Bought this when they first came out in the 80's. Used for several years but then got put in the attic about 15 years ago. Worked fine when it went into storage. Pulled it out today to use and when I plugged it in and turned it on, all I got was a steady clickiing like a relay. About 2 clicks\/second. No lights on the display at all, no response to any buttons. It was cold in the attic so I'm letting it warm up to room temp before trying again, just in case the low temp in the attic may have an effect on the power relay or something. \n\nIf anyone has any experience with this type of issue, would love to have some insight, ideas or where to start troubleshooting.\n\nThanks!
