I had some trouble with the unit a number of months back. The protection circuit(red blinking light) would kick in. I took it to an authorized repair shop. He fixes thing at the component level. He replaced a bunch of the small capacitors. He said the ones they used were cheaply made and junk. The unit has been working fine over since. I think he replaced about seven. That was all he said he had to do.
