Gold behind some laser printer LCD displays

This was pulled from a HP laserjet printer. Removed the circuit board right behind the LCD display. Just wanted to share this.

Yup, you'll also find those boards on fax machines.

My full time job is repairing Business phones and most of the LCD boards in them are like that. I found that a lot of them are also gold plated under the green coating.

Some telephones, calculators, industrial equipment, fire panels, it seems as though 60% of the small lcd screens have the gold behind them. My buyer pays finger card price. :-)

same here finger card price is sweet it make take more to add up but these are like the bonus ontop of everything else inside

Im thinking $7 per pound on those because there is no excess metal or caps on them, id put them halfway between fingercard and slot cpu, ive seen alot of slot cpus that have lower gold per weight than that type of board. I think you could get as much as $10 per pound. Honestly it is not far off of being gold ram grade, if it had a double sided finger i wouldnt hesitate to put it in with gold ram.

A few faxes & laser printers I have scrapped down have a 'light bar' (my words) inside them. Its a long, sometimes ceramic, bar with a row of LED's on it.

The ceramic has a gold plating on it & all the LEWD's (sic, I lightly sliced my thumb today & have to type with less fingers & mouse with my left hand) LED's have gold wires going to them.
Normally they are under a strip if silicon looking goo.

I found that boiling the goo in turps & then pouring the turps off & evaporating any liquid out of the goo, turns it into a breakable solid.

Also, old faxes that cut the paper have two metal bars of high carbon steel, like parting off blades for a lathe. These would be saleable, I think, along with the steel rods, to home engineers.
