I have an EEOS300A model micro-scope that wont turn on with or without the adaptor and/or battery. It hasnt been used in a long time so I dont know if sitting killed it. I opened it up and saw 3 LED lights. With the adaptor plugged in 1 light would stay lit. When I tried to turn the unit on the middle light blinked. I tried a different adaptor and it did the same thing. Any suggestions, besides sending it in for repair? I really need it for 1 last test to fix a motorcycle... Thanks.
