Yes it may be power supply issue. There is a IC Chip that controls the power. It is not something you can fix yourself. Take it to a service center.

Its a general fault however all these units are under a 3 year warrantee the dates printed on the back, just call 08706010309 speak to a service engineer and they will arrange a swap out within 5 working days, no need to a receipt as they can tell the units age from the serial. the replacement will be under the same 3 years cover in my case it was for another 6 months

TV always has high voltage shock risk while repair. As you said you are not familiar with TV repair so better to handle repair person this issue.

SOURCE: Samsung 55" TV does not turn on

CHECK YOUR RED ,GREEN AND BLUE CRT'S THERE MAY BE A SMALL CRACK ON THEM.MAKE SURE TO TAKE THE YOKE OFF AND INSPECT THE ENTIRE TUBE IF THER IS A CRACK IT IS CAUSING YOUR TV TO GO INTO SAFE MODE. ALSO CHECK THAT NONE OF THE COOLING FLUID HAS DRAINED OUT OF THE TUBES ON TO THE CRT BOARDS IF SO REPLACE THE BOARDS AND CRT IF CRACKED. YOU CAN FIND ALL THE PARTS AT PARTSTORE.COM HOPE THIS HELPS.

SOURCE: Power turns off right away

Its correct, Sony is no more selling plasma and I think many companies has already shut plasma production and CRT TV as well.
All TV manufacturers are busy in LCD TVs.

2021 Samsung 55 4K QLED SMART TV IS TURNING ON AND OFF

The most common reasons for the TV to turn on by itself is having foreign matter around the power button of the remote control, external devices connected to the TV, and your settings. If the power button is stuck, clean the remote control.

How do I fix my Samsung 40 LED TV that has sound but no picture?

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

BTW, here are solutions for you to play iTunes movies on Samsung smart TV

try the power supply capacitors. They would be the ones that have bulging tops.

Having power issues

Look at the power supply board for capacitors that have gotten "puffy" on the top. That indicates a failed part. Shopjimmy.com has repair kids.

Samsung 55" turns ON/OFF by itself and will not connect to wifi network

I have the same issue. I read and watched online tutorials about the compositors but after opening the set up I was unable to find any that had gone bad. I was able to upgrade the software by using a USB thumb drive but the issues are still there. I'm thinking of swapping out the motherboard and/or the power board next to see what the fix is.

Samsung 55 inch Smart TV

It sounds that a capacitor inside the circuit of the has failed. It might have bursted. Check the power supply regulator board for the trouble. Normally electrolytic capacitors at this section should be suspected.
