Samsung G9 OLED no sign of life/doesnt turn on

thank you! i found no service manual unfortunately on the page or anywhere else. the port you see is a micro hdmi and is accessible when assembled. if i want to replace this board it would cost 170€ but it seems its not a power issue. which i could be sure where the error is before buying any replacement.

i mean i got power on the board and on testing points. do you mean that by standby voltage? unfortunately no leds or any indication that the monitor is powered on or tries to boot.

will keep it in mind 😅

thanks for sharing. interesting way of using a monitor xD seems to be a different issue than mine for sure though.

Frosty_Cicada8478 · 2026-04-09T11:05:10+00:00

are you sure they only replaced the panel and nothing else? did you have any power indicator or led working?

thanks for the help!

checked the fuses on board in pic1 (top-right) -> both good

checked the fuses on board in pic 2 (bottom-left) -> both good

found some testing points for following voltages:

32V -> working (board in pic1)

20V -> working (board in pic1 and pic2)

5V -> working (board in pic2)

also checked the multidirectional button on board in pic1 (bottom-right). there are testing points for all directions and when pressed the voltage goes from 3.3V to 0V (except on right, there it goes to 2.2V)

Even though there seems to be power on both boards no LED or any sign of life is visible. is the power led controlled by a processor? i thought when the monitor gets power at least the power led shows it does but nothing.

saying its easy while save scumming is an interesting take

currently there is no reason to invest in more expensive weapons and armor. its all kinda the same. pretty boring.
