Dell Inspiron N5110 8 Beeps

[raajkumar]

I have a problem with my Dell N5110. this worked with External monitor fine. But Led working backlight only not any display on the screen. i checked LCD_VDD and is shown Power 0V. I found U4901 is faulty on this MB. Thereafter i tested with a jumber to pin 3 with pin 4. Display worked fine. i shut down the notebook. But unfortunately this jumber wire has touched with PR4002 ( DCBat out 18V ) after shut down the notebook. Now i changed blown fuse on the led screen and this notebook is giving 8 beep sounds ( Says No display attached. I try with the external also but same ). any one having idea ?
