Anyway, Wilba has kindly posted off a new LCD and I try a few things first with JBL at 5V. In Wilba's words "I would probably suggest leaving JBL at 5V until you know everything is working and switch to 12V if you're confident you have a stable and low enough voltage at the 12V rail (i.e. it's less than 12V not more). Or just leave it at 5V and keep the brightness down to less than half way."
Wilba sent me a new LCD display and a 337 transistor. I've put them in and everything works well :D
Which combination of settings do you use now and is acceptable for you? I'm also afraid about burning my inverse LCD which is labelled with 5V. :shocked: Now I'm using 5V jumper with low current (no jumper) and it seems not enough bright even turning contrast whole up. I'm thinking about 12V from my power supply OR high-current jumper at JR4, but don't know about suitable power supply in the first case or maximum allowed heat of 7805 in the second case. :unsure: Thanks for any recommendation.
