Hmm... There's a manual for a URC 11C-8/8A
in the files section, but the Samsung TV codes it proffers don't include 064 or 350. I subsequently found a 12A manual on Scribd
, but as expected the TV codes (seemingly all makes) are the same.
As it stands, I cannot understand how it is you are using 064 and 350 and can only suggest you try the codes listed in the above manuals.
