Having problems with your PC Laptops ?

The screen on my Advent 7096 has gone nearly black, you can just make out the display on the screen. Would this be a backlight issue or the inverter board? Regards - Chris

Hi,
The problem is the inverter cable or the inverter itself.
If you have any warranty left on the laptop then i recommend you take advantage of that and send it in for repair, or you can deal with this 2 ways.
Fix the problem yourself.
Remove the screen bezel (plastic screen surround), this will\015\012reveal the whole screen. At the bottom of the screen you will see an\015\012elongated piece of circuit board with wires coming from either end\015\012covered by frosted plastic.
That is the inverter, check the connections on the inverter and power the laptop up to check the display, to remove it\015\012gently pull the plugs from each end and remove the screw from the\015\012middle and pull the board away.
Look at the inverter for a copper coil, if you\015\012re-solder the solder points around the coil you may find it works again\015\012as components that suffer from extreme heat the solder joints dry\015\012causing bad connections, re-floating the solder solves the problem in\015\01290% of cases.

Take the laptop for repair.
In\015\012this case all you have to do is source a reputable PC repair store and\015\012take it in for them to fix. (it should be fairly inexpensive).



Good luck.
Sounds like the backlight is failing. The inverter converts the video image for processing and the backlight lights up the LCD. An LCD does not have the ability to light itself therefore needs a long thin bulb underneath the panels to illuminate them.
