We have a Meade LS telescope. When power on ... no sound or instruction is heard ... the hand box only power on with red background led but nothing is appeared ... what the problem


Two possibilities- corrupted firmware and or a bad hand controller cable. Re-load the firmware; if that does not do it then get a new hand controller cable. Beyond that it will be bad electronics inside the scope and it will need to be sent back to Meade for repair.

I have a 1998 Meade LX200 classic that blew out fuses and capacitor(s) when I recently started it up. I have had a local TV repair shop replace all of the capacitors and it now has a runaway RA drive when...


Something else is wrong. The first thing to try is a new DEC cable and a new hand controller cable for the runaway slew, and hand controller issue.

If new cables do not fix the problem then contact Ron Sampson on the Yahoo LX200 group-- just post a message for him there. He can repair Meade electronics at a reasonable cost if you send him the boards.

He can also repair the hand controller including the internal ribbon cable and the LCD screen.

Try the new cables first- check this web site for a wiring diagram:

or contact www.scopestuff.com they may have one already made-up.

No power hand held no light on display


Make sure the batteries are good. The cable to the hand controller may be bad. You can get another cable from either Celestron or a local dealer.

If a new cable does not fix it, then either the hand controller is defective, or something on the internal circuit board. It must be returned to Celestron for this type of repair.

Can you reverse the cable end to the hand controller-- a bad cable can cause this. Also low power supply, depleted batteries can also cause this.

Return the hand controller for replacement if batteries and or a new cable do not fix this.

Celestron NextStar 80 GTL hand held problem, tried to


You obviously burned out something inside. Many of these scopes require a proprietary style 12 volt plug with the correct polarity ---

My only suggestion would be to contact celestron and send it in for repair.

Power problem on lx200gps telescope


If it's an electronic problem --- there are several folks on the Yahoo LX200 Group that can repair the board-- go there and ask for "RON"---

You should be using a stable 12 volt power source. The only other thing to check are

Get a temporary replacement for the hand controller and see if that works-- and-or get a low cost replacement hand controller cable from www.scopestuff.com and try the old controller with a new cable --- usually one of the capacitors is fried.

The LCD display on the handheld remote seems to be "fading". I'm running it on AC current, so that shouldn't be the problem. Could I have mistakenly turned off the display? Please...


Probably too late, but you can change the brightness on the display. You may have accidentally turned it down. Let me know if you still have the problem and I can tell you how to access the brightness function on the hand controller.
