ips 7'' display blinking

Post by nesteant »

Hi,
I have baught next item:

HDMI 4 Pi: 7" Display 1280x800 IPS - HDMI/VGA/NTSC/PAL PID: 1931

The problem is that monitor started blinking with backlight when it is not connected to the board. When it is connected - the image is not bright and the backlight is still blinking.

When I powered the board first time - it was working fine but the temperature of the panel was around 45 degrees. It worked for 2 minutes and I have powered it off. The next day I have assembled the power supply from the atx adapter and after turning it on I have seen this blinking feature. Currenlty it is blinking with any 12v power supply. IPS matrix is not heating anymore (temperature is less then 36 degrees)

Could you post clear pictures of your board and the connections to it?
