Light flashes charger - Samsung PL120 Digital Camera

limited info generic answer something caused charger to fail need to check for short - battery failure - circuit failure

Question edited for clarity and correct spelling of the maker.

Here is the manual section on the LED Lighting sequence. Both Red and Green flashing is not there. Your charger has a model number on the bottom of it and you didn't supply that, so this may be the wrong charger!

On some chargers, when the light blinks rapidly, it means that the battery is bad. Try looking up charger information on-line.

Please try this:
1) Make sure camera is OFF.
2) Plug Charger into the wall (not into camera)
3) Last think plug charger into the camera

Hi Suzanne! Follow these steps to check that your charger and battery are working properly.

1. Unplug the charger for at least 30 seconds.
2. Plug the charger back in. The blue light on the charger should flash once.

If the blue light flashes once this is an indication that the charger is still functioning properly. If the blue light does not flash, the charger will need to be replaced. Follow this link to order a replacement charger. LiNX Battery Charger

3. Place the battery in the vacuum and turn it on for 30 seconds. (even if it does not turn on or powers off)
4. Turn the vacuum off.
5. Remove the battery and place it in the charger.

If the light on the charger is solid blue this is an indication that the battery has been reset. Allow 3-4 hours for the battery to fully charge. The blue light will start to blink slowly to indicate the battery is fully charged.

If the light on the charger is flashing blue or there is no light at all this can mean that your battery needs to be replaced. Follow the link to order a replacement battery. LiNX Lithium Ion Battery

Hope this helps!

A red light indicates the charger is charging the battery, an amber light means it has switched from fast rate charging to trickle to keep the battery topped off, and green would mean the battery is completely charged. But don't be fooled waiting for green, many times the charger will only be on green for a moment before changing to amber and keeping the battery topped off.

Flashing can be a sign of a problem on some chargers.

A rapid flashing red can on some chargers indicate a bad or shorted battery, or a bad battery contact in the charger itself. If in question, try a different battery on the charger or compare with another charger to determine if the blinking is normal.

Best regards.

Sometimes when a battery is too low it takes a while for it to initialize in a charger and begin to charge. Clean the battery contacts with a pencil eraser and put it back on the charger. Leave it on the charger despite the blinking light. Leave it on the charger for several hours and see if the flash stops and it becomes a constant light indicating normal charging. If this does not work, you may have a short in the battery or in the charger itself. Try another known good battery in the charger and see if you have the same problem. If so the charger has an issue.
Best regards.

Charger flashing red indicates the battery is still not full and is in the process of recharging.
Red light steady indicates your battery is fully charged and ready to operate with your Coolpix 5000.
When red light is off it indicates there is no battery inserted or the charger is not pluged in.

I really don't have any idea as to what you're talking about here other than a battery and maybe a charger. Seems as if you're saying that you have a 12 volt 1.5 amp automatic battery charger connected to a 12 volt, 8.5amph battery but the red light on your charger is blinking. The blinking red light indicates that the charger is not seeing a proper connection such as crossed polarity connection or simply a poor connection. You say that the battery voltage has dropped from 12.5 volts to 9.1 volts with the charger connected. If this is the case, the battery is badly discharged and the charger is not charging the battery for some reason. The charger may be bad but check the connections to make certain they are correct and good. If they are, I'd replace the charger.

Good luck
Steve
