We will be concentrating on LCD Inverter and CCFL bulb.
Laptop with black screen problem is commonly caused by:
1. a defective backlight, which is the cold cathode fluorescent lamp(CCFL) bulb
2. defective laptop's inverter board
3. no video output going to the LCD Screen
It is not an easy job repairing laptops specially if we don't have parts that we can use to replace to the parts we are suspecting to be the culprit. So now, we... [ Continue reading... ]

This is a project for those who want to build their very own Automatic Battery Charger. This is a project made by one of the member of Elab Forum, duc_tech. But as a reminder, this circuit don't have a current limiter which means this charger is good to use only on a known good battery but not on a battery that have defects like having a short or open plates which will cause the diodes, switching Thyristor and transformer to heat easily....

Upon surfing the net, I have found this site: http://electroschematics.com displaying their projects on making a Transformerless Power Supply with a 12 volts output voltage and a current of 100mA. We usually see this kind of power supply on a China made model of rechargeable products like flashlights and mosquito killer. This circuit catches my attention because of its application in our work which needs a power supply and we can also use... [ Continue reading... ]
