Yuriy. I had a close look at my dead board and it appears you are correct. The voltage regulator has a tiny hole burned through the top. I tried to buy a voltage regulator to have a go at repairing my board. I cannot find one of the texas instruments ones here in Australia and the alternative you suggested is $0.99 cents for ten but the shipping is $14us. The chinese ones on ebay are designated 1117 3.3v 1A sot223. Not 1C as in your recommended replacement. Will these work? I would like to have a go at repairing the old board just for my own education.
