SOURCE: I can not see anything but lines all over my laptop screen.

Video corruption. Try booting from a Linux Live-CD - if that fixes it then your OS was corrupted, reinstall it. If not try using an external monitor - if it's the same then the video chip (and the entire laptop with it) is dying. Non replaceable, buy a new laptop. If it works then the lcd panel (or the connections to it) are gone - take it to a shop, nothing you can fix.

What caused a black screen


I had the same problem. While rebooting the laptop the screen would be on for a few seconds after it finished rebooting then the display would go black. If you looked very carefully at the screen you could see the image was there but there was no light behind the screen to make the image visible.

I removed the black plastic display bezel cover that goes around the edge of the display screen to check out the lights and wiring. I found a small magnet that belongs inside the display bezel had fallen out of it's slot in the plastic bezel and was stuck to the inverter pcb (printed cicuit board). To fix this problem I secured the magnet into it's slot inside the display bezel with a bit of glue. After fixing the problem and putting the display bezel back together the laptop worked normally.

The magnet could possibly fall out if the laptop was closed and upside down then dropped on a hard surface. Mine did not feel very secure in the mounting slot which is why I secured it with glue.

This magnet is how the laptop knows the lid is closed. When the laptop is closed the magnet is moved closer to a magnetic switch on the inverter pcb and activates the switch. The laptop thinks it is closed and shuts off the lights behind the display screen. When the magnet fell out of it's slot and stuck to the inverter it activated the magnetic switch all the time whether the laptop was open or closed. This caused the laptop to think it was closed and shut off the lights behind the dispaly screen as soon as the reboot finished.

I have a Sony KDP-57WS550 TV that has a convergence problem. Based on the symptoms, I'm not sure whether to indict the convergence ICs. In the convergence mode, I can move the red (and blue) crosses,...


With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.
(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)

The colors are looking strange when the DVD plays. The colors look blue, neon greenish-yellow, but no reds. The colors are perfect when tv is on, but dvd screen, once movie begins, has strange colors. ...


Try placing the dvd-player as far as you can away from the TV. It may be creating EMI (electro-magnetic interference). Ensure that the wires from the DVD-to-TV are not positioned close to other electronic devices -try moving them.

You say the TV works fine on its own, so that is good; there is probably no big magnet or speaker near the TV.

If it is not anything external causing interference, then yes, your DVD player is probably malfunctioning. Try borrowing a friends..

Screen wires loose?


Sounds to me like its the cable going from the lcd to the motherboard. Probably needs to be reseated as long as its not broke from the fall.
