The problem could be anything from bad connections to a faulty handset.  Since you got it from an estate sale, there is no guarantee that someone hasn't opened it before you and fiddled with the insides.  Are you using an adequate +12v PSU?

You can buy replacement handsets, but i suspect this could cost more than you paid for the whole thing.

I’m using the standard power supply it came with. Just 8 AA batteries. Opened the remote up and made sure everything was put into place correctly, still did nothing. Fortunately, I got everything for $60, unfortunately, the remotes I’ve found online have been around $70-$80. Do you think a firmware update could possibly be the issue?

Good evening. I recently got a Celestron Nexstar 80gtl from an estate sale. Everything on the telescope itself I a good, but the remote is not working. I plug it on, and the red LED turns on, but I’m not getting any text displayed on it. What could possibly be the problem, and hopefully the solution?
