Samsung ua40es6200 TV no display

[AdrenalinTL]

Hi,

Got a Samsung TV that has no display. Did a bit of troubleshooting.

When I first got the TV, it worked, about 2 years ago. Left it in the garage, and now it has 5 blinks of the power light.

I unplugged the main board from the power board and the display blinks for less than a second constantly. Almost as if it's trying to power up but can't.

Anyway I tested the fuse and there was 0 displaying on the multi meter.

Now the 5 lights have suddenly vanished. No idea why.

Here are the boards (Bit of an odd model I think?)

I see no visible damage to anything.

Thanks

First, you need to indicate the TV model, motherboard and power supply numbers.
Secondly, where will you get five blinks of the standby LED if you disconnected the motherboard from the power supply?

It's a Samsung ua40es6200

Power supply is a BN44-00518C

The 5 blinks happened when I plugged power in initially. The standby light blinked 5 times. Other posts seem to suggest that is just a power on light and doesn't mean anything specific.

A bit of common sense would be to download the service manual for the TV! A quick google will show a free download for it here https://elektrotanya.com/samsung_un4.../download.html
Then start reading and checking for voltages on your power supply, ensuring that you are fully aware of the risks when working with mains voltages! If you are not then leave it to someone who does.

Thanks. I am still very new to all this and have been shocked before by DC voltages and in general just don't like electricity.
That being said, I am trying to learn electronics.

Can this be narrowed down to the power supply though or could it also be something else? I could replace the whole board if I find another one?

IM not a tv repair engineer but if you have a service manual as said you could test the voltages. This link satells you samsung error codes: https://9meters.com/technology/tv/sa...-and-solutions

What's that incomplete guide? OMG..

Ok cool thanks, will investigate a bit further. Not keen on testing voltages but have an electrician friend who can maybe do it and teach me at the same time

Need to start someplace, try testing the diodes and resistors on top of the board, can also check the soldering on underside of board, search for images of bad solder joints if needed. Youtube is your friend for how to videos, also some troubleshooting voltages here. Heed the HIGH VOLTAGE warnings the /primary/hot side can be deadly: https://www.youtube.com/watch?v=fbcCVv_ahBo

Thank you. Nice video.
