Problems with my LX200 Classic version

Hi, I have a serious problem with my telescope Meade LX200 Classic.
I would ask you some opinion about my problem.
Today, when I turn on my LX200 the C1 and maybe C2 capacitors are burning.
I don't really know the reason why.
I hope that the problem is only on C1 and C2 capacitors, but I'm not sure.
Looking at the Power Panel schematic on http://www.ccdguy.com/lx200_images/PowerPanelSch.pdf it seems that the C1 and C2 capacitors are supplied from a +12V that arrives from the Keypad.
It is possible that the real problem is the Keypad?

Sorry for my english.

I hope that yuo can help me.

Regards
Nico

    I have the same problem except that it is the C8 capacitor on the main pannel. I think I can replace this but I'm not too savy when it comes to ordering capacitators. My scope is a Classic lx200 8in.

C1 and C2 are on the input of a voltage regulator. The fact that they burn, could mean that their voltage rating has been exceeded (check the voltage across them), or that age has caused their failure. The classic uses about 18 volts into the power panel - see that it is not higher than that. The handpad would not be a cause for this to happen as it is not the source of the power. Replace the caps with similar ones, but with higher voltage rating - 50v is fine. But check your power supply first!

Meade lx200 acf r manual


Many Meade telescope manuals are available here: http://www.meade.com/support/manuals/ . There are several models in the LX200 series. The manual for the LX200-ACF is here: http://www.meade.com/downloads/dl/file/id/11/product/0/lx200_acf_manual.pdf . There is also a model LX200-R; the manual for this model is at http://www.meade.com/downloads/dl/file/id/13/product/0/lx200_r_manual.pdf . I don't see anything about a model with both the ACF and R features in this series.

I hope this helps.

10"LX200 EMC that will not


This model LX200 classic has weak capacitors that blow out with age. Go to the Yahoo LX200 group-- post a message with the problem for "Ron Sampson" he can repair the board if it is broken. Also Dr. Clay and Andrew also post to this web site--- they know a lot about LX200 electronics.

Capacitor upgrade for classic lx200


I don't know why these are burning out but if you stayed with the same type of capacitor with an increased voltage rating it will most likely help.

Cannot power up my Meade LX200


Check to make sure there are no bad connections under the swith itself. My Celestron C8 mount has similar problems and if I mess with the switch it will power up.
