MiniTiouner Express schematic.

Was there ever one available? I'm trying to fault find on a Rev B. I can't see anything on datv-express.com.

Google came up with a post by F6DZP from the French DATV forum that implied the tuner was an exact copy, so perhaps if that was the case and the fault is not with the 1.1V/3.3V supply, you go with the original and it will be close enough? http://vivadatv.org/viewtopic.php?f=80&t=669

The MiniTiouner-Express is the exact copy of my schematic, the only "creation" of the author is how it produces the 1.1v and 2.3v.(very creative).
I have been obliged to help the author that did not understand how a MiniTiouner works, he has just made a copy of the schematic given on Vivadatv forum(Minitiouner and MiniTiounerPro) and has just removed the LNB power supply and other extensions.
So when I read on the documentation that they have "developed" the MiniTiouner-Express that make me smile.

Thanks. Unfortunately the problem is in the power supply.

I hope you heard all the rumble about corroded jumper pins.
Apparently the older express jumpers have given up to work and supply the power to the units.

Thanks. I hadn't heard that. This one is OK though.
