telnet using PuTTY
I am writing to you again...Open your eyes or take off your rose-colored glasses... and go to Johnny's forum here in this topic and look at the correspondence with a user who can be said to have had exactly the same problem.. https://jb8a8f8.com/support/in…900-uhd-only-led-red.785/
Thanks Team, for your support, just small addition; the box was working fun but after a power cut it got stuck in halfway sartup, and then afte r several attempts it ends up to this status...
From which team was the image installed in your receiver before it crashed?

I am already looking there, Many thanks for the guidance...

Yes, of course... 
if you want to play some more, then here's another topic for you to experiment with OptiFlasher Pro [DMips EDition] For DM520/DM820/DM900/DM920/DM7080
https://www.yassinov.com/forum/forumdisplay.php?fid=69 this is the author's forum, and you can play with your problem there, but I assume that you will not find an answer and a solution - only to the service center. 
https://www.domica.biz/index.p…15938.msg175698#msg175698 here's an option for the experience, it's true for a clone, but it doesn't matter, the original can also be restored. The forum is Russian, so use an online translator.
please give this a try:
open the top cover of your dreambox, switch on the dreambox from baby switch while lightly keep on pushing the heat sink, if the display comes in slightly pushing mode ......then your box can be recovered by yourself, hopefully
then your box can be recovered by yourself, hopefully
this means that you need to do reballing of the CPU and in no way will it be able to do it on its own and quickly... 
Open your demo, and press your finger on the processor cooler because it may be missing contact with the motherboard. Well start by holding your hand on it
but I'm starting to think RAM is defective
Above in the topic, I wrote the reasons why there may be such a malfunction.According to the log that he provided, it is difficult to say since it is clear that neither the processor nor the memory is determined and there is no connection, that is, there is no request from the central processor to read data from memory .. and it is difficult to judge unequivocally that this flash memory is faulty. There may not be one or more voltages that the processor or flash memory uses.As a result, the login will be empty.And what you are suggesting is to press down the processor or memory, this detachment of components from the board is called -the medicine is reballing to solder off the problematic chip, roll the balls and solder them back. And if it can, suddenly the receiver will start , then it will not be long before the first complete power outage from the mains .The way out is to take voltage measurements, compare them with those screenshots that are on Johnny's forum. Then the circle of troubleshooting will narrow down .But if the owner of the problematic receiver does not have skills in repair, a radio equipment repair service center.
Display MoreHello Team,
I'm experiencing issue in rescuing my DM900UHD box, as of Now it is not booting and stuck on fixed Red Light no display on oled screen.
PuTTY gives me the below:
Dreambox DM900
AVS init...
AVS init OK
CPU 01
Dreambox DM900
AVS init...
AVS init OK
CPU 01
Dreambox DM900
AVS init...
AVS init OK
it keeps repeating indefinitely
Please help to rescue my box.
for info I tried with Optiflasher software and it gets stuck on "DM900UHD Detected! " only...
Best Regards...
ok , when you conect box with mini usb com port in dream up , what is show on ? dont use ip , only com port , box is conected?
I have another idea:
I have another idea: Open the Dreambox 900 when the power is off - and unplug the ribbon cable from the display to the motherboard,
wait a bit and then plug it back in, switch the box on again. maybe it will start now
but I'm starting to think RAM is defective

Because It already happen to mines and it easy to test.
