compaq 700us screen problem

by gregdojcsak May 28, 2005 2:15PM PDT

Hey guys!
Thx for everyone who reads my problem.. I am just looking for ideas and some of you are really experienced hopefully, you guys can help me out. Anyway I got this laptop and the AC connector at the back was becoming loose. I didn't want to wait for a new power jack so I decided to solder the power the the motherboard. So I did, now I am not good at all and while I was testing the soldering I did touch some of the components of the motherboard around the power plug area and it did some sparkling. After I put all the components together. Suprisingly the laptop turned on except the screen. The screen is totally black. Sometimes if I look really close I can see the desktop, but it is soo dark that I can only see the start menu if I look really really closely. There is a svga plug in the back of the laptop so I decided to plug my svga monitor into it. And it works fine. I personally think its one of the components on the motherboard... because the screen was working fine 1 day ago. But I really care about anyones opinion. Please Just positive feedbacks. Everyone makes mistakes...

Lid switch

These are known for the lid switch sticking down or closed.. Right rear of the system board, Pop the plastic top reatiner off and pull the gold plated spring contact/rocker out with a pair of tweezers.. See if this helps..

hey thx a lot for the reply, I am not 100 percent sure what you talking about, but I will open my laptop and look around, Would this be on the back of the motherboard or just on the top?.. thx

Right rear

Directly under the push down pin on the power button panel.. All you need to take off is the power button bar and keyboard then you can get a pick into get at it and pull the top of it off. Just be sure you get the tin rocker out as it could short somthing out or open if its left inside..
