Re: lcd monitor streaking

The solution may be one of several things. here are my ideas in increasing severity.

1) Bad connection. Fix: tear apart the screen and check the video connection. It looks just like that when you don't have a good connection with the sync signals from the motherboard

2) Bad screen. Check video feed to external monitor. Shut down laptop. Plug in an external monitor. Start it up and the external monitor should show a good picture if the problem is a connection or a bad screen. If it's a bad screen, you will need to replace it (easy to do at home for 1/3 the cost of some outside source). Go to ifixit or instructables or repair4laptop to get ideas and walkthroughs. So, good feed to external monitor and no bad connections=bad screen... maybe.

3) bad video card. Replace motherboard = $$$. this is more difficult to do at home. If the external monitor shows the same streaky picture, you're pretty much guaranteed that you will have to replace the motherboard.

try pushing on various parts of the computer to see about bad connections, usually two thirds to three quarters of the way up the back of the screen is the connection and somewhere under the keyboard is the video card. don't press too hard, but see if anything's different when you try it. Good luck.

Re: lcd monitor streaking

I just had this problem on my Dell lcd monitor. Turns out it was just a loose cable connection to the back of the monitor itself.

Horizontal lines that look like streaks or smears, you need consider:
1) video card memory error cause it if the display memory on the video card
2) check RAM (clean pins and slot pin)
3) monitor power on without cable to see the menu display, it is ok if no streak, need to clean monitor cable plug.

H21 LCD Monitor -No display

With that many boards, it probably has a separate ballast (inverter) to run the lamps. In the power supply section, I would look for bulging electrolytics and bad connections. In the ballast I would suspect a shorted output transistor, a bad output transformer, a bulging capacitor or bad connections.

Monitor blackening out and sudenly shuting down...

Hello! Sorry to hear of the Tennis Ball Masacre. I believe your problem to be twofold in nature. First the glass in side of the LCD screen is very fragile and the tennis ball most likely ruptured it. the streaks are most likle the liquid crystal solution leaking out. the dark streaks represent the absence of the fluid. Secondly, the monitor shut down appears to be from the back light / inverter circuitry. Sounds like it may be time for a new display. $40 to $60 for the inverter board and $80 or more for a new display screen, you may as well go the couple of extra dollars and get a new monitor. Hope this puts it in perspective for you. Sorry it is so bleak!
