white screen problem on boot

I own an apple macbook air model number a1237 that has nothing but a blank white screen on boot after the startup sound. I have tried two different screens and lvds cables. it works great on an external monitor thought. any help would be greatly appreciated.

Thanks,

Cody

Hook it up to an external monitor to check the GPU and logic board.

The LVDS is causing the issue and needs to be replaced by a professional certified Apple Technician with appropriate device.

Update

1- The connector between the logic-board and the CABLE that comes from display is loose.

2- Other possibilities?

I had this same issue. White screen, chime, responded to light sensor. Hooked to external monitor, would get video there. But I could only get a white screen on the internal monitor. I swapped the logic board with a known good logic board and this fixed the issue. So I'm going to say it's a logic board issue, strange as it is, or a logic board to LVDS connector issue (all I did was remove this, the HDD connector, data/usb connector, airport card connector, magsafe port, iSight connector(?), and top case connector, to swap the logic board). I had a !@#$ of a time finding any info, so I hope this helps some people out there. I'm going to investigate and see if I can find any further answer to this.

yassarali26, this is a 4 year old question that does not get visited often. You need to give us way more information. what happened? what have you tried? What exact model is your computer?
