The screen probably wasn't bad. It's most likely the inverter board. This is what powers the back light allowing you to see the screen.

Powered but not booting. No visual. HDD light not doing anything.


Remove the RAM and start, see if it beeps and/or shows something on the screen. Try with the external screen too.
Let me know how it goes
Cheers

Window doesn't come on


That question does not reference what exactly is going on. Please step through from plugging in power adapter to power from wall outlet and pressing the power button.

ie: 1) plug in power adapter (i see charging light)
2) pressing power (i see boot screen logo)
3) next screen (i see windows boot logo)
.... and so on...

Purchased Vistaquest FS-503 converter. Used two days. Screen doesn't light up and closing cover doesn't turn off the power (light continues showing through the slot for slide holder). Any easy...


take it back for exchange or a refund. A capacitor in the circuit is at fault not distributing the needed power to operate this camera

When i putu the power cable on, the led light blink once and goes off. the screen is black. no fan is moving or any sound.


You should try to start your computer without the battery installed. If that doesn't work, you should try another power supply. If that doesn't either do the trick, it could be the motherboard causing the trouble.

My screen doesn't work, it is sleeping. What can I do ? After I took a rest my screen dit nothing. Whatever I trie, it doesn.t light up.


Try restarting your computer, If it happens again, try to find a pattern in the problem. If you can't restart, hold down the power button for a few seconds to do a forced shutdown.
