Blank screen I have a dell inspiron 1501 when i switch it on i can see that the power is getting through ok but all i am getting is a blank screen if i switch it on and off around 30 times it will eventually respond and start up Its 3yrs old and has only had light useage

This sounds like a loose wire on the backlight on the monitor.
If it were my computer, I would disassemble the screen and check the connections. You can find directions on Dell's site by going to support.dell.com and entering your service tag to get the downloads. You'll find the service manual there.

Hi there !

Blue screen means that your hard disk drive is damaged and cannot be repair or reformat. But still to repair or run windows operating installation on your CDROM and maybe it is repairable. Other you need to replace your hard disk drive to work again your computer.

Good Luck.

Connect an external monitor to your laptop. If ok, then it means that LCD is faulty, on the other hand, if the issue persist, removed abd re-seat the memory module, if you have a good one do the same. If the same thing happens, it can either be the video or motherboard or it can also be the memory module.

Please let me know if the information has been helpful. Thank you and regards.

make bios recovery cd o rfloppy from dell official site

After the dell bios boot screen you should get a blank screen with a blue bar at the top saying www.dell.com when you get to that screen you need to press Ctrl+F11 and you should start the recovery partition

#1 Tighten the screws for the Display Hinges (The LCD grounds through the hinges)

#2 reseat the display connector to MB

#3 replace display

this sounds like a loose conection to the lcd inverter or the lcd cable to the motherboard. it can be repaired. how are you at taking things apart?

your os is corrupt so repair the operating system or reload it

Try changing the memory stick, if still doesnt work, it means the invertor of the screen is gone.
