:'(I'm sorry, but neither the remote cleaning nor the new PSU (I've tested two new PSUs, one with 2 A and one with 3 A) have solved the problem. So, as I supposed, there should be another cause of the problem, but I don't know which one. If you can suggest something else, I thank you.
Sorry to bump this thread.
I am facing the same issue.
My front panel doesn't respond to anything, and I use it to Power ON the device by touching the red light. All the light are there but nothing responds
But now since the Front Panel is not working I can't turn it ON anymore, unless, I do a reset for firmware upgrade everytime.
So each time the unit gets OFF accidently, or hangs, then it will take me at least 20min to do the a firmware upgrade every time. Cos that's the only method to get the unit to ON.
Anyone facing the same issue?
My remote has died a long time ago so that's why I ON the unit by pressing the Red Light.
Please help. Thank you in advance.
