Hey, I finally did something that I should have tried earlier -- I googled the MT-Logic company itself. It appears that, like many other TV brands, they don't manufacture their own devices. The chance of finding a good config file would go up if we can find the original manufacturer of the TV.

It seems that the LE-427118MT was sold through Aldi, but that company doesn't manufacture TVs either. I've found a note on a forum board that links MT-Logic to "Audiosonic", and from there to "Tristar", which is apparently a company doing manufacturing in Turkey. Let me do a little more digging.

Also, if you haven't already, could you run the "Automated Keyset Search" and see if Pierogi already has any keysets that might work with the TV? Thanks!
