Desktop clock
« on: October 06, 2017, 01:41:32 pm »
Hi everyone
My friend has an old LCD damaged desktop clock.It's very valuable for her.It has LCD display that is no longer working.I would like to make it work again.I couldn't find any similar. I think I need to change Lcd display to 7 segments led display or something else. Have you any suggestions?
thanks.

No longer working...  let us know exactly what that means.

Typically there are segments missing, or dim. Typically it's the Z-strip ends are dirty. That would be the rubber thingy between the display, and the PCBA.

There is a difference between 100% isopropyl (use it), and rubbing 70%... (the addition of 30% oil). Do not leave any dirt/fibers on the contact areas.

Stop being vague. “Broken” doesn’t say much more than “doesn’t work”. Can you please describe the fault EXACTLY??

Do you mean you cleaned (“wiped”?) it with alcohol? (To whip something out means to pull it out to show it... usually referring to a guy pulling his dick out of his pants.)

In rubbing alcohol, the balance of the alcohol content is water, not oil. (70% alcohol, 30% water happens to be the best for disinfecting skin — even better than higher concentrations apparently — but indeed for electronics, a higher concentration is better.)
