Have been using my Pi for 2 weeks, but recently discovered the monitor displaying "No Signal", and the screen went blank for a few sec before returning to normal display. I don't believe this is the config issue that other people have been up against. Powering down the Pi and letting it restart solved the problem for up to 30 min. but after leaving it down for the weekend, the problem is back this morning with a vengeance. Can't edit code! Once upon a time I thought the problem was triggered by performing an action which resulted in the display being updated.
I'm using an HDMI/VGA converter with a Benq monitor. Have tried changing monitor, VGA lead, and converter none of which has helped. BTW my Pi is an older model, the board printing says (c) 2011.12 ...
Is the Pi HDMI o/p known to be intolerant of HDMI/VGA converters over a period of time? Apart from the config issues, has anyone else seen (and solved) a problem like this?
hdmi_force_hotplug=1 is already in /boot/config.txt hdmi_safe=1 was hidden with a # at the start of the line
on rebooting, got the pretty rainbow colours on the screen, then nothing ... just blank :(
