How to make your Remote Control Last Long?

Remote controls are now a days used much.Most of the electric devices now comes with remote control.Also failing of remote control rate is getting increased.
Most of the remote control faults are due to failure/ leakage of battery in the deivce. It is important that the cells taht you install must be checked in a time period so that you could find out before the electrolitics leak and damage them. for his keep a date tab on the reverse side as a reminder, replacing them maybe in a period of three months. however if you are keeping away many such due to low use, please try to take off the batteries and let them idle. If however you ahve encountered such an issue, immediately open the remote, use a good cleaner to wash off, dry the PCB using a good hair dryer , then assemly them after cleaning and oiling the contacts from rust accumulation.
You must do this remedial prevention for devices that hold a battery but kept without any use.
This basic details will help.

How to repair a Remote Control?

Remote control has long life,in most cases.Its use is very simple.Mostly its battery gets over and you have to replace the battery and it starts working.But sometimes this remotes stop working and you buy new remotes.New remotes are not very costly.But some times the problem is minor.Before you throw away your old remote have a try with these tips: First of all remove the panel by using a sharp knife on the sides, come have screws inside the battery chamber.Once remvoed you can find the main board on which is the circuit and the carbon pads. Solder the IC the crystal, the IR LED, the driver out transistor.
make sure the battery voltage goes to the IC and there is no track loss/break.If battery had leaked into make sure to clean well with petrol and insulate after soldering with varnish.
With the battery connected check the voltage on the IC, press a pad and check for the output at IR led.
Now use a IR detector with a multimeter( in Ohms range) to see the voltage change when the remote is pressed.Now try this on or change the crystal or IC, to get your remote working again.
This details will help.
