52144 turns on and off by itself - Televison & Video

The should from 4 to 6 screws near where the base & tv come together. They are either #2 phillips or torx(t-20 or t-25) screws. Unscrew and the base pulls out straight down.

Hello. I was in a live session with you earlier and it seems like you accidentally closed the window. Does the tv tv click on momentarily before it shuts off and starts blinking?

if not in warranty, and if you are a DIY i would open and look at power supply board, you may see a cap or 2 bulging open.

Sounds like tuner board depending on the lines

you need to buy the power suply go on line

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.
