Sorry, I'm wrong, it worked for me too.. in the past, also with 16F690.
I may have a problem with my breadboards. Gonna buy a new one today.
Nevertheless, what I see on my LCD display is on it's first line, a row of blocks, slightly visible.
Of course, I tried to change the contrast, but nothing helps.

I never use a contrast pot, I ground pins 1,3,5,16, put power on 2,15 always works for me. Those breadboards get nasty inside, corrosion after the plating wears a bit, the component pins wear the contacts quickly too.Originally Posted by flotulopex

No pot on my side too.
I use a 1k2 to 2k2 resitor instead.
Must be the breadboards...

Still not working!
Just get a row of black blocks.
any one else able to get this working yet?

Just a row of blocks indicates either contrast is too far + or no pic signal. Not meaning to offend or agitate, but you did look at the pic pinout in the data sheet, yes? I ask because this PIC has a somewhat convoluted pin arrangement and it is easy to wire it incorrectly. Is your programmer up to this chips needs? Most PICs like 16F84, 16F628 . .. have power in the center of the device but this has them swapped side for side and at 1 end, your programmer might not know this. I programmed mine using PICKitII and low parts count demo board made for 16F690. You might have to set up for ICSP to properly program it.

I just found what was bothering me: wrong oscillator fuse setting.
Couldn't see this for hours.....

It seems the more simple the problem is, the better it's ability to hide.
