I would it could be something as simple as an open fuse. Generally they cost around 75.00 depending on the charger.

I have a garman Nubia 1490. Works OK but will not charge battery when plug into car charger. Have used charger from unit supplied.

Do other devices work from your cigarette lighter? If so, check to see if the red light is illuminated on the charger. If the light is not on, the fuse in it is either bad or the charger is defective. It is not economically worth while to have the charger fixed if it is bad. If your GPS does not use a traffic receiver that is embedded in the charging cable, then any cigarette lighter charger with the right plug for your GPS will work. Otherwise, buy either an OEM or after market replacement.

It seems the problem with display as well as to the charging unit. Display problem can be repaired only br replacing the display. And for your set, its not worth to get the display replaced. You can get the handset to your near service man to check whether the power charging unit works well.

Thank you

The wall charger (UA 1803b) is hot and discolored. Is this a safety hazard? Thank you

If in doubt take it to a service centre and have it checked out. Some of these wall chargers are known to be copies that are fakes and therefore dangerous. Most chargers will of course get hot, but if you have only had it for a short time it should not be discoloured. If you have had for over five years then over time it might change colour.

How can I make my tablet charge when it doesn't charge with its charger

I don't know what connectors you have on your tablet, but often there is a micro USB socket for connecting a lead from there to a standard USB socket on a computer. Some devices can also charge through this connection, so this is worth a try.
You may also try replacing the charger with a new one, in case yours has become faulty (you could check for a voltage at the plug for the tablet when the charger is plugged in by using a suitable multimeter on the right setting. Absence of voltage here would confirm a faulty charger.)
Otherwise, if the charger is OK and all the connections are firm and good, it may be necessary to replace the battery as rechargeable batteries do have a finite life.
Hope this is helpful, if so would you please register that with Fixya

Bosch charger not charging

Its sounds simple but always worth a try, clean all the contacts on the charger, one will read the condition of the battery, If this is dirty, it may not be giving a strong enough signal to the charger and as such it will interpret the battery as faulty.

Powa Force drill charger is dead

Powaforce battery charger.

  1. Measure the dc output (with multimeter) on female plug. Should read ±16 – 20V DC. If no voltage here open charger and measure 220v AC on input wire before transformer. No voltage faulty input cable or 3pin plug. If ok check for dc voltage after transformer. If transformer faulty (not worth repairing) replace with same dc volts and amp (important)output. Check now output cable.
  2. If voltage is on cable but base does not light up, probable faulty capacitor. If light is on but does not charge, probable rectifier that gives too little amps.
  3. Any good tv repair technician can help you. My tv tech already fix about 9 of my torch and drill chargers. Parts usually about R5 – R10.

My charger is not working anymore. and i cant find one that works

If the charger works on another machine, then your laptop has a faulty mainboard.

if the charger does not work on another computer then you need a new charger. Take the brand and model etc details from the bottom of the charger / power adapter a find a replacement either locally or on for example.

if the new charger works on another machine but not on your computer, then your computer is faulty. Most likely not worth the replacement of a mainboard, I would buy a new laptop if you are outside of warranty.

you should take the laptop to a local professional to get a diagnosis and a repair estimate, as well as get your important files off from the hard drive of the laptop if needed.

Willnot turn on

Do you know if the charge light blinks when it charges or like mine it stays on untill charged then goes out, if it is blinking when it normally stays on during charging then it could indicate a fault ( usually with the ccd ) and could prove to be a costly repair if not under warranty, maybe worth getting checked out.



P.S. it could also indicate you have a faulty battery or ac adapter

Not working

Hi , Its likely you have a faulty charger putting too much voltage out , or , your car cigarette charger socket is dirty or similar causing intermittent supply and resulting in voltage spikes going through the charger and into the TomTom .... or ... spikes caused when starting your car whilst the charger is plugged in. The tomtoms are very sensitive to any overvoltage and it blows 2 IC's inside the TomTom. The car chargers are also known to put out overvoltage when they go faulty , it's quite common. Some car alternators dont regulate their voltage very well at the point of starting the engine so it's probably worth having this checked by an auto electrician. Cranking the engine cna also cause the starter motor to act like a generator just at the point where the engine fires and this then results in a voltage comming back out of the starter motor and into the cars wiring. Your TomTom charger should cope with this but it is possible that any spikes manage to get past the charger and into the tomtom. if you have had one TomTom blow using any particualr charger unit , then don't risk using that charger on a different TomTom uless you have that charger checked for correct voltage.
Good luck.

For the guest comment .............. The Blue Tooth will not have caused the problem you are reporting , thats just a coincidence. The problems of having buttons highlight themselves and the touch screen not working properly is a fault with the membrain on the tomtom screen . Could be a fault on the membrain or just dust and dirt particles trapped under and around edge of the screen bezel ( plastic screen surround ). Try clipping out the bezel and see if theres any dirt around edges of screen . If there is , be careful how you clean that dirt / dust out. ... Good luck
