Octagon SF8008 continuously switching to standby every other second on all images.

Had the SF8008 for more years than I care to remember and it's suddenly decided to continuously switch to standby and then switch back on every other second. After I do a cold reboot it works normally for approx 5 mins then starts to switch on and off. This occurs whatever image I boot to in the various slots so looking like a hardware issue. But interestingly this doesn't occur when booted to recovery menu. Likely a capacitor or such like gone on the PCB I imagine. Any ideas? Or is it time for a replacement?

Yes likely the problem. Intermittent fluctuation in potential (voltage) to the receiver causing the persistent on/off issue. Will give it a go thanks. :)

I see 2 different power supplies, one is 12v 2amp the other is 12v 3amp. Which have you got ? It may be worth trying even a 4amp supply.

I used an old laptop 12 volt supply that fitted. So plenty of current from that. Also wouldn't be anywhere near drawing that amount of current anyway,but thank you for the suggestion. Didn't want to sound ungrateful

Immediately after starting the box, disconnect the front panel from the box's motherboard and observe whether it continues to turn on and off.

I had something similar - the menu would start automatically every now and then. After replacing the front panel with a new one, my problem stopped.

Of course, the test was previously performed with the front panel disconnected.

You were absolutely correct. Issue was front panel. New front panel display now arrived from Germany and fitted and now all working fine again. Thank you for your help azman26
