My PC laptop monitor show yellow lines all over the monitor dnt know whats the real problem. I connect external camera its not working. It show troubleshooting and it says a mass storage controller is not installed. The original OS of my laptop is Vista but since it has no english version here in Japan we change it to windows XP 4 years after problem occured it says a certain driver is not working someone fix it and installed Windows 7 but the monitor shows yellow lines. Just want to know whats the real problem. Thanks

If you have an external monitor or LCD monitor, try connecting it to the laptop and then turn the laptop on - if external video shows up normally then most likely you have a bad screen; if both internal and external video shows pretty much the same white lines / white outs then the system (systemboard) is most likely bad.

Try connecting an external monitor to the 15 pin VGA plug located on the right side. You may have to initiate the external monitor by holding down the Function left of the Space bar and depressing the associated key, (it should have a little picture of a monitor).
If the display is fine on the external monitor then you have a bad LCD display. If you still get the yellow line on the external monitor your motherboard (system board) needs to be replaced.

610, the post above contradicts, laptop and disktop WHY?
no service tag presented. by you... (p/n of LT)
no need to post a store, we are in USA< not there. so
why not get the PC repaired in a real PC repair shop.
asking how to fix a pc with no full symptoms is hard
we are not HP here, we are fixya chat boxes,
so why ask here, and not real HP?
on the below page, see bottom left of page
see "contact HP" bingo?

the PC beeps what is the beep code.
does the screen ever show any text ever.
try the external VGA jack on LT to an external monitor.

does the monitors menu button show OSD screens?
I know that most post here show checking ram first
its a wild silly guess that.
the fact is it can be many things wrong.
so step one
1: what beep code is it, count them , it repeats so count them.
2: is there text or anything ever on the monitor, ??????????
3: does BIOS screens work, power on hammer F10 key?

2009 PC can have the solder ball proplems.
same with CCFL tubes dead.
Hdd failure
and for sure the small coin cell battery dead. this old.

see the black screens of ***** here, NO TEXT EVER on screen.!

Such occurrence can be due a to defective LCD (inverter, flex cable or the LCD itself). On the other hand it can be cause by a faulty video graphic card. Try connecting an external monitor and let me know of the outcome. Thank you and regards.

Press "Fn+F7" once, wait a few seconds, and press it again, to "cycle" through all the possibilities (LCD-only, VGA-only, both).

Try the monitor with some other computer (desktop or laptop) to see if the monitor works at all.

Restart your computer -- does the initial "splash" screen (showing CPU speed and RAM-test) show? Does the "Windows" screen (with the crawling worm) show on the external monitor?

Try this: see if you can find an external monitor, use a VGA cable to hook to monitor...tell me if the lines are still showing on the external monitor...
let me know.

Did you go to the display properties screen and check the settings of the second monitor connection. You must turn it on, and have it set to a low enough resolution for the monitor to work. If it shows the second monitor, Click Identify and it will put a number on the laptop screen. Which ever number doesn't show up is the external monitor. Select it and set the resolution down by grabbing the scroll bar and drag it to the left. Start at 800x600 or so and apply changes. If the monitor doesn't come on, check to see if the monitor is on.

Reseat the video cable connection under the keyboard, and see if the lines go away. If not, connect an external monitor, see if the lines show there. If the lines do not appear on the external monitor, then replace the LCD. If they do appear on the external monitor, replace the motherboard

the LCD screen is damaged.

hope this helps
