We did some measurements.. Replaced the tm2 trimmer, We now get 2v to 3,5v trough the tm2 On points gnd end tp1. The problem seems to be in ic118. We gonna replace this one tonight. Every other measurment between Gnd and 5v points we get the logical 5v. Sequemcer and logical led run is still not pos...

Replaced the defective IC's in sequencer.. Now i get 11,41v dc btween gnd and tp1.. No contrast on lcd anymore (had working lcd last time) I REALLY DON'T KNOW WHAT TO DO :/ Does somebody repairservice against payement? i don't think i could solve this problem without Getting fried components. Thanks...

But the 10v stays the same.
Thanks in advance!!

Hey!

I've got 10v between PT1 en Gnd measure points.
Adjusting TM2 in calibration process does nothing.
Anyone any clue?

Thanks in advance!
