TerraMaster Forum

So I have had my f4-423 for about 3 years. Followed installation instructions, was working great. I had a little snafu with upgrading to sick but the team helped me through it. Everything was up and running and I had it back to I like it. 2 days ago I came home and it was off. I tried to restart it and it nothing. It lights up for about 10 seconds and then it clicks off. I took all the drives out. Tried again. Nothing. Took all the nvme's out. Nothing. So no harddrives, just the plug, and the lan hoping that that will light up. I have tried the reset switch, holding it from 3 seconds to 30 seconds. No flashing lights. I reseated all the ram. It is the original power plug. I run it through an APC power supply that that consistent current and backup. I have made no other changes.

When I turn it on, the light goes on for about 10 seconds and clicks, goes out, then starts again, on 10 seconds, clicks, off 2 seconds and the cycle continues. I have left it on overnight like that thinking something may change, it doesnt. No difference when I put the nvme back in after following the instructions on formatting and partitioning, nothing. The only times a light comes on is if I put the raid array back in just showing that they are there no light on the lan. Can't connect through TNAS. No connection.

Any other suggestions would be helpful but I think it's dead and I have no idea why... No bios or updates either. Like I said, I got it up to 6 and it had everything running like it should and then boom, it was dead.

thanks,
tokin

Do you have a monitor with an HDMI connection? Try attaching it to the unit. Might display something. No beep codes when you power it up?

No beep codes, nothing comes up on the hdmi. There isn't even an initial beep. It's just the light comes on for 10 seconds and it is like the click of a bulb turning off, not a beep. And it will just cycle like that for as long as I let it. If i hold down power to turn it off, nothing happens, cycle just continues. Single light, fan will give a little burst, than that is it. I have to unplug it for it to stop.

From your description, it seems to be a motherboard issue. You can refer to this post for final confirmation:

Can I just replace the battery or do I need to use the cord?
Can it have anything to do with the initboot being corrupted, or is the first beep just the hardware bios check?

You can replace the battery, or you can use a wire to short the '+' and '-' terminals of the battery compartment. The first beep usually indicates that the RAM self-test has passed and the BIOS has been initiated.

Okay, when you say use a wire to short it:
It is taken apart and unpowered.
I take out the battery. Connect to the+ - terminals.
Am I plugging it in and starting it? Is it on first?

I needmore instructions please!

I found more detailed instructions. Same thing. Same dull click and then it attempts to power up again, then 10 seconds does it again. Tried new battery. Took out ram and replaced with original 4gb terramaster dimm that was never opened.

It's dead. What do I do now? What are my options?
