Question about Meade LX200GPS Telescope

1 Answer

My LX200 (1992 vintage) has apparantly suffered complete electronic failure. Having blown both the line fuse and the slow blow behind the power panel, I started trouble shooting and found: The ribon male connector on the power plate has a short between terminal 1 (18v line) and terminal 2 (12v line) somewhere on the back of the connector hidden from view. In addition the said 12v line is down to earth, either through the caps C1 and C2 or the plugs for Rs232 or the key pad. To locate these faults I had disconnected C4 , R1, D2, the 5V regulator and even cut the pc board tracks in a few places. With apparantly several faults on this pcb I assumed the main pcb could be faulty as well. Then I decided to stop further troubleshooting My question is what can be done. Is it possible to replace all the electronics? The scope has seen very little use, but may have suffered electronic failure due to extended expsure to slight humidity. The pcb appear in perfect condition though, ie shiny and no signs of track faulting. I hope this helps to describe my distress adequately. I hope there is a way out because manual guiding is not on for me.

Ron Sampson can repair the electronics in Meade telescopes. You only need to send him the boards with your detailed description of what you believe is burned out.

He can be reached by posting a message on the Yahoo LX200 and or LX90 Group forums.

Also Dr.Clay in Arkansas can repair the scope along with Meade (possible if they have new boards) -- Dr. Clay can be reached here:

Toshiba tv fuse blown


most electronic applications use what is known as a "slow blow" fuse and they are available fro electronic spares shops (JAYCAR and the like ) however if the fuse blows , you have a much bigger problem so take it to a repair shop and have the problem properly diagnosed

Tub lost power when turned back on have no power to key board.


It is possible that a in line system fuse may have blown?
Also check if main power supply has been lost, normally there are two disconnects. The Main one at the main power circuit panel, that is normally a 50 amp 2pole breaker; and there is normally (by code) a 2nd auxiliary remote disconnect. Which are also 50 amp. But you could have a smaller amperage style???
I have seen many of these be a "Fusible" pull out style disconnect. You could have blown one of the fuses? Even if one blew, you will have a completely dead spa. Check this and see if you may have one?. Note these are a special type of fuse, they will be "Time Delayed or Slow Blow" system fuses. And they are about 1" in diameter and about 4" long. They can be either mounted on the pull out handle itself or inside the box pushed into their terminal clamps.
It could like one of these, click the links provided below...

or this one, (Fusible and Non-fusible look alike)...

The fuses behind the cover will look something like this...

When pressing the power button to switch on, nothing happens


You have not given us much info to work on Errol, such as what make/model you're having the problem with? Also, what country are you in?
Going back to basics, you need to check two things first.
1. does your wall-socket outlet work for other things?
2. Assuming yes to the above, the appliance fuse is of course in your plug (unless your country has different arrangements to the UK). The appliance itself will have no other 'user replaceable' fuses that are accessible.
If 1 & 2 are unsuccessful at resolving your issue, then you've likely suffered a control panel failure in your appliance (an expensive repair unless you have insurance).
Good luck

Fuse blown in Emerson TV


If fuse should blow up, there must be some reason for that. Either a shorted component at its main power supply section circuit, or an over-voltage occurred at the household electric power. Before replacing the fuse, you must make sure the reason for the failure to present fuse, otherwise, so many other faults too might occur. It will be best to contact any service technician in this case.
Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

My 39 inch tv fuse blown constantly


Either a short or incorrect fuse being used--fuses have become specialized beyond amperage and voltage ratings--a lot are special fuses and or either a slow blow or even a thermal type fuse.

If not a fuse issue, look for a short in the power supply or wherever that fuse is located.

My GE1340 built-in microwave stopped working completely. It is just dead and does not respond when you push buttons. No power. Checked circuit breakers - all are fine. Any ideas? Is it kaput?


There is usually a 125V, 20 AMP line fuse inside most microwave ovens. It will be mounted at the point where the power cord enters the back of the unit, in line with the power cord, or on a small circuit card called a line filter. Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacturer and model. Parts are available at any of the following websites: searspartsdirect.com pcappliancerepair.com appliancepartspros.com repairclinic.com The first three sites include illustrated parts listings that can help you locate and properly identify any parts you may need. The microwave oven may also equipped with various thermostats that (if blown) can cause similar symptoms to that of a blown line fuse. So, if the line fuse is NOT blown, you may want to check all the thermostats to see if they are still good. You will need to remove each one and measure across the terminals with a multimeter. A good reading is 0 ohms. NOTE: The thermostats typically will trip if the oven cavity has been overheated. Cooking items that are high heat producers such as popcorn or baked potatoes in rapid succession can often cause this problem. Allowing the oven cavity to cool a few minutes with the door open between cooking can prevent this from occurring.


If the line fuse is blown, you can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended.

If you have any questions, or need additional assistance troubleshooting, please post back with your MODEL NUMBER and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit. These ovens can blow a fuse by simply sitting idle. This can occur from any power fluctuations, brown outs, voltage spikes, etc. Or, it could be the symptom of a component that may have failed. If you find the internal fuse blown and replace it, only to have it blow again, you have a more significant problem than a simple blown fuse.

Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. I found this wiring diagram at pcappliancerepair.com based on the model number you listed this question under:

http://pcappliancerepair.com/model-display.php


This model has TWO potential causes. The line fuse or the Thermal Cut-Out (Thermostat) for the Magnetron. The line fuse is connected in line with the power cord inside the unit and is listed as part of item 26 under the "Cabinet-Base-Cavity" heading.

The Magnetron Thermostat is listed as item 6 (part number 56001028) under the same heading. If you managed to overheat the oven any time recently, you may want to check the thermostat to see if it is still good. It should read 0 ohms when measured out of the circuit across the terminals.

If the line fuse is blown, you can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended.

When i switch on my Bernina Artista 180 it blows


Almost-certainly due to the main switching transistor having blown, however this is not necessarily an easy fix ... very often when this happens it takes a number of other components with it ... I had one last week where no less than 10 other components had got fried (and I do mean fried beyond recognition, due to somebody having put a bigger fuse in - doh! - dont ever do this ... it's dangerous!). Best thing to do if you dont really know what you're doing is to get a complete exchange 'L'-print.

I have an old Philips Audio/Video Receiver model# FR60XXBK02 I was listening to my system and it just shutoff on me and when i went to turn it back on it wouldn't. everything else hooked up to the same...


You may has a blown fuse inside the receiver. Unplug it from the wall, open it up and look around the area the A/C plug goes into the board. There should be a glass fuse. Sometimes you can tell by looking closely at the fuse if it is blown. They have a very slim filament that goes from one end to the other. If it is broken or not connected or if it looks like it is burned anywhere in the glass area, it is blown. Look at the metal ens caps for a amperage rating and get another fuse of the same value at radio shack or anyplace that sells fuses. make sure the power cord is not plugged in when you do any of this or you will get shocked.

When you first go to turn on the unit, do it with the speakers disconnected. That way, if a speaker is the cause of the fuse blowing, you will at least see that the unit turns on.

If it does turn on, turn it back off and connect the speakers and try again. If it blows a fuse, you most likely have a shorted speaker causing the amp to draw to much current and blowing the fuse.

If you replace the fuse, and it blows again after turing the unit back on with speakers connected, you have much deeper problems that will require electronic troubleshooting to determain the exact cause. But it is normally the amplifier having a shorted channel. Sometimes a random part failure can cause this for no apparent reason.

You will then need to have it serviced at a service center.

I hope this was helpful, let me know if you need more help.
