Service Laptop Hp Compaq Cq41 Intel No Display Tidak Ada Tampilan Di Indicators of this problem may be missing digits or segments in the screen, or the calculator not working. corroded circuit paths: you can only see it if you open the calculator. My trusty 42 year old 41c has a display problem: when powered on, it blinks the display briefly and then goes blank. quickly holding down nearly nearly any key shows the function or key pressed, but when released, the display quickly fades away again.

It could be a zebra strip contact problem, which usually can be solved by cleaning the strips. but it could also be an lcd connection pin soldering problem. the solution for the latter is to resolder the pins on the keyboard pcb. the four screws are under the rubber feet. The root problem still exists today in all 48s g series lcd's but the occurrence is extremely low. the condition is when all top row annunciators are on without excitation.
