LX200 Classic Doesn't Power-Up

After about six months of not being used, last night I setup my 10” LX200 Classic and it didn’t power-up. I used both the A/C & D/C adapters. I also checked the fuse behind the face plate and it was okay. I also replaced it with a new fuse with no luck. I went online and read that this seems to be somewhat common on the LX200 Classics after not being used for some time. However, it appears that most experienced blown fuses, which mine does not do. My question is, could it be a faulty power switch? Previously, I had an issue with the power switch on my CG5. Any comments and / or suggestion will be greatly appreciated. Thanks in advance

I had the circuit board checked out and the power switch is okay. Also, when the circuit board is not connected to the telescope, it turns on fine. However, once connected to the telescope, it blows the fuse. When I turn it on, the amp meter on the face plate lights up all the way, then it goes blank (blown fuse). As I mentioned on my initial post, I found some info about the problem I'm experiencing. However, there wasn't much explanation on how to fix the problem. If anyone can provide some guidance, I'd really appreciate it. Thanks again, Paul
