Hi, if you connect an external monitor to your laptop, you see everything on the external monitor?

 

[Akhilesh_5]

yes it works

 

[jarotech]

The problem could be the L4 coil who is open, it can't give the power for the backlight.

 

[Akhilesh_5]

can you give me the schematics of the coil please?? its very urgent

 

[jarotech]

Find the coil L4 near the pins 1,2,3 of the LCD connector and check the coil for continuity.

 

[Akhilesh_5]

okay

 

[Akhilesh_5]

can you send me a photo i cant find it?

 

[jarotech]

Sorry, but I don't have the motherboard, you can instead measure the pins 1,2,3 of the LCD connector on the motherboard to see if you have a voltage.

 

[Akhilesh_5]

if i send you a photo?
can you tell me exactly where it is?

 

[jarotech]

Maybe, take two pictures, around the LCD connector on both sides of the motherboard and put them in your response.

 

[jarotech]

L4 is just beside the pin 1 of the LCD connector.

 

[Akhilesh_5]

it is not working

 

[jarotech]

What voltage do you have on pin 1 at the LCD connector?

 

[Akhilesh_5]

do you have an email or skype id so that i can send you the photo

do you have an email or skype id so that i can send you the photo

I reply only on this site for everyone to see the answer, never in personal mail. I don't need your photos, I told you the L4 coil is near the pin 1 at the LCD connector. I also asked you if you have a voltage on the pin 1. I provide you with a picture where is located the coil L4 on the motherboard.

 

[Akhilesh_5]

voltage doesnt come on pin 1 ?

what should i do now?

 

[jarotech]

Measure the voltage on both sides of the L4 coil, if you have a voltage on one side of the coil, the coil is open, need to be replaced.

 

[Akhilesh_5]

i dont get any voltage on any sides of the l4 coil
