Customer Question
I have a UN56F...

I have a UN56F 55" that clicks on for a second then off. It keeps clicking on and off and will not come on. I tried power cycling it and that did not work.

Technician's Assistant: Is your TV connected to a surge protector or power strip?

Yes.

Technician's Assistant: Have you tried to power reset your TV (unplugging the power for 1-2 minutes, then plugging it back in)?

Yes. I tried a couple of times. I left it off for a half hour the second time.

It makes a clicking sound and the screen comes on for a second then goes black. It keeps doing this until I unplug the TV.
Customer reply replied 7 months ago
There was no thunder or lightning.

OK, does the TV show Samsung logo/ any graphics when the screen comes On for a second OR it just glows and shut Off then repeats?

It shows "Smart TV" for a second.
TV Technician: Shahid, Technician replied 7 months ago

Thanks for the info, unfortunately, it is hardware related failure inside TV and most likely the mainboard problem that boots up, resets due to internal failure and reboot and again resets, this process goes on and you see it as TV repeatedly on-off.

Mainboard is one where all video/ HDMI inputs are located, replacement of mainboard will fix the issue. Please click the following link to view mainboard image and part number info (crosscheck the part number off of main board installed inside the TV) to search/ google it to get price info if you have the plan to work on it yourself.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make the decision about this TV repair or invest that money in new replacement TV.
If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page so I can get the credit for my work on the website.
