Hi John, apologies for late response. I had a good look at your unit & as luck would have it, it was misbehaving straight away, which gave me a chance to see what was going on. The main processor was randomly & incorrectly detecting a streaming card (Bridgeco) hardware change & requesting a reboot. The data lines between the two are direct (no series components), the ribbons & streaming card had already been replaced on a previous repair. This lead me to believe that the main processor was at fault, which would also explain the loss of settings.
The processor is of course obsolete, which in turn, has lead to the main PCB also becoming obsolete.
At that point it was looking bleak for your Qute & I was unaware that the news had filtered through to you.
However, not one to be defeated, I persevered & managed to locate a main PCB, once serviced & fitted, the fault did not reoccur. So I’m hopeful it is fixed!
It should be back with you soon.
I will keep my fingers crossed!!
