I have posted this elsewhere to help a few guys, and was mentioned in one of the threads here. I'll re-post it if you haven't seen this yet.
Hello,
I'm from the U.S. where the OpenBox has become popular, but many have had a lnb voltage problem. If you are having this problem in the U.K. take a look at this fix I came up with.
I've traced the problem of low LNB voltage that causes the S-9 to work for a while then
drop off. There is a small part that looks like a disc capacitor near the tuner that actually
is a PTC thermistor that goes bad.
This part provides short circuit protection, but when bad it trips off at loading well under
the max rating of 500ma. The two bad ones I have found so far are marked M60 065.
On my own OpenBox that is still working, this part is larger and is marked JK60 065.
Digi-Key engineer crossed this to a "Little Fuse" brand part # 60R110XMR
This part can be changed from the top side of the board. Just snip the old one off.
Then tack solder the new one to the solder pads.
I then tested the S-9 by operating into a variable power resistor.
Ran it at 19v. @ 460ma. For two hours. The voltage and current held and the thermistor
ran cool.
It has been confirmed that this Digi-Key part will fix the S-10 with the same low voltage. It is located on the tuner board.
I see the part is available from Digi-Key/UK
PTC 1.10A 60V RESETTBLE KINK AMO - 60R110XMR
or from Digi-Key/US
Digi-Key - F1993CT-ND (Manufacturer - 60R110XMR)
Cheers
