20 Most Recent Meade ETX90AT Maksutov Telescope with UHTC (cat35140321) - Page 9 Questions & Answers


First thing to check are the hand controller cable and the DEC cable.

scopestuff.com sells these. Replace the cables. If it still does not work then it is an internal circuit board or motor problem.

Could be anything from a bad hand controller cable, LOW battery power, or a blown out hand controller.

Check the cable and the batteries first.

It may be looking for the GPS satellite. If the scope is already broken, RETURN IT NOW!

All of Meade's manuals are on this web site:

Look down the right side of the page for the Polaris header.

This is a known issue with the older ETX scopes. You can use silicon sealant or a small amount of hot glue -- and just put the mirror back on it's small platform.

However you might need to disassemble the rear of the scope to do this. See this web site for instructions on disassembly.

You may have Corrupted firmware in the hand controller- that's why they want you to do a RESET.

You might have to reload the correct firmware to fix this problem.

I believe if you hold down the ENTER KEY and the SCROLL DOWN arrow key and then turn on the scope you enter SAFE LOAD where you can reload the firmware.

Tnis is the altitude clutch- it's either broken or has grease or oil on it.

There is a small spring inside that sometimes gets STRUCK DOWN-- this automatically turns off the internal batteries, as the scope things a separate 12volt power pack is plugged in.

Get an external 12 volt power pack and the correct 12 volt cable, and power it up.

If the light comes on and it works the switch is broken. Not really a problem as you should always run a goto scope on a separate power pack.

These parts are only available from Meade, or if you find an old scope on astromart.com that is being torn apart and sold as parts. You might find a replacement gasket at a well stocked hardware store--- maybe?

I seem to remember it was about $100 plus shipping. The 80 is a completely different telescope style-- the 90mm is a Maksutov Telescope.

If it is not written on the tube ???? why would you need it??? Many scopes DO NOT have a serial number but most have a name like

Meade LX200

Celestron CPC

Meade PE 125

and so forth.

Meade has all of their manuals on this web site:

http://www.meade.com/manuals/index.html

You never said what is the NAME of the scope. Anyway find your telescope on this page and download a free manual.

The LARGER the number written on the eyepieces the LOWER the magnification. Start out with the eyepiece with the largest number written on it and practice focusing on a distant object during the day time.

A fellow by the name of Ron Sampson can repair hand controllers and main boards on Meade telescopes. He does very good work. All you need to send him are the board(s).

You can contact him by posting a message on the Yahoo LX90 or LX200 group forums.
http://tech.groups.yahoo.com/group/lx90/

Good luck-- by the way he repaired the hand controller for our astronomy clubs 10 inch Meade LX200, at a very reasonable cost.

Did you also break the focuser?

If not contact Meade for the exact replacement at this web site:

Meade Optics | Answered on Apr 21, 2010


You never said what brand of telescope you have or what type.

Put the eyepiece with the largest number written on it into the focuser. Practice focusing on a distant object during the day time. The moon should be your first target at night.

It's a brand new telescope! Or you can attempt to reinstall the Firmware following the instructions in the user manual.

Meade Optics | Answered on Mar 22, 2010


Hi.

I am answering because I see that the problem is still unsolved.

I think that the best thing to do is contacting Meade, so that they can tell you if it is the case to replace the pcb, or if it is just a setting problem.

Here the contact: Contact Us.
