Hello and some background - my astronomy is mostly visual with some wide field photography - I'm retired Engineer (Electronic) living 400m from the Indian Ocean in South Africa although I have access to the Karoo region for my viewing. However...
My trusty LX200 GPS EMC of 10-12 years vintage damaged the loom between arms and base board to the point where the fuse blew on the 12V supply and the handset died. In analysis it seems it somehow managed to pick up +12V line in the aluminum interrupter plate ripping it out the connector and waving it around. I have determined the front panel electronics are damaged to the point where it draws 100mA instead of +-5mA. The 5V LM2931 regulator goes into thermal protection mode, I did replace it, no change. Due to my location in South Africa it is not cost effective to ship anything anywhere for repair, it’s DIY or nothing.
Is there a viable source of replacement/refurbished main boards for this model although I have access to SMT repair facility but I am loath to dive in the replacement of SMT components like the RS232 drivers and glue logic only to find the HC11 or PIC is blown and not available in the programmed state. The reports of Meade’s after sales service do not seem to be very complimentary!
This is my first query I have a plan “B” but want to explore the above option to its limit. Thanks for your attention and input.
