Well I can't help with any of those numbers either ... dell part numbers are generally 5 digits & with a bar code so as you say not them ... mmm but 'soldered on' - won't I think have that, so I don't think any of the numbers are dell bits ... But you think the displays an hitachi one anyway?, but I dunno about them !

Can you furnish us with an image ? .. maybe...

Stumped!
