Dreambox 7025 Motorised issue

[jimbo69jones]

Has anybody else suffered problems with the 7025 not being able to operate a STAB Motor?

I've tried both tuners and it did work intermittently for a short time, but it's now not working at all. Have replaced the motor, no change. Tried another make of receiver, and that can operate the dish no problems.

I bought it 12 months ago from Satshop.ch and the first one they sent was dead on arrival. After a lot of messing around, I finally got them to exchange the unit (by ordering a technisat HD card, which they still charged me 40 swiss francs to deliver bastids!)

I reckon its something with the power supply to be honest. Don't suppose anyone has taken voltage reading from each output so I can compare them?

Thanks

I can't be sure but I think it's 3.5V from the output of the tuner to turn the motor. It should say in the motor manual.

Have you tried another image on the 7025?

[jimbo69jones]

Thought the tuner sent pulse codes down the wire for the motor to pick up?

As for the images i've tried them all Currently it has LT fourth on it.

DIgital Satellite EQuipment Control 1.2 or DISEQC 1.2 is a method of communication between set top box and motor. The power used to turn the motor is the same power used to feed the LNB. That is why DISEQC motor are slower and less powerful than the 36 volt motors.

What settings are you using for your dish control in the 7025?
Are you trying to use USALS or the Goto X function in the dreambox?
Does the dish move when you tell it to move ease or west with the remote control?

[jimbo69jones]

Tried every conceivable setting. When it did work, It was by inputting my longitude/latitude so USALS. Like I said, it has worked in the past, just not any more. I bought the dreambox and didn't have much chance to play with it, but now I want to get it running properly.

And no on the east-west question. Nada zip squat.. Actually, thats not quite true. I took the motor off the mount, and brought it into the house. On a short piece of cable, it kind of works. It will turn for a little while, then the command status light on the motor goes from green to orange. I'm sure that means an error in the data received, or an undercurrent error.. Either way, it doesn't work properly

I had the same problem with my 7025 when i first set it up
changed all the cables and connectors up the ladders about 30 times
to reset the motor still not working
the dish used to move once then power from the tuner failed ?
pulled some more hair out then decided to get a tm1500+
took about 30 mins to setup
reconnected my 7025 and yes that was also working now
until recently i was just out of warranty then the PSU blew
I dont know if this helps but DM7025 are known for PSU faults

Yellow powersupply change this:
C8 2200uF 16V or 25V
C2 100uF 25V or 35V
C5 47uF 25V
C26 100uF 25V
C27 220uF 25V


Green one change this
C8 2200uF 16V or 25V
C2 100uF 25V or 35V
C5 47uF 25V
C26 100uF 25V
C27 220uF 25V
En C36 100uF 25V or 35V, you find it under the Alu case


For the green power supply REV 0.2, i think these ones but not sure:
C23, C36 et C38

can some one confirm for the green REV0.2 PSU?????
