Hi everyone, Here is my problem, I had the bad idea of wanting to power my fluke with a 9v transformer, but there was 12v at the output! The fluke turned on and off. I put the battery back in to check if it turned on, but the green LED on the switch flashes and the fluke does not turn on anymore! I started investigating, and I found a short circuit on the diode CR9, and the capacitors C79 and C67. The 9v voltage arrives on Q20/Q21 but not further, maybe a problem with U20? Thanks for your help. Regards Gil |
