check and make sure your video card is seated properly if it is my best guess without doing any testing is that your video graphic card is broken

PACKARD BELL EASYNOTE SJ51. NO INVERTER VOLTAGE. ALL LEDS OK, SOUND OK, BOOTS OK, SCREEN BLACK OR POSSIBLY DIM.


Simple test: get a flashlight, go with the laptop in a dark room and point the flash light at the screen. If you see the image then indeed the inverter isn't working. of you don't see it then the data cable between the motherboard and the screen has been damaged: replace it.
If the inverter is at fault you will need to open the screen cover and check if the inverter board receives power from the motherboard: if it does you need a new inverter board

If it doesn't then a complete testing of the motherboard will have to take place to find out why and if it can be fixed.

Screen is totally blank at startup. HDD light blinks for a little bit, but screen stays blank.


1. Test using an external monitor. If it works, then either the screen bulb or the inverter board might be defective.
2. Test the inverter. Easiest way to do it if you have a good screen with a good bulb. Connect the good screen to the inverter board & test it. If it lights up, then the inverter board is good. If it did not, then the inverter board is bad & needs to be replaced.
3. If the inverter board is good, then we are left with the possibility that the screen bulb is bad. To fix this, we will need to replace the LCD screen.

No light on screen of acer extensa 4620 4605 PC notebook


This is a problem I have experienced with my HP laptop as well. I found some info on this and was told that it was the inverter. I managed to fix this by finding the inverter and, unplugging both ends of it and plugging it back in. This fixed the problem and a week later its still working!

The inverter is usually located at the bottom of the screen. To access it you need to unscrew the screws around the screen. This will involve removing the plastic covers and simply unscrewing them.

Once you have removed the plastic cover from around the screen, you should see the inverter at the bottom. Re-seat the connectors, and see if this fixes it. If not, replace with inverter. The site below is an example of where you can buy one.
