I have a problem with my father's LX200. It has been fully functional for 20 years, but when I turned it on one month ago I found this issue:
When I turn on the power switch the test test leds and the one on the power supply light up for one second and then they all light down, and if I retry to switch on the telescope seems dead (power supply too), so i have to disconnect power supply from the telescope and power grid and wait about 30 seconds to be able to retry, but with same results.
I've been looking for similar issues on forums but I didn't find the same problem. I checked capacitors on main board but they all look good. Perhaps C3 of the control panel has a little stain.
I attach pictures of all, and I would like to know if the power supply is the original one or an after market model, because I read that there are problems with original ones.
