First check the battery. Is it charged? Is it healthy or old and dead? If the battery is OK take the camera to a service facility; you cannot fix the insides of cameras, unless you are a trained camera technician.
# Potentiometers are available at electronics parts stores, physical or online. If there is one near you take the potentiometer to it and let them try to find a suitable replacement. If you intend to change the lamp to LED you should make sure that the LED lamp you use is dimmable. If not it will not function properly.
Remove the battery for a few minutes and try again. If this does not reset the operation, there is not much you can do by yourself, as the camera’s insides are very intricate and delicate stuff; take your camera to an authorized service facility.
Have a vehicle electrician (or authorized mechanic) check the electronic charge controller and relative wiring and connections. These should have been checked before you replaced all these parts… Measurements can locate and identify the trouble maker part.
In most cases yes. It depends on the age of your machine and on whether it is still supported by its manufacturer. Contact you local dealers and give them model and serial number and they’ll tell you whether replacement is available and at what price. Often this information can be found on web sites.
You may have removed the lint from the door filter but if there is a heavy lint concentration on the walls of air ducts (which inevitably happens after long times of usage) free air flow is hindered. If this is the case you need to remove appropriate machine covers, so you can reach deep into the air ducts and vacuum lint.
If you have the printer software (driver) load it on your computer. If not you can download it from the manufacturer’s web site. Some printers include the driver files in their memories, so they are automatically detected and loaded by the computer.
Possible causes: * The battery is dead. (1) There is no voltage output from the charger for a number of reasons (e.g. cable, fuse, or electronic component failure). (2) Failure of connection inside your laptop, so charging voltage does not reach battery. If you have a voltmeter check charger output. If there is no output check/repare or replace charger.
