Unfortunately, there is not at engine start

operational problems at the netbook. PC Speakers whir louder than my old converters (no name for 40euro by nem truck stop in Belgium 7 years held). Operating at 34cm CRT TV is ok but then runs the fan even permanently with (a bit annoying because it's good to hear) and the image has slight Griesel (gabs the old converter only NEN strip slowly across the screen ran). Unfortunately I must say that it bothers me very much that when I start the engine of the converter "short" off (undervoltage?) ie tv, charger or go for speakers 1-2sek completely. I had this problem with any other device in advance that I have tested in the performance class. negative I noticed that the transformer has been delivered with signs of wear. He has so yes TZD full guarantee whatever. I think I'm going to the transformer over the weekend if I send back in the am back home and prefer to continue testing. otherwise solid quality workmanship. Conclusion: for netbook, laptop and Co certainly a top unit but I'm not 100% satisfied
