I am using Raspberry Pi 2 with Raspbian OS.
It is connected with usb wifi adapter, a bluetooth adapter for keyboard and power supply is 5v 2000mA AC/DC adapter.
RPi goes blank periodically for a second and comes backs to normal on LG TV 32LD340.
It is strange but when I plug my fan on 5v pin. It stops blanking. But sound output stops. After unplugging it makes display blanking again.
I tried bootconfig, even set HDMI group and mode to 1. But it also goes blank in that case. Currently
hdmi_mode=39 1360x768 60 Hz
On Samsung it works well
How can I solve it?
Switching to more stable adapter with 5.v 1A solved the problem. I am still testing. Now I am using
