I inherited an HP f2105 21" monitor from a neighbor and I want to try and fix it just for the EDUCATION. The problem is that when it is turned on the screen refreshes very slow and it has white streaks top to bottom. When I replaced it with a new one for my neighbor everything worked great and I've also tried it on a known good system so I know it's not computer or video CARD related. I get no hisses or screeches when it is turned on and left for over an hour. Also the mouse pointer leaves a huge white trail when you move it across the screen. I can't find ANYTHING on the net about this. Can someone direct me in the right direction? Thanks in advance for the help..If this problem continues on every computer you've tried it on, it is most likely a problem with the monitor itself.

What type of monitor is it? (LCD or CRT)Hewlett Packard f2105 LCD monitor. Yes, it's a problem with the monitor for sure. I'm trying to figure out if its the logic board or possibly the LCD itself. I probably won't be able to find parts very reasonable anywhere but I'd like to know why it's doing this. I've never seen a monitor do this before and it's only about 4 years old.Sometimes monitors break.

Something you can try. Look at the cable connecting the monitor to the computer. Can you find any bent pins or anything?Yea, I already checked the cables, used different cables and different machines and all the same. Your correct. The monitor is broken, but I just wanted to try and figure out exactly what was wrong. I think what has happened is a de-lamination or possibly a break somewhere in the polarizer layer in the LCD itself. From everything I've read this seems to be the most probable explanation. Obviously I'm not going to repair it, but it was fun taking it APPART to analyze. Thanks for your help. I think I'm going to give up on it at this point.Heh, you've managed to get inside your monitor?
I'm still having trouble opening up the one sitting on my shelf. , Yea, HP and Dell monitors are pretty easy to get open. Once you get the stand off (six SCREWS) the back cover pops off pretty easy. You just need to start it with a small screw driver, pushing in as you go around. Once the back is off it's just a matter of unscrewing "a lot" of philips screws and everything comes apart. The logic board, internal speakers, (if you have them), etc., all come out. The problem is that nobody wants to sell you the parts unless you know exactly what PN it is and HP, Dell, Compaq etc don't want to let you know unless your one off there "Certified" repair shops. The repair shops don't want to sell you parts. They'd rather you send them your monitor so they can charge you to fix it. Even if you get it apart and figure out what the problem is it's almost certain no one will work with you so you end up having to buy a new one any way. Yep. They're all after your money. ..it's funny how all these big box stationary stores are starting to offer computer repair. They get you to bring your box or laptop into the store and then try to tell you that it would be cheaper just to buy a new system. I don't think (apologies to anyone that works at one of these places), anyone there really would be able to fix something, but like you say ..they're all just in it for the money". Funny, though, I wish I could get some of that money, but I have a conscience. If you happen to get zapped by that opened monitor you'll never open another one...Quote from: patio on September 25, 2008, 05:14:04 PM
