Screen is black three lights 9 a lit - Dell Vostro 1710 Laptop

There may be screen damage and that entire part of your screen may just contain dead pixels.

Its possible one of two thing have occurred, you have maladjusted the G screen control on the high voltage screens and focus assembly. Turn down (counterclockwise) all three of the screen drivers. Adjust each until a light appears in the each lens, red green and blue. Go slow or lines will appear if set too high. If all three lamps stay lit after this adjustment the look at your screen with color level down to zero using your remote and the picture menu. Adjust the three color drives to get a good black and white balance appearing on the screen. Now adjust the color level from the picture menu back up to normal range.
If you still get green diagonal lines after this adjustment then I would suspect that the green lens has a heater to cathode short in the tube.

at this point, you should back up all your data and reinstall the operating system.

Try performing a cold reset. press and hold "6" while booting and counting RAM. Release when all 3 led's are lit. Use "3" and "9" and navigate to "Cold Reset". Press 6 to enter.

Its either going to be the inverter or the lcd going back and it can't keep the screen lit.

Also I've seen it where the capacitors on the power board go puffy and they need to be replaced.

It will be one of those three things.

ask them about light eng replacement.

possible lamp is burned out,look in your manual for info.

Sounds like the back light on the screen isn't working properly which will need to be replaced if this is the case. Check for a very dark image on the screen when it is booting up in a well lit room, if you can see the computer start up then it is the back light.
