Symptoms:
1. Menus taking several seconds to react.
2. Occasional total lockup requiring hard power-off to escape.
My Humax HDR is nearly 8 years old and the above symptoms have started quite recently. I have checked the remote batteries and they are OK; the 'red light' on the remote operates when buttons are pressed. Lockups have occurred when the HDR is recording 2 channels and I am deleting a watched programme. Last night my wife managed to get a lockup by going into the Red Button service while 2 recordings were taking place. Fortunately, although the box is locked up, the recordings continue until the power is removed. Left to its own devices the HDR would record until the disk was full. BTW, the HDD is only 16% full.
So, might it be a failing HDD or a failing PSU?
