LCD do display - but pins check out

[Tabsoft]

Good luck there, sir.
Nothing like PCB Coasters! I have a few myself.

BTW what Schematic/PCB software are you using?

[Scampy]

I use DipTrace. Up until now it's been excellent and I've produced several working boards from it.

To be honest I think it's 50:50 human error / software error The nets show up for the custom part in the schematic, but were missing in the layout... still having spent two days now trying to sort this I think it's passed debugging and time to start from scratch

I get some of that green felt from the fabric store and glue it on the back so they don't scratch the coffee table......

Well after a few hours work I've redrawn the schematic and this time names each net, and give the pins on the connectors names so that everything can be traced and identified when it comes to converting to PCB layout.

It's nearly 2.30 am !! (struth don't time fly when having fun !) - let me know what you guys think

Can't really read the schematic because the picture is so blurry.

Same as TabSoft

If you could post the DipTrace files we might be able to help more.

Or a better res JPG.

Sorry guys - hope this helps

Seems the forum re-sizes the image - I'll try something else

Nope - does the same with URL's !!

IIRC correctly you only need the supply voltage and contrast voltage to see the square blocks on line 1.
So long as you aren’t driving the contrast with PWM (Melanie’s old trick), you should see the blocks with the chip unpopulated.

Thanks, I can read this one.
Since you had issues with the LCD before, can you give us the model number?
Really do not want to guess.
