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.

Can I just swap out my meade 492 motorized mount remote for a used 494 autostar remote or 497?


It depends on which model Meade telescope you own-- you never said?

Yes you can swap a 494 for another 494-- but we need more information to be able to say a 497.

I have six Meade ETS-LX 6" telescopes which are used in an introductory astronomy lab. I have upgraded the firmware and other files in three of the six and they are working fine. The other three do...


These scopes have many bugs in the firmware and are not a mature technology. Some people have issues and some do not.

About the only thing you can try is to reload the firmware using the SC CARD method. Contact Meade or read the manual to learn how to upgrade the firmware using an SD flash memory card.

Other than that the scopes will need to be returned to Meade for repair.

I have an older, let's say "classic" LX-90. My


You can try Three things:

1. Do you have fully charged batteries-- or a good power supply.

2. Sometimes the cable to the hand controller needs to be replaced

3. Execute a RESET on the hand controller and reload the firmware--

If these do not fix it, the hand controller is defective and must be replaced. You can find a used 497 controller for about $80 on AstroMart.com

and Meade can also sell you a new one.

ETX-80 hand controller say's "Self Check Failed"


You may need to reload the firmware by following these instructions for Safe Load:

From the Autostar 2.0 README file: "SAFE LOADER MODE IN YOUR Autostar:
If the firmware in your Autostar crashes and you cannot access the "DOWNLOAD" menu item on your handbox, you can use the "SAFE LOADER" feature of your new Autostar software (version release 1.1G and above). To get into the safe loader, follow these simple steps: 1. Make sure the Autostar and ETX are turned off.
2. Press and hold the "ENTER" key and the Scroll Down Key located to the right of the help key on the Autostar handbox.
3. While depressing both keys, turn on your Autostar power switch. This will require you using both hands.

You should see "FLASH LOAD READY" on your display. This indicates that you can proceed to Update new software to your Autostar."

This is for the 497 controller. There is NO safe load for the 494 controller.

Power pack creates 'hummmm' in wireless headphones.


I don't think the 12V power pack is the problem. Generally there would be a regulator on the plug pack input to the transmitter (as power packs are notoriously bad at voltage regulation).

My guess is it an 'earth leak' between the TV and the transmitter via the audio lead. Does the powerpack have a earth pin. If so, are you able to plug it into an non-earthed power outlet.

If this isn't possible try removing the ground connection from the audio lead.

It could also be a bad audio lead.

Is the TV mono and the transmitter stereo or visa versa? You may need a mono to stereo lead.

Hopefully something in here will help.

Meade LX200GPS 8" won't initialize on power up.


Try doing either a garbage collect or a safe load-- and then reinstall the hand controller firmware--

Instructions-- depending on the type of controller
Autostar 495 or 497: You enter Safe Mode by holding the [enter] and
[scroll down] keys pressed when you power up the telescope. The
Autostar will say "Flash Load Ready"... now go start the ASU.

Autostar II: if you need to use Safe Mode to recover from a disaster,
turn on the telescope, and key 999 before it says "Initializing"
The Autostar will say "Flash Load Ready"... now go start the ASU.

LX200gps: BEFORE proceeding further, click on the OPTIONS item on the Top Bar.
Now click on "Garbage Collect Hbx" ... this will perform data cleanup
within the Autostar which will avoid potential mess-ups.

ETX-125 Autostar controller not working


I assume the small red light on the power panel is ON. ???

If it is the scope is receiving power--- check to make sure the cable from the hand controller is plugged in properly-- jiggle the cable to see if you have a loose BAD cable. Before you panic --- try another cable or reverse the ends ---

Before you buy another hand controller try a new cable-- scopestuff.com sells a nice long flexible one for the 497 hand controller.
