have to replace the main board as well, it probably won' t be economical to repair the set.

I have a CLT2054 and lost the power cord. I bought a new power cord but when I plug it in the light on cord goes out and TV wont come on. If I un plug cord light comes back on


You have short circuits inside the TV, the AC goes into shutdown when it senses too much current being draw. Post some pictures inside the TV if you can, wee need to look for short circuits, another thing, you bought new AC adapter with the same voltage and current rating, right?

Tv sparks bad when i apply the cable cord to it


EXTREME DANGER!!!!!


PLEASE LISTEN CLOSELY:

all appliances made in the last forty years have a polarized power cord.

One pin on power plug is small and other larger--the larger goes to the neutral side of the electrical outlet.

If you get sparks when you hook up the coax to the cable fitting--only one of two possible reasons.

Either the polarized cord has been defeated (plug modified) or the outlet you are plugged into is not wired right.

Understand--it does not have to be at the set you are using---if somewhere else in you home a cord is defeated or an outlet is bad--it will feed the problem via the coax to every other set in the home connected to the same line.

What you are seeing if you get sparks is the coax fitting has 120 volts AC getting to it either by the coax or from the power outlet--

The easy way to find this is disconnect all coax connectors in the home and with a voltmeter hooked to a earth ground (like a ground rod or pipe made of metal) measure for AC voltage to the coax.

THIS IS A VERY DANGEROUS SITUATION-BE VERY CAREFUL--

If even one set or outlet is bad it will feed this via the coax to all sets in the home---I have seen this before-yes it can destroy a TV! but it can also hurt or kill someone--this is the reason all power cords are now polarized.

IF YOU HAVE ANY QUESTIONS ASK ME--IF IN DOUBT HAVE AN ELECTRICAL EXPERT CHECK THE WIRING AND MEASURE FOR AC VOLTAGE TO THE CABLE--ac voltage can kill--it is the same as connecting a wall outlet to the exposed areas of the set.

THIS IS SERIOUS STUFF--DO NOT TREAT IT LIGHTLY!
