Hi Veenadevi,
Use Seperate Switching circuit with MOSFET, and port pin to control, and u can also control brightness of Backlight by using one timer. Regards PADMANABHAM Hynetic Electronics Pvt. Ltd. BANGALORE, INDIA. |

| Check my changes in connections | 01/01/70 00:00 | |
| In some models.. | 01/01/70 00:00 | |
| Voltage level at the backlight pins. | 01/01/70 00:00 | |
| Is cathode short to the ground pin? | 01/01/70 00:00 | |
| cathode is at 0V | 01/01/70 00:00 | |
| Did you check for short between | 01/01/70 00:00 | |
