Ok i will try this. When you say power down completely do you mean by the main switch on the back? Or unplug entirely?
So the process is:
1. Power off then on in current standby mode (GREEN)
2. if no result then select next standby mode (power save) and power off then on, and if no result
3. Select final standby mode (normal) and power off then on and if no result
probable thermal protection fault?
Thanks for this help and advice!!
