URC-7962 no response, no lights, uploads and downloads

Oh boy, do I need some help here, folks. I have posted my latest download here http://www.hifi-remote.com/forums/dload ... e_id=12555. I got a new 7962 about a week ago, getting back into jp1 after being in the harmony world for a while. I was trying to get this new remote to work for the wife and kids, and I was almost there. Had it turning everything on, and turning everything off using a button I didn't want to use. I was trying to get the Power button to run the macro, when BOOM! Well, not literally. I guess just the opposite. No lights blink, no button presses make it respond, but I can still upload and download.

I tried reloading an earlier file, didn't work. I tried taking all batteries out and replacing them, didn't work. I tried taking out batteries and pushing every single button on the remote, nope. Batteries out, let it sit overnight, nada. I need some help from some software folks, I think. I'm a hardware guy, I could take this thing apart, and troubleshoot, but I sure am hoping not to have to.

Please someone take a look and offer some suggestions. Thanks.
Jim

This sounds like a hardware problem to me. My understanding is that the power supply during uploading and downloading is provided through the JP1 connector, so it looks as if what has happened is that the battery power has somehow failed while things powered through the JP1 connector still work.

The only way that software can cause a lockup like this is if the firmware has been corrupted. Uploading a bad setup normally just causes a software reset. There are protection mechanisms in the firmware that would prevent a bad setup from corrupting the firmware, so I cannot see how it can be a software problem. Sorry.

Thanks for the reply. In some ways I was hoping it was hardware, and some ways not. It doesn't look quite as simple to disassemble as the old clamshell types. I should be able to get to this soon. I will also post my findings once I find something.
