I was just playing around with some settings (between my HD 500 and my DT 50 212). I decided to

disconnect the POD and play straight into the DT 50. I put the amp on standby, disconnected the L6 link,

then plugged my guitar into the "high" input (Les Paul w/ regular humbuckers). Now topography III sounds

really weak and scratchy/slappy. The other topography's seem to be okay. But something is definately wrong with III.

 

I reloaded the newest flash upgrades, shut down, an restarted with no change.

 

Any ideas?

Don't know exactly what you're hearing but I'm sure you know each mode has it's own volume, etc.  Mode III should be one of the louder ones in my experience.  As strange as this might sound, try turning the master volume all the way up, and use the channel volume to increase your actual volume from the amp directly with your guitar plugged in.  Also, try switching channels and every other switch...triode/pentode, etc.  I'm sure you got the idea...and see if mode III sounds the same in both channels.  I've come across some very quirky bits with these DT50 amps and volume has been one of them varying greatly between modes.  I did this type of "fiddling" around and the amp finally settled down - so to speak and has been running consistent since.  Kinda like a race horse in the starting gate...how's that for a comparison?? 

Take care,
