Hello, actually the problem was with the HDMI cable. During safe mode it seems no signal is routed through the HDMI cable. So I replaced it with the original VGA cable &  display started(in safe mode). Thereafter from Run-MSCONFIG route I switched back to Normal mode.

Thanks all

"During safe mode it seems no signal is routed through the HDMI cable."

curious, I would have to do a test, but it seems that it worked for me
