Tonight, upon turning my 12" LX600 ON, i am faced with a weakly lit blank display,

the power indicator does not lit and nothing works :

 

I use a regulated power supply set to 12.8 volts, i read 0.5 amps on the dial, good solid connections,

everything was fine until tonight.

 

Used it less than 10 times.

 

I read 12.8 volts at the plug too.

 

Anything i can try or does it have to return to Meade ?

 

Thanks in advance,

This morning i installed fresh batteries, no joy : : :

same behavior as with power supply.(removed)

 

No storms during the period it was installed,

i have surge protection as well.

 

Only things connected to it is power supply and usb to computer (tried removing it)

 

Nothing i can try ?

 

Can't communicate with telescope.

 

It just died on me !

I do not know about an LX 600, but one general question, was the power supply polarity set up center positive?  With some of the other mounts, getting that backward will fry the board.  You did say, that you used the setup several times with no problem, so polarity is probably not an issue.  Just thought I would ask to make sure.

 

Can you call Meade at 800-626-3233 and ask Customer Support from Canada?  If not, let me know and I will make an inquiry about who you can call.

 

Hopefully, there is a fuse somewhere that has blown.

 

Sorry I cannot help you more than that.  Rest assured you certainly have my sympathies!

Hello Bill,

 

Thanks for your good words.

 

I contacted my dealer who will contact Meade.

It is under warranty.

 

Lets see what comes out.

That's all i can do.

 

Got a lemon it seems.

Cosmic scale frustration !

I understand.....been there with a different brand.  Hope it all works out well for you.

 

If you have the inclination, keep us posted on what transpires.  We can at least sympathize if we cannot help fix it.

 

Best Regards,

as with a lot of electronice its a hit or miss situation.Things dont like the sudden power surge.Its better than it was.I could be anything from a bad chip ir a loose wire.A lot of the chips are static sensitive so even if you had an electrical storm or a close lightening strike static can take things out.

Its the nature of the beast.

Hope you get it resolved soon.

Hi Mark, Thanks for coming back.

 

 I have a 1000 Joules power surge protector, do you think it is adequate ?

 

Power to the observatory goes through a timer in the house, so only when needed.

 

I also have an Optec TCF focuser, and a ST2000 camera on the scope, both are fine.

 

I think i was just victim of pure bad luck.

 

My emotions now make it possible to say how wonderful the telescope is, so i too hope it will be resolved quickly.

That should be fine for power surges.I use both cyber power and apc bps or battery back up power supplys in my OBS.

It helps for the electric power surges.

Best think to help reduce static discharges is make sure your scope tripod or pier is grounded well.

In my Observatory I have 4 seperate grounds.1 on the pier  1 on the scope base 1 on the 12 volt power supply for accessories and 1 on the computer.

I havnt suffered any damage since the addition of the grounds. If you are using things in the field i personally would recomment adding a ground wite to the tripod leg then using a 12 inch spike stick it in the ground for a ground.Then add the scope once the tripod is set up.Make sure ground is pushed into the ground them power up the scope.Every little bit helps.

Thanks Mark, that is useful information.

You can be sure i will take every bit of precaution and install good grounds as you did.

 

Meade should include these suggestions in their manual.

It seems to me the scope is very fragile from an electrical point of view, non expert opinion here..

 

11 days and counting, no reply from Meade, is this normal ?

With the change in the company im not sure how far behind in customer service they are.Personally id keep calling on a daily basis until you reach someone.A scope of that calaber and cost should NOT be sitting collecting dust while you wait on what could be a simple answer!

Great news today :D

 

My dealer email me that Meade is sending a replacement front panel !

 

Hope it will cure the problem.

 

Have been busy today installing grounds to 4 ' ss rod in the soil,

that should do it.

 

I notice that there is no electrical continuity(ohm meter) between starlock and the rest of the scope,

should i ground that too ?

 

Same between wedge and fork base, but there is no electronic components in the wedge.

 

So i have common ground to tube, forks and base, power supply, to rod.

Plus surge protection of course.

 

Next step is dew heater.

 

Most are PWM, that is pulse width modulation, pulses of DC voltage applied on an adjustable frequency, right ?

 

Pulses means scary induction in the tube !!!

 

Is it better to go variable continuous DC for the heaters?

 

I have not found such a unit so far, suggestions ?

 

Or i keep using my hair dryer...

 

What a joy it will be to see my scope working again :)

Hi JG, availability on these panels can be tight and I would like to follow up on it. If you call 800) 626-3233 and give CS your information we should be able to locate the panel order placed with your dealer. If you call please ask the staff to forward me your order and I will keep my eyes on it.

Hello John,

 

Its nice to see someone from Meade taking care of my problem, now that's customer service !

 

I forwarded your message to my dealer, Lire La Nature in Longeuil, Que.

 

I tried to copy/paste their link into this message, not permitted it seems.

 

Owner Stephane Broquet is taking care of my purchase, and i don't want to muddy things by intervening

in the process.

 

I will make sure he  follow your instructions fully.

 

Hope my scope will be back in service soon, it was so marvelous, very precise goto, and the best optics i have seen in my long

life as a telescope maker, made optics up to 30", built astrophoto gear, etc.

 

Unfortunately i was cut short trying imaging with it.

 

Thanks again for your personnal implication, it is much appreciated.

 

Jean Guy Moreau

Copy and paste here needs to be done via control c and control v.

As for dew heaters youll be ok the PWM is what is being done with the timer  chip.It sends bursts of voltage to the heater to determin temp.

Low setting will eend ex a 12 volt pulse every 7 seconds and a hight will send a 12 volt burst evert .5 seconds.They are heat regulated by the time or amount of time the 12 volts are allowed to go to the strip.
