Samsung Blink Codes

Getting a 1+5 code on a UN40H5203. Looks to be a first generation LED set. Around 2013 model.

Samsung doesn't use blink codes, nor do they store any codes in the service menu. There may be a factory interface that could make sense of that but Samsung never shared that with ASCs if it does.

Unplug the TV, disconnect the harness between the main board and the power supply. Plug the power cord in. The backlights should come on immediately.

If they do, the power supply and LEDs are good. If the LEDs stay dark, then it's either a bad power supply or an open LED in the display.

If the back lights come on, reconnect the harness and disconnect the harness at the wifi card. If the TV starts, the wifi card is locking up the main. If it's still dead, disconnect the ribbon between the main the TCON board and try again. Still dead? Bad main.

If the back lights did not come on, then you have to determine if the power supply is bad or an open LED exists. I use an LED tester which puts out up to 325 volts at 20ma to test the strings. If you don't have a tester, you can check for DC voltage on the power supply LED output to display connector from pin 1 to pin 9. If you get no voltage there, the power supply is bad. If you get a 125V or more, then you have an open LED inside the display.

On the H series, if the back lights don't come on with the main board unplugged, the odds are about 95% an open LED inside the display is causing this. A very small percentage of H series Samsungs have bad power supplies.

So, does the LEDS must come on before the rest of the set comes up, even to get sound?

Downloaded the training manual and apparently that is the case with the Smart TVs.
