SOURCE: power light blinks, but tv won't come on

I have the 52" version of the Viera model. Mine went out last night and started blinking twice over and over again. I suspected overheating so i just went to bed and tried it in the morning with no luck. Then I unplugged it for more than ten minutes and plugged it back in and everything worked fine. I hope this helps.

Another set where the LED's in the panel are shorted and dropping the rail down for them, you will need to take the panel apart and replace the bad lamps or strips but this isn't an easy job to do its very easy to damage the panel after fixing the lamps and have to throw the set out after all that work

LG 65UH5500 TV just died while watching it. Screen gone black, no sound.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My LG 50" smart tv turns off right after I turn it on. The LG logo comes up then disappears then the red power light blinks twice and shuts off. The red power light then returns.


the number of blinks by model tells you information. Look up capacitor failures on that model on youtube. I have a vizio that did the same thing, and it was a $0.11 capacitor I had to replace... took about 30 minutes, and working great. You'll need to see if you can find someone with that same problem on youtube to be able to find it easilly... requires soldering iron... little screwdrivers and some patience. you can do it!
