Hi: I am trying to repair a DM800se that doesn't power up (no power - blank display). 1. I've started following the 12V diagram and I see that both Q1100 and Q1101 receives 12V but no 5V in any of the pins 2. I've switched off and disassembled PCB and started to check resistance Pin5 (5V) has 1.2 ohms Pin4 (3.3V) has 91 ohms Pin3 (2.5V) has 3.35k ohms Pin2 (1.8V) has 29.8 ohms Pin1 (1.2V) has 409 ohms 3. As far as I've read, it "seems" that there could be a problem with the 5V supply so I started removing "jumpers". 3.1 I've removed R1131.........same resistance values as mentioned before. So I've soldered "jumper" again. 3.2 I've removed R1112........here pin5 gives me 1.18k ohms (pin4 still 91.8 ohms). What should I do next? What this could mean? Thank you so much for your guidance in advance. Br, Francesc.
