Geeetech A10 - Powers on but lcd does not work

[TaylorTam]

Hi

I recently got the Geetech A10 and have had a good few sucessfull prints but today i took apart the hot end to unclog it and i think it blew something. The printer powers up and i can hear the fan in running but the lcd does not power on so i cant check if it will heat up or select anything.

Really not sure what the issue is i have seen some on this forum and people asking for a picture of the motherboard lights so i have attached an image of that

Hope somebody can help i really want to get back to printing

thanks in advance for any replies

Hey, So i have checked the voltage on the main board with a multimeter (I am a novice so not sure i've done it right) to get a consistent reading i have to set it to dcv 200 and it comes out as 24 which seems a bit off but that's what i get. Again not sure if i have done that right so bare with me

thanks Ryan

Hi，my friend, can you tell me where you are measuring the voltage on the motherboard?

Hey,

These are the two points i tried to measure from like i said i wasn't too sure where exactly i should be measuring from. I did test the multimeter on a battery to make sure that it worked and it did give me the right reading, so at least i know that the multimeter does work

thanks Ryan

Hi，your motherboard is broken, you can replace the motherboard.

Thanks for your help

I thought that might have been the case, I have noticed some frayed wires around the hot end so i think that might have blown it. SO i think i'm going to replace that too

Thanks again Ryan
