    I thanks,

    Im from Portugal and i know that there is a dealer to meade. The problem is that they want all the telescope back just to swap an electronic control panel. Even with the telescope out of guarantee.;-)

    Hi,

    i think the problem was due to an inverted polarity, or a bad contact that was happening on the AC Adapter connector. I just opened up myself and i saw that there is a "fried chip". The reference for this chip is [ SI4947ADY ] from vishay. You can see the datasheeton this link -http://www.datasheetcatalog.com/datashee...

    You can see the picture form the fried chip on this link -http://oldfield.sinaman.com/star/lxd55/l...

    :-) Thanks for your help!! Do you think that is difficult to swap it for a new one? Maybe the best thing is to talk with an electronic understood....this solution still cheaper than send all the telescope to USA and repair...!Do you have an ideia where i can find it in Portugal? Are you from spain? Thanks

    Hi, sorry I thought you meant just the autostar controller that you can buy separately. I don't think you will be able to get just the internal controller board, maybe eBay but a long shot. You could try email to Meade in the USA & see if they may ship one? How did it get burned? I am an electronics engineer perhaps it can be fixed if you describe the fault?

    Hello Marco, Looking at oldfield's website he has repaired his board successfully by replacing the burned part which is the drive for one of the motors. I suggest you order the part & change it as they are only 1.25 euro here in Spain - but 30 euro shipping!! See link:

    Hi, you can order from the same company in Portugal:
    http://pt.farnell.com/jsp/Semiconductors...

    The shipping is really expensive just for one part.

    You can search the web for a electronic hobby supplier in Portugal or maybe in a big town or city you could find a shop that would order one .

    I suggest you find someone locally who can repair electronics as it is not a job for a beginner without the right tools. Perhaps find a technical college that teaches electronics or a repair shop?

    If you are really stuck you could send it to me in Spain!

Doubtful you will find just a reticle- for the polar finder. However you may be able to buy a complete polar alignment scope-- new-- or used on Astromart.com.

Best place o find out about that spring is on the Yahoo Group LXD55 tech group-- Post your question there as they have specific knowledge about that mount. And also look at this special LXD55 web site for many tech tips.

Electronics don't work. Sent back to Meade for a month. Received back from Meade last Friday. Still doesn't work. No lights, no nothing.

You do have batteries ?? or getting power from 12 volt power supply?

If yes -- and NO red light on the telescope control panel, then send it back again! They never fixed it!
