I had the same problem… after doubting that another power supply would work, it did… somehow

I have the same problem. How did you fix this?

Changed the HDMI cable, still no signal. Changed the power supply, works perfectly!

Hi I have MXQ 4K 5G There is power on but no signal And the processor is heating too much

I have the same problem, do you have a solution?

That was the problem for me too. You need to get a better quality HDMI cable first, it didn't work at all with the original. After pressing the restart button, I just unplugged the hdmi cable and plugged it back in, it was okay. I used to do it with the power cord, but it didn’t help.

Wow nice but i try this but always fade😥😥😥i think ill buy another hdmi

did not support different resolution hdmi cable with all device ...

How to fix no signal hdmi mxq box to t.v ? Pls help me

You just switched the box 🙄

dude , I had the same problem after having attempted to flash the firmware since the manufacturers was updating the aondroid/firmware version. It resulted in exactly the same beahviour. It seems to feel like its by design with a duff flash firmware being offered on the internet. If anyone knows a fix or knows how to get around this problem please drop me a line....Excercise CAUTIION when getting these dodgy flash images online.......

What was the point of the qtip...

I got same problem... Please advise how to fix it

i had the same problem i tried to replace hdmi cable it did not work i tried it on another tv it did not work . the problem is you think your box is working perfectly bcz the blue light in the front but its not , the real problem was in my case in the power adapter it is written on the power adapter 5 volt 2 amp but the problem it gives you 5 volts but not 2 amps so som functions on your box works bcz they dont need 2 amps like the blue light in the front but others wont . so i tried a power adapter with 1 amp it showed the logo at the beginning then it disconnects so i tried one with 2 amps so it works perfectly.
