ASUS A53S screen problem

[MLR]

Hello, this is my first time posting here and I'm not sure if I'm even doing it in the right place.

Recently I have had to have my DC jack replaced since it wasn't charging unless pressure was applied to the adapter plug. The notebook was still under warranty but since I'm in med school outside the US I was unable to send it in for repairs. The IT department at the school ordered a new DC jack and fixed it for me, but now the notebook screen is not working.

The screen will turn on, display the ASUS logo like it normally does, but then it will immediately fade to a blank screen. I don't think it's a backlight issue because he did the flashlight test. If I plug an external monitor in that works perfectly fine. The IT guy who worked on my notebook seems to think its an issue with the cable connecting the screen to the mobo, but if that was the case wouldn't there be no startup image at all? Also, when he was removing the old DC jack he clipped the connectors and used a soldering iron to heat up the old soldering, which he then proceeded to blow it away with compressed air, with small flecks of it landing on the mobo. Would that cause some problems?

I'm tearing my hair out right now, the loaner notebook given to me to study with in the meantime is a 6 year old Dell that struggles to change slides in Powerpoint.

Thanks for your time,
Mike

hi MLR i believe YOUR latop has 2 graphics cards installed can you enter bios

you can enter bios by pressing pressing f2

if you can enter bios you maybe able to see if there is a setting to use the Nvidia card instead of the intel.

if you can enter bios thats a good sign that your screen works.

Hi K9,

I recently discovered that there is an image, although it is extremely dim, to the point that I didn't even notice it until I had taken it into sunlight.

I asked the IT guy if it was a possible backlight issue but he said that my laptop used a LED and that wasn't the problem.

I'll try going into BIOS and doing that the next time I can go take a look at my computer again, but are you sure that's going to help? I think through settings I had it boot up using the Nvidia card each time.

Thanks,
Mike

LED backlights fail far less often but still can fail, if there is an image on your display but no backlight it's pretty obviously the problem. If your DC jack went out there is a possibility it's something in the power circuit that is damaged instead, but it would be hard to tell without swapping in a working LCD to test. If it never had this problem before the repair, the tech may have damaged something while swapping out the DC jack.
