During work, my E2311H got black and I’ve no chance to power on again.
Is there any spare part to check or anything else I can do myself to get it back to work.
Greetings

If there is still no backlight voltage, check the PSU diodes with the diode function of a DVM. If all of them check OK, check the transistors the same way = they are just two diodes b to e and b to c. I'm betting on diodes.

Hi @lassegismo
What I can suggest if it is not under warranty, to open out and check on the power supply voltages.
normally i can think of, either power supply board faulty or mainboard faulty which causes this.
do you have a multimeter with you?

@augustine yes i check the power supply and there is 18.5 autput for both boards but the backlight plug have no power i found 2 blown 25v 220 capacitors and change it but still not working
