Hello all, i have a problem with my laptop screen, please forgive me but this is long. I tried to turn on my laptop one day and the screen was all black. I could hear it still on and heard the fan running but i saw nothing on the screen. So i did a google search and I tried unplugging the power cord for 3 minutes with the battery out and holding the power button for a minute then plugging back in the power cord with no battery and turning it on but I still get a dim screen. So I tried this again with the battery instead but no change. So I kept slamming the laptop shut then opening it and turning it on until finally it worked and the screen was bright like always since i use the brightest settings for my laptop anyway. Then I turned it off after a hour of usage since it was working again, came back 1 hour later and tried to turn it on but I got that black screen again. So I started to slam shut my laptop 10 times turning it on after each slam to see if it worked but the screen just brightens on starting up but immediately goes black after 3 seconds, i can't even get into the safe mode with networking, bios part or anything since i can't see it. So today I was in a different room with better lighting and I could see it wasn't black but instead dimmed really low since I could see all my programs and stuff. I just can't do anything with them since its so dimmed I can barely see it.So i tried to brighten the screen and saw that it wouldn't brighten up just stayed dimmed as i stated before i use the brightest setting for my screen anyway. So now i tried to turn on my screen and it did the whole brightening for 3 seconds then black thing. So i pulled back my screen cover and started poking at the inverter ( i really just poked it a few times and wiped it off) and turned on my laptop and it started to work a little better. So i got a dust cloth and wiped off the invert-er and hit it a few times, constantly pressed the fn+f8 key which is my CRT/LCD key and it worked again. I'm currently on my laptop now typing this out. So what i wanted to know was what was wrong with my laptop because i keep reading stuff about my monitor back lighting lamp going out or the inverter going out, but i doubt it since when i start it up there is always a bright screen not any dimmed screen but it goes completely black or dimmed after 3 seconds. Has anyone else experienced this problem and do you know what is wrong with it. I've had this laptop for a full year now and never has this happened. I am currently using windows xp also i don't know when this will go out again so i'm not turning off my computer. Also i have 3 green lights at the top of my screen for caps lock, scroll lock, and something( can't remember the name) the one that name i don't know is a solid green color it's not blinking on/off, flashing, or anything i read something on google that if the lights are flashing the it's a problem

Hi, your problem could be the inverter or the backlight in the screen. If you don't want to paid over 20$ to repair your laptop, plug it to an external monitor and your problem will be solved.

It's very simple actually. Like everything electrical, if you bang it or shake it and it starts to work, it means that there is a loose connection somewhere in the laptop involving your screen backlight. I'm afraid you would have to take it in for service to fix the problem because opening up a laptop and fixing it takes a lot of time and expertise. I could do it, but I'm doubtful that you could.

Okay, that was a little insulting to me but i will over look that last remark. I can't send you my laptop so i will try to fix it myself instead. I however don't know what to look fix the loose cord. So can you tell me what to unhook, where to find it, and what it should look like. Or can you tell me how much it may cost to fix this because i paid $110 for this laptop i refuse to pay over $20 for this to get repaired. Thank you.

P.S. The laptop shut off on its own last night so i turned it back on and i got the same start up 3 seconds this all black screen soi tried hitting it again but the light got dimmer when i did this on start up which it never did before so im going to stop hitting it for now. Tried turning it on now and the start up 3 second screen is bright again (Yay!! somewhat celebration but still goes to the black screen)
