LCD replacement
Ciao,
my Dell Latitude CpiA has some annoying flickering on the screen after some usage. The problem is related to the LCD/cable, because it disappears if I plug in an external monitor.
I was looking for a LCD replacement.
The issue is that there are a lot of different LCD brands used for this model and I guess they are not compatible one to the other.
These are my questions:
-I'm not sure about the exact LCD model of my notebook. The service tag is VQCNQ, which should have:
0819R ASSEMBLY, LIQUID CRYSTAL DISPLAY, THIN FILM TRANSISTOR, 13.3, LATITUDE CPIA, LENGTH/LONG
3122T BEZEL, LIQUID CRYSTAL DISPLAY, THIN FILM TRANSISTOR, 13.3, LENGTH/LONG, CPiA
However, on eBay it is generally written a longer part number, such as LQ13X02C
Can you help me in identifying exactly my LCD?
-I guess that the problem could also be related to the internal cable and/or the inverter (I don't actually know the real function of the latter). However, I wonder about compatibility issues. I mean, if the LCD monitors are not compatible if different, the reason cannot be in the dimensions or in the motherboard plug, because the notebook is exactly the same. The only thing I can think of is that you have different cables/inverters for different LCD. So, if you buy another cable/inverter, you could also buy the relative LCD, even if different from the one I actually have. Is that right?
Your help is really appreciated. I need to understand these things, before trying to buy a new LCD for my Dell.
Thank you,
Stefano

If you get as far as removing the screen, try reseating the flex cable. Flickering is due more to a bad connection and not usually a faulty LCD. It's also a lot cheaper!- I will try it.
The only thing that puzzles me is that the problem arises only after some usage. Sometimes one hour, sometimes half an hour, sometimes more than two hours. It could be related to heat. I'm not sure if it can be related to a bad cable seating. In this case, the problem should be fairly constant. But these thing are impredictable...
What do you think?
In any case, thank you for your advice. I will let you know.

There is one cable from the motherboard that splits into two at the back of the screen. The smaller part goes to the inverter and the wider section goes to the LCD. The cable is probably ok. Just remove and reseat the cables. A bit fiddley but it works wonders!- Thanks guys,
I also think that the cable may be the problem. Are the cable and the inverter the same thing?
Moreover, can anyone from the Dell Service tell me all the certified compatible LCD for my model?
And the cables/inverter? Are they always the same or should I pay attention?
Thank you,

The inverter is the small thin board on the edg of the LCD. Part of the flex cable is attached to it. If the inverter fails you get a very dim screen you can hardly see. Your inverter board is ok.- From your last bit of information, it is very likely that the inverter is failing when it heats up to a certain point. The time it takes to reach that point can vary due to ambient circumstances. The inverters are readily available on Ebay at very reasonable prices. You should insure that you replace your inverter with the correct one for your LCD and computer. There are model numbers on the inverters, and you should confirm with the seller that their numbers match yours.
