The supply needs to be turned on to come out of standby.
Off the top of my head, pin one needs to be connected to pic 3 to wake it up?
Don't quote me on the pin numbers - if the smoke gets out it's your fault, not mine, OK?
MY DM was showing UCO error in the screen i have re-flashed it using original firmware through serial and then network cable
it starts to show boot with certain IP address and then LCD show at the bottom *STOP"
I first thought it is the Tuner but am not sure if it is only that, the problem is the Tuner that I have is ALPS bsbe1-701A 6613cb1g which is not commonly available
I have noticed that tuner gets really hot after powering the DM for some time
I checked the output voltage in the power supply
Starting from Right
pin 1: 25 vdc
pin 2: 3 vdc
pin 3: 3 vdc
pin 8: 5.5 vdc
pin 9: 7 v dc
pin 10: 15 vdc
pin 11: 30 vdc
pin 12: 3.3 vdc
pin 13: 9.4 vdc
As per power supply DATA sheet from Panasonic i should be getting 12 and 21 vdc in some of the pins which seems to be missing
BTW MY DM 7020 si is original not clone
Any help would be appreciated guys

Well am sure it is not on standby mode coz when you disconnect the power output leads from the main board you don't get any voltage on most of the pins
anyway thanks for the reply
Correct. Thats becuase when the plug from the main board is removed it WILL be in standby
The main board tells the power supply to come out of standby.
The main board does need power to idle on standby however.
Thats why only some pins have output when the supply is disconnected
Check the hard drive connection with a multimeter for it's +5 & +12VDC & you will see what I'm saying. Thats how they turn the HDD off when it's in standby - By switching off the not required rails.
If you don't belive me, follow pin 3 on the supply back to the opto & draw out the circuit

just a small point - all the latest original DMM Enigma 1 OE (DM500+,600 & 7020) firmware now all have clone detectors in it as do many of the the 3rd party software providers - for what it is worth.

Did you ever get your problem fixed ?
No jimbo I have not fixed the problem yet.
My tuner gets really hot as well as an IC next to it when the box power turned on, I bought a new tuner but i have not installed it yet. the reason is i don't believe it is only a tuner problem there is something else
I read what you have been answered on you similar Topic that
LNBP21 IC could be the reason, any advice on how can i test this chip and where can i get it
Thanks mate.

check out this thread. There is a link to ebay for that chip.

Thanks guys for your advice i have downloaded the data sheet when i get home i will test the LNBP21 and will let you know
well after intensive checking it is not the LNBP21 i believe the problem in IC 71 with no XC9572 XL which set just next to tuner on the (MB) i will buy new chip and see what happens any recommendation for cheap place to buy this IC from
it's the tuner, or the daughter board attached to it.
UCO says the firmware cant find any tuner installed.
Have fixed mine with same fault a year ago.
Also the LNBP21 has a driver chip alongside it that often fails.
bet you didn't earth your LNB like the manual says to

I'm feeling generous tonight.
Here fix it if you can....
Jimbo above changed the tuner already. Any other ideas?
Cheers,

Yep...get him to change the daughter PCB.
and check his work....maybe he didn't do it quite right.
Do NOT fit a screw on the back plate to hold tuner in.
(even though a hole is drilled)
It's an IC2 bus error, so tuner isn't communicating.
Of course PSU could be stuffed by now as well.
It will need areflash after atuner fault.
Put original DM image on.
Did he fit the correct tuner...the list goes on....
bye....

I didn't have one at the time,.. but I now have a daughter board with a fresh tuner already mated up.
Was very careful,.. think I did it right.and check his work....maybe he didn't do it quite right.
I'll now remove itDo NOT fit a screw on the back plate to hold tuner in.
(even though a hole is drilled)
Been replaced.It's an IC2 bus error, so tuner isn't communicating.
Of course PSU could be stuffed by now as well.
Now this I haven't done.It will need areflash after atuner fault.
So are you saying that after a tuner fault is picked up,.. a re-flash is required before it ever clears it ?
Is this part really that important ? i.e. being the original and not something else,.. say PLI image ?Put original DM image on.
Numbers on the sticker were identical.Did he fit the correct tuner...
Without comments from those that are in the know,.. its not that straight forward to sort out.the list goes on....
Thanks for your comments.
Jim.....
Thanks for your advise Prollyzed, i will check the driver circuit of LNBP21 any how mean while i will order XC9572XL since am almost 100% sure it is malfunctioning it gets extremely hot and output dose not look right
it seems that i have to change every and each IC on the (MB) to get it solved
just to give an idea how it looks like below
