JBC JT7750 Hot Air Repair
« on: July 10, 2015, 10:48:58 am »
Just some info on a quick repair I just completed.

I bought a JBC JT7750 hot air rework station cheap which was working, although the LCD was just displaying gibberish characters.

Doing a bit of testing showed that the PIC was sending the correct initialisation steps to the LCD (for 4 bit mode) so I suspected the LCDs built in controller itself.

Controller for the station is a PIC18F6621

With a bit of google, the following part from RS appeared to be a good fit:
RS number 532-6559

Soldered in the replacement and all up and working! too easy.

I suspect the other JBC products from the same range also use the same LCD.

(White border LCD is original, black is the replacement)
