Question about Dell Latitude C640 Notebook
After a while i get a dark hot spot in the lower left hand cornor. Do i need a new LCD or a inverter not sure what to do.
Well the inveter powers the lamps in the LCD itself. If the lamps come on ,you don't need a new inverter but more than likely just a new LCD! hope this was helpful regards, babb

It could be a power supply problem or an inverter board problem or something internal having to do with the backlighting of the unit. remove the inverter, and look at the back side and you will see a hot spot, now on the other side of that hot spot, re-solder the service mounted components and that should take care of your problem.
Please get back to us if you have further query else please accept the suggestion.
