Hi all, hope you and your familly are fine.

I recently bought a ZALMAN HD160XT case with integrated LCD Touch Screen
Was thinking the LCD was working fine but after few seconds (from 60s after cold start, then 5s), the LCD loose power.
If I unplug the LCD power connector and plug it again, it receives power then, 5s later, it goes blank and the small green LED on the PCB does the same.

As I am a noob with electronic components, can you give me an Idea of components that I should test and how (I only have a basic multimeter) ?

Thanks for your help and have a nice day ! 😀

It might be worth a try to give plenty of contact cleaner to the connectors. Might just be oxidation. But be careful not to soak the lcd 😀

one of LEDs is shorted in the backlight, this trips the protection in the backlight DC to DC converter circuit. Is the LCD disassemble-able to rebuild the LED backlight LEDs or replaceable with generic LCD?

Question is, is backlight still on but LCD blank?
