Hello. I don’t know if you will see my comment or not but I will try. So I disassembled my projector because I wanted to clean it from dust. I removed almost everything, then when I returned everything to its place and I turned it on the colors are gone and the screen became like an X-ray screen, all thing work but only this problem. So Can I fix it at home?

[@QuickFixRepairCenter]

Yes! you can. Between led and screen there is on poloriser which you place wrong. Just make it opposite the current position, your problem will resolve.🙂

Hello, I have a QKK2 projector that can connect to power but will not turn on. When unplug it in, light flashes green then to red. I tried connecting it to my computer but the projector will now turn on. I’ve tried turning in the power button but nothing is working. Can you help?

[@QuickFixRepairCenter]

Maybe the projector lamp is gone that's why lights flash green and then red

[@dhanushkarthik1176]

Hii bro, I need that power board, where we can ge it, kindly let me know please

Hello I'm from Brazil. mine is in trouble. I turn it on and it keeps going to home alone or moving the keys alone, I've already tried to unplug the manual control cable but the table remains , I would like to know if you know any solution for this

[@QuickFixRepairCenter]

It's difficult to tell solution like this without diagnosing 😅. I think you have to check pull up or pull down values of this button which is continuously pressing.

[@inah211]

Hi I have the same problem with my projector, were you able to fix yours?

i have same projector... when i turn on the projector red light ons, when i start projector screen blinks and turns off.......and returns to the same red light and if i again turn on the projector screen blinks and goes off

Might be not delivering enough power which is required. Hence it's getting off frequently.
