Hello everyone,
I am also t trying to fix such a beast... Problem is that a bad dish motor burned a bso300n03s (like blown gate, that bad), next to the lnbh21pd and I replaced the n-mosfet with a bso110n03ms (double the current).
The thing is that the entire PSU rail (input 12v/3a) is now at about 2.89v and constantly dropping to 2.5v, more than 3a being consumed...
I then noticed that the new MOSFET was heating like hell and I then desoldered it... Dreambox seems to start, a couple red LEDs remain lit, the yellow/green front led blinks then in another try the front red LED blinks, but the problem is that the input stays constantly at 1.5a and the lnb21hpd hearts very much (not as much as the MOSFET, yet very much)...
How can I fix it? Anyone has any ideas? Should I change the LNB21? What else should I check?
Thank you in advance!
