Are you powering this on with all the solder blotches everywhere? If that's how it was returned after repair I'd be asking your repair guy some questions, it's pretty sloppy.

Edit: After reading again, it sounds like these may NOT be your actual boards, hopefully that's the case!

What do you mean by, "I change plus and minus"? If you did that, that's your problem. You know doubt caused futher damage.

Take the criticism as constructive. If you want to repair this yourself it's certainly possible, but first step is cleaning up all the solder blobs. If you did cross the positive and negative wires you may've blown up the surface mount chip, which is about impossible to replace with a soldering iron.

Nobody is being critical, least of all me. Just trying to understand what your problem is--I understand that English is likely not your native tongue.

i use hot air , but im very confused about U2 , the electronican put the regular stabilizier LM 7812 (3 leads) , is it make difrence using 3 leads instead 8 leads integrated , AUTOSTAR was working same with two diffrent stabilizators
i use it soldering iron only for bypass the burned lines on a board ,
and i hope i will find new one or old board but functional ,
this is second time i switch wires , first time was repaired , but second time didnt survive , electronician told me that PIC is burned,

MOTORS ARE NOT RUNNING , AUTOSTAR IS WORKING , i switch plus and minus on the battery , first time explode the capacitor and some circuit lines , and also i get notification on the autostar MOTOR UNIT FAULT ,
this time i dont receive that message , i also switch plus and minus on the battery and when i notice that i make same mistake when i rewire motors stop to work , i test motors by direct power supply they work ,
doesent track , drive , calibrate , train ,
and i dont see mine telescope model in the AUTOSTAR menu , data is lost or AS cant read it from board

I would first try Meade, but I have no idea how old this mount is, or if they supply parts like this. I seem to recall a website that sells parts but can't find it at the moment, hopefully someone else will be able to provide some ideas.

This mount is old around 14 years , i contact meade , but they dont have spare parts , its older version , single armed , when you see it looks like DS2000 mounts , Meade sugest me to buy new mount , but i dont know does AUTOSTAR will be compatible ,
i clean everything you told me , but i burn the board little with that hot air ,

I am curious.

8 leads for a voltage regulator? That surprises me. I once had a voltage regulator with many pins in a very old audio mixer, so I guess it could be.

Is the original part marked with a number? (U2 is just the location on the board, not a part number.)

And my other comment is, sadly, that I agree with Uncle Rod and others that you probably blew up more than just the voltage regular. I guess chances of fixing it are bad.

You should ask a mod to move this to the Meade forum.
