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, W60 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 # F1990CT-ND. 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. http://search.digikey.com/us/en/products/60R065XPR/F1990CT-ND/2690458 I ordered a few extra of these, I'll mail these out for free to people who actually have trouble with your lnb voltage. Just PM me with your request and address. Please not for "maybe I might need this" and set it on the shelf. Update: The part numbers in BOLD have been changed. Also the Digi-Key Link at the end has been updated Reason for edit: Pixl has been advised by another engineer that Digi-Key slightly over sized this part. The new part number is closer to the original specs.
