Hello,
I have a Samsung DM32D display.
When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.
Here’s what I have tried so far:- Disconnected the cable between the mainboard and the power supply → the backlight turns on.
- Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
- Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.
From these tests, I suspect the problem might be on the mainboard. Could anyone...08-24-2025, 03:47 AM -

I have the DA0ZPVMBAD0 rev d logic board and it doesn't boot up. I see all the voltages are okay. So I suspect the issue is bios.
When I power on with fn+ esc the blue light start blinking on mainboard.
I guess its a good sign. As all the voltages are okay and also charging indicates orange light when battery connected, I think it confirm that the EC bios is okay. So I ignored the ec and flashed main bios with 32mb bin file provided in the link below. But the condition is same.

Hi,
I have 3 of these TVs for repair with same problem of going to standby after around 10minutes and start again continuously. I have tried a new SPI 25Q40 but fault remains. Am suspecting a CPU problem as it gets a bit hotter than I expect.
This seems to be a common problem in these models. I am 100% sure it is a mainboard issue as I have fitted a spare from a normal TV from a UE40K5607 and stays on (diplay inverted but I managed to rotate in SM using a different display).
Any help appreciated!... -
Hi all,
I got a controller where the left stick was moving left all the time (-1.00 at calibration tool). Even after changing to hall effect sticks it stayed the same and reset and all others things didn't help.
I removed the stick again and even without it calibration tool shows a movement to the left. Anybody knows where the fault can come from? Maybe any bridges or damaged SMD components?
