I've been cruising around looking for an answer to my problem, but no one who posted has the same problem I do, therefore I'm not sure if the process is the same.
About 10 months ago, my laptop screen just up and went black. I could faintly see what i had been doing, and moved the mouse (with MUCH patience) to shut down my laptop. Back then, i kept trying to turn it on seeing how long it would last. I would start the PC it would start up with a pinkish red tint (very light, hardly noticable) and I would hear a high pitched noise coming from my laptop. I would then get into my desktop and everything would be fine. Randomly I would hear the noise again, and my screen would go dark. I have a docking station for the laptop, and just connected it to my PC parts and everything worked fine, no issues at all.
I stopped using it, as i was tired of not knowing when it would go out. The laptop is as follows:
Dell latitude D610
Using the windows XP OS.
Last week, I started it up because I wanted to use my photoshop again for work. The screen lasted a good 3 hours before shutting off again. Once again, it only goes dark, I can see if i look hard enough, and the computer responds to all my actions, it just goes dark.
I googled a few things, and saw that I can replace the blub in the screen manually, but when i took it to a few shops, they all told me the screen itself was bad, and that I would need to replace the whole thing for about 200$. I'm wondering which is right, my dad tried fixing my laptop once and broke my wireless chip, and one company i took it to said that the laptop was over heating and trying to connect which is why the screen is going black.
Just wondering, any help would be appreciated, i need to fix it asap.
