Son Viao no backlight.

Hello. I am new here and looking for assistance. I have a Sony VPCEE42FX and a cracked screen. Before I took the old screen out, it would light up. I have since tried 2 screens but neither would backlight. The last one i sent back, they tested and said was good. He told me that I may have popped a fuse for the backlight. I need to locate that fuse and replace? I have the back off, looked at the cable connector and cant find a fuse. Is it on the other side of the mobo? or where on these models?
Thanks so much.

 

Take a hi-res photo of both side of the board around the LCD connector and post here, I will probably let you know where the fuse is.

 

hi ngvuanh, i´m having exactly the same problem as eciessau.
Can u plz help me with the fuse location if i send you a picture of the mainboard.

 

same problem with my vgn-z4, ngvuanh, can you help me too? (plz)

 

Fuse is in center of yellow circle

 

Thanks! You're the best! I will try to replace it.

 

Yes, the one in red circle.

 

I bridged the fuse (it is very small) and now the backlight works again! Thanks

 

Hi Experts
I have a Sony TX2XP laptop, the screen cracked and I thought a simple replacement of the LCD screen would solve the problem so I bought one from Ebay and plugged it in ( without removing battery ). The backlight failed to come on so I tried plugging in the old cracked screen which although was cracked did have a working backlight, but this no longer worked

Could an expert please look at my attached images and tell me which fuse I need to bridge.


people with weak technical skill are discouraged from answering

 

Fuse is in red circle.

 

Thanks Ngvuanh

Nice simple response which worked!!

as a test I placed a piece of tinfoil covered with blutack and BINGO the backlight came on.
