Brief expert summary tied to the thread: the symptom reported by (laptop powers on, both built-in display and an attached monitor show nothing, but the internal panel gives a very brief flicker) and the hands-on troubleshooting by narrow the likely culprits to three areas: (A) memory/POST failure, (B) the video subsystem on the motherboard (GPU/logic), or (C) the display/backlight circuitry. The next steps should be a short, ordered set of non-destructive tests that isolate which of those it is.

Suggested diagnostic sequence (in order)

  • Check POST signs first: note fan/spinner activity, HDD LED, and any beep/LED blink patterns during power-up. Those patterns are diagnostic; record them against the service manual if available.
  • Remove power and battery, hold the power button ~30 seconds to discharge, then boot with AC only. Remove the hard drive and optical drive (so BIOS must show something). If the system shows BIOS or beeps with drives removed, the issue is software/drive-related; if still blank, continue.
  • Test memory: try one known-good RAM module at a time in the primary slot (many blank-screen faults are bad RAM or a bad slot).
  • External display check: connect an external monitor, power on, and cycle the video-output key (Fn+display key) during boot. Some laptops need that to route BIOS output. If the external shows BIOS but the internal stays dark, the laptop’s panel/backlight or its driver is at fault.
  • Image-without-backlight test: if a very faint image is suspected, use a bright flashlight at close range (in a dim room) to look for the desktop/BIOS text. A visible picture without backlight points to inverter/LED driver/backlight failure; no picture on either internal or external suggests motherboard/GPU failure.

Physical inspection and cautions

  • Look for swollen/burned components and smell; those are strong signs of board-level failure. If comfortable and trained, check the backlight inverter fuse for continuity, but do not probe live high-voltage lines.
  • Reflow/reballing of a failed GPU is an advanced, often temporary repair; logic-board replacement is usually the reliable fix but can exceed laptop value.

Practical closing guidance

  • Try the RAM and external-output checks first (low risk, no cost). If both fail, the problem is likely board-level and professional repair or replacement is the practical next step.

ok i might be able to help you as i fixed about litterally 50-75 laptops like this over christmas break...my say is its not your graphics card. And i am 99% sure of it. That being said your fix probably wont end up costing you anything either. if your willing do take your computer apart (make sure you remember how you did it so you dont end up with a spare parts pile) then take the entire thing apart and reseed all the components because it could be anything. This means everything. Also take the screen apart and you will find a back connectors there as well. Like i said seriosuly this sounds crazy but reseed everything because some components come ajar, and it will most likely fix your problem. Good luck :p

i took the laptop apart like you said and put it back together and i still get the same thing. I do notice thou that when i turn the laptop on i see the screen i guess you can call it flicker like as if its tried for a sec. what do you think this means.

Ok on the back of the computer's lcd there is a ribbon that attaches to the lcd and probably has tape over it....that is the back light that lets you see your screen. like if you hold your screen at an angle you can see something on the screen just super faint during boot up? if so try that connection...if it isnt working with reconnecting it then its probably not the lcd itself but the back light that gives the computer monotor its brightness...as far as i know tho, those are really costly
