Mecool KIII pro hdmi output failure
#1
Hi, I am a user of K3 pro device since one year. I am very glad to have a nice device. Last week when I saw a new firmware update, I tried to install this one. But it failed cos I tried this via usb stick. It gives me a E3004 error. Then I tried to flash via usb burning tool with pc. My mecool screen has gone. I connected box to Laptop via usb cable. I flashed this device four times. Every time it gave no screen via hdmi connection. Box give me signal via AV cable. I tried to change all hdmi port of my tv and also different tv port. Nothing changed and no hdmi signal. What can I do for this fault?? Please urgent help..

Flashing procedure ended perfectly. My box works with blue light and I am using it without problem via AV cable connection. But when it is connected thru hdmi port, no image is came thru hdmi port. This is exactly my problem. You can see this in pictures attached...

Hmm....
Did you test it with other HDMI cable?
Did you test it in other TV?
Did you change the resolution from the settings?
Did you try it after a factory reset?
Tell me what things have you done from these!
