MOBILE SOFTWARE WORLD: NOKIA 1650 HANDSET MAXIMUM REPAIR SOLUTION

by PAWAN SHARMA

Nokia 1650 handset is a handset came well after a long period of Nokia 1100, 1110, 1600. Its one of my favorite cheap and best phone with FM radio also beautiful colors. This unit also fits very well for the ladies too. His body cream with mix of red glass is its most beautiful. Although repair is also cheap, as the LCD and other spare parts. If by chance this is all a little damaged by reason of water or other liquid, its most sensitive parts of his jeck display, LEDs and pricing side, and the problem of tone. So first we would discuss the problem if you've driven it.It has two LEDs on the underside of the keyboard and white emitting LEDs of the rest are in the LCD itself. Firstly, we need to verify the LCD display, modify, if not always its light, then we must check his first tracks. It has four main tracks of two LEDs, Title I of IE first LEDon the left side, it has a positive supply in it that comes directly from the ic light by some small capacitors, multimeter check that this route should not be opened, the two other pieces of the first rib and the right second pipe leads to the left are met, this control also with a multimeter, then the last track of the second part leads right leads to the second pin on the right upper side of the display connector. And even after that if the light does not come, then it just changes the coil near ic light, or can also change the light ic.The other major fault is usually the pricing is, If the handset are the charge, then first check the fuse capacitor, and whether to connect the charger it says not charging, then the shortcut is just remove the little black double right side of the resistance CI EMU, it will definitely solve the problem, verify that the drag must be from the mid-pin battery connector, the resistance, we must eliminate it below.

Elektronika.ba - Nokia 1100 LCD with PIC microcontroller

Sometimes it is necessary to add an LCD display to our microcontroller project. We usually decide between character display such as 2x16 with HD4470 IC or other graphic displays.

Here we can see a driver for a graphic LCD display from Nokia 1100 phone which is good or even better solution than previously mentioned ones, especially because these displays are very very cheap. Driver IC on this LCD panel is PCF8814 which even though has I2C protocol support - doesn't use it. Instead it uses simple bit-banging mechanism for communication. Microcontroller that was used in this project is PIC18F1320 and source code is written in C and it can be ported to any other PIC microcontroller.
