DELL Inspiron 9100 LCD not working after replacing inverter

by salilsurendran May 3, 2010 4:51AM PDT

Hello Friends,
My DELL inspiron 9100 laptop screen went dim and I replaced the inverted with a inverter that i got from eBay. The dealer said it was for the dell inspiron 9100 but it was not from DELL but from a chinese manufacturer. It worked initially then the monitor started flickering and completely fizzled out. Now when I switch on my laptop my screen is very dim just like the way it was before I changed the inverter. I am not thinking of replacing the backlight but I am puzzled as to why on changing the inverter it worked for a few days. Maybe the dealer shipped me a wrong inverter and the inverter fizzled out? How do i make sure that the inverter is the right part and the backlight is the problem?

Now change both parts.

It's rare but can happen that the inverter and the CCFL tubes need changing. That is, if the CCFL tube is drawing a bit too much then the inverter can have a very short life span.
