Having problems with your HP Compaq Presario CQ60-249US Notebook ?

My son spilled coke on my presario cq60. So i took it apart and cleaned what i could, it seems to work fine but the screen is very dark! You can just about see the computer loading on the screen but it is so dark. I dont know if i've missed something?


Answers :

Only other cleaning suggestions would be with Simple Green or isopropyl alcohol and rinse thoroughly.

Connect an external monitor to see if the laptop display is destroyed or the video card in the laptop is faulty.

Hope this helps.
That means that the inverter board is not working. The laptop will still work normally if connected to an external monitor.

The inverter board is an high voltage board that supplies power to the backlight lamp.

The inverter board is located at the base of display, and is connected on one side to the motherboard, right underneath the keyboard, and on the other side to the backlight lamp.

Check the connector to the motherboard. If the connector is OK, and there is DC volts in there, then the inverter board must be replaced, as it had been damaged by the liquid.

If you DIY remember that the inverter is an high voltage board, remove battery and unplug ac adapter before working on the laptop, do not touch capacitors contacts as they can release potentially dangerous discharge.
