Question about Compaq Presario CQ60-220US PC Laptop
Either of the parts can be faulty or in some rare cases both. In most of such cases (HP-Compaq) that I received for repair, it was Invertor. Inspect the Invertor for any apparant physical damages (burnt coil or circuit components etc). Inverter can be checked by disconnecting the present CCFL and connecting a fresh/ working CCFL (Backlight) before actually removing the CCFL as it is difficult and unnecessary to take it out if its not the fault.
So, my advice is that you check the LCD display for replacement of Inverter . I have found a general link about CCFL replacement. Click here for detailed and graphical DIY instructions about LCD disassembly.
Make sure you take proper precaution while working inside LCD, as the inverter generates a very high voltage.
IF YOU ARE NOT EXPERIENCED WITH WORKING INSIDE SUCH ELECTRONIC COMPONENTS, I SUGGEST THAT YOU SEEK PROFESSIONAL ASSISTANCE FROM AUTHORISED SERVICE/ REPAIR CENTER FOR REPLACEMENT OF CCFL OR INVERTER.
Hope it helps! Good Luck!
