Did someone try to use the LCD with 3 buttons and 3 LED's sold on the PICLIST web pages?
I tried, double checked (triple-checked) all connections, and I'm unable to succeed with the "hello world" example.
I get only a "dark" first line. I tried to play with the example program, without any success. I do not think there are errors in the provided schematic, as, as far as I know, no one made a remark on the PICLIST pages.
Thanks for any hint.

"Modify" your post here and fix the link.
Explain (post, using "code" tags) what code you think you are using.
Insert a perfectly focused photo of your complete setup (please do not "attach").
Nowadays, I only like displays with backlights.

I don't know if I am looking at the same page as you since your link is still broken. The page I am looking at shows a very strange pinout which may or may not be correct.
I would try connecting your device following the pin numbers 1 -14 as specified in the LiquidCrystal tutorial while ignoring the pin labels EN, DB0, etc on that PICLIST diagram.

What, this one or the corrrected link?
Obviously this panel is not wired the same as those with which we are familiar, but then again, there is no reason why it would be. 
Yes this is the schematic I have, and which is given on the PICLIST.
By the way, you are right the link was corrupted??? The second one is OK.
Pin-out seems strange, but as it is rewired inside the PCB, it should be OK!! There is no access to the original LCD pins, so I cannot check.
Thanks anyway.
It is not a matter of "original LCD pins". This is a single assembly mounting the actual liquid crystal panel and the driver ICs. It performs the same function as the common displays available through various sellers, most notably eBay.
But it is an alternative form, not an adaptation. You should not think in terms of either form being "correct", it is just what it is and there is no "standard" for the pinout with which it is to be compared. Any given module generally has a pinout which reflects the pin sequence on the HD44780 chip and indeed the only variation here is the order of RS, R/W and EN.

What about the order of the eight Data pins?
