My HD HG400LAN started to refuse to wake up as programmed. It goes to sleep at 11 PM and the light flashes. After the time when it's supposed to wake up (8:00 AM) the light turns off and I have to start it manually. I tried setting up the wake up time 15 minutes after the sleep time and it was able to wake up. But when I set the wake up time back to 8:00 AM continues to refuse to wake up. It's the hardware dying? It's any capacitor at fault? Any Ideas to fix it will be welcome. TIA.
