My dc adapter in my g1x zoom is not working. could someone pls send me a picture of where to connect the + & - wires in the circuit board. thanks.

Some possibilities:

• Damaged on the DC-IN socket.
• Broken solder joints on the center pin of the DC IN socket (see figure: pin 1 on DC208B).
• Damaged (broken) in D2 or R54

.

Have you tried to reset the unit? You can do this by holding save button for few seconds while connecting your adaptor to g1x/g1xn. Then the indicator will blink, then push save button again,this will reset your unit into its factory settings

You need to replace the power resistor R54:

I have the same problem dude!

Is the unit old?? Is it stored in an environment that has temperature fluctuations?? It could be the terminals on the input of the unit have dry jointed. This is when the solder lifts away from the circuit board. I have had the same problem on my ZOOM MRS1608 recording desk. Resolder the connections on the input. The base plate will problably remove easy enough to get to the point where the adapter is soldered onto the circuit board.

Good luck

if you're using an adaptor other than the original zoom, make sure it's 300mA or more and try switching the polarity.

The first thing i would check is the ac adapter .Make sure you are getting the correct voltage from the adapter.If you know how to use a voltmeter or know someone that has a volt meter,check it with it unplugged from the guitar pedal,most of these have a voltage range from 9 to 12 volts dc.you could also take it to your local radio shack or local repair shop and they will be glad to check it for you for free.after you confirm the adapter and it is ok then the next thing you will check is the input jack assy on the pedal,input jack assy are soldered onto the board at the factory,these jacks ,no matter what it is are famous for cracked solder joints where the pins of the jack go into the board because of stress delivered to it during plug ins and plug outs.if you dont know how to use a sldering gun or dont want to you will have to take it it to your local repair shop-cost should be around 15.00, 20.00 tops,make sure that your guitar cables are good,check the 9volt battery inside the unit if it takes one,if its dead that could be your problem,if all above fails i would send it back to the factory or wherever you bought it.,good luck been playing for about 30 years myself,rock on

I have a ZOOM GX1XN and it doesn't like universal adapters much. Using one with the wrong voltage or polarity may permanently damage your pedal. Try to obtain a proper ZOOM AC adapter (part number AD-0006 or AD-16) if possible. These are dual voltage and will work equally well with both 220 and 110 volts. Failing that you need an adapter that will give a DC (direct current) output of 9 volts at 0.5amps - maximum 4.5 watts. The outer contact (sleeve) of the adapter needs to be positive (+ve) and the inside contact negative (-ve). Lots of universal adapters are the other way around with the sleeve being negative - but some have a multi-connector on the end with both positive and negative sleeves.
