I've got hold of a Bush BFSAT01HD, in the hopes of repairing it and ditching Sky and saving some money. Also HD would be nice on my trashpicked 42". This is a HD Freesat receiver (for receiving free-to-air satellite, about 150 channels.)
It's stuck in standby. Blue LED lights on the front. Pressing button does nothing. All other buttons inactive.
It takes a 12V power supply and that works fine. I've used one of my own known good ones just to make sure.
All switchers look good, core voltages are okay. (6.8V, 3.3V, 2.6V and 1.25V.) All LDOs test good. (Only two on the board, one for analog stuff I think and another for the DDR termination (a special type of LDO?))
Full of cheap TAICON but none bad on first sight. Ripple on rails is pretty low, within acceptable margins.
Main processor gets slightly warm (big heatsink) but that's it. Nothing else.
LNB voltages are no where to be seen, but I don't expect they will be in standby.
So I began to suspect a firmware/software problem - looked it up and apparently a lot of these boxes have been bricked by a botched over the air update. It's got an RS232 port on it, so I suspect I can update the firmware through that, but I can find NO instructions anywhere on how to do this... Bush is completely useless, but what else do you expect from Argos?
Also, there's a connector for SATA.
It's very tempting to drill that out and install a SATA connector, then wire up an e-SATA drive. With firmware from another box, maybe it'll work with the drive
. Dirt cheap Freesat recorder.
