Do you have a green LED or any other lights on?

The power switches in these units can fail.
you can by pass the power switch to check.

If you have a multi meter or volt meter test that there is voltage on the circuit board.

Another likely fault place could be the power connection to the circuit board.

If you have a small battery AM radio, hold that close to the UHD with the power on, it should get noisy if the computer is running.

The satellite menu is Menu / right arrow to installation and OK.
This for standard GT Media software, not m4rs.

Thanks for your reply
I have checked on the multimeter but I am getting a 12 watt power but the power isn't flowing into the circuit board

So 12V is at the circuit board where it arrives from the switch?

Plug something into the USB that you can see is getting USB power.
that will show that the 5V supply is working.
You could also test that 5V is there with the volt meter.

Thank you for your reply
Yes 12V is coming from the switch but not going through into the circuit board
On the whole of the circuit board there is no power supply

Check the soldering of that 12v connector.
Also th power cable wire connection.

You can bypass the switch on the JST connection with aluminum foil

I don't see any obvious fuse.
The power comes in the 5.5mm plug and then goes to the switch and back.
With your volt meter check that the power is on the board at each point, the 5.5mm connection and then the return side of the switch.
Check the switch return side on the board, not just the wire in the plug.

Check at this wire as power returns from the switch.

Check on the under side of the board at the same spot.

I will open my other UHD tomorrow and look for you, the model I had today was very early proto type unit they sent me.

In that area marked with a white line you can check for voltages , maybe t the test points over by the HDMI connector.
I will get voltage value tomorow from mine.

Night here now, so last post for me for 10 hours.

Looks like you have missing components on your circuit board.

Also one looks like it got hot, a diode I think.

Were there loose bits rattling around in your unit before you opened it?

I can see one large component, likely a diode, and two three leg components that could be many things, FET, regulator, or transistor.

WHY?

Why are these not there?
is this a different hardware version?
Did a major fault fry these off the board?

If you have a hardware version, adding those parts may be wrong.

Questions I can not answer.

Maybe these were not added to the board in error at manufacture and your UHD work for a while with out them until the diode melted off the board.
