Basically the inverter board is the little thing at the bottom of the display that feels like it will snap off if you aren't really careful around it.
This isn't the exact right part, but it will give you some idea about what the inverter board looks like.
And I'm a bit skeptical about the claim of the ebay seller, and I say that as a Dell certified tech, but inverter boards are generally pretty cheap, and it shouldn't be too difficult to swap inverter boards compared to swapping displays on a laptop. You also neglected to mention why you bought a new display for your laptop.
But their rather poor english skills aside, they're basically saying to take the inverter board from your old display, put it on the new display, and see if that works. Seems more likely to me you got a DOA display, but it should take maybe 5-10 minutes to try the inverter swap and see if it does anything.
Also, having done a few display replacements in my time, did you ensure that the ribbon cable on the back of the display is in properly? And there's usually a connection that goes to the inverter board. Is that connected firmly?
so i got a new lcd screen for my dell inspiron 1720 laptop. Upon, installing the new lcd screen didnt work. It just flashed white then went back to black, but I could see the backlight on with no image. I was then told by the seller [from ebay] that the new inverter card may not be compatible with my system. He then explained how to fix it, but I couldn't understand what he was talking about.
btw here is the transcript:
"It looks the NEW inverter card may not be compatible with your DELL system. The LCD should be ok. Could you swap your OLD inverter back to the NEW LCD screen.
The inverter card at the bottom of your old screen does NOT need to be attached to the NEW screen. DELL makes some of your model brand NEW like this. DELL leaves the inverter card inside screen case. It does NOT attached to the bottom of LCD panel.
Once you swap the inverter card to the NEW screen and connect the LCD cable, you are ready to use. We have sold at least 100 such screens for your laptop model. No problem so far. "
can someone lead me to the right direction? just confused and frustrated.
thank you for your time and consideration,
