I have a Mag monitor that I'm looking at. I don't get 5V to the start up citcuit. The 12 v are all there all the ICs on the main board have there voltages and the power switch works. Is this a main board oissue then with the MCU. I don't have a schematic so I can't trace the start circuit on the main board but on the Inverter board it is not there at all not even at the connector. Any ideas.

I tried searching Google and got: about 6,650,000 for Mag 17" monitor.

I'm NOT about to check them all.

Can you narrow it down a little?

I can save you some time there is not much out there. I know how to search on Google. I don't want to pay for schematic and I belong to a couple sites and no one seems to have one. On the back of the monitor it says product # LT776s which seems to be the # that everyone goes by, the model # says 780 which really I see a Proview monitor come up as . Are Mag and Proview one and the same? Do you know anything about the MCU. Is the start circuit the EN ( enable) on the IC. I don't see voltage there either. I don't think you really have to know specifics about the partcular model just how a start circuit works on the main board is really what I'm looking for and I would guess that that is pretty similar on all monitors. They all have a MCU that needs to be enabled. I have never run into a monitor that didn't have the start circuit voltage at the connector to the inverter board just usually bad Q1 or Q2 on the inverter or pico fuse. Once a bad inverter IC. Be great if you drum something up.

Thanks paul
