My ProView Model 780 flat screen LCD monitor
quit one day while being used.

The 12v supply is still good, and getting to the monitor, as indicated
by the little green LED lite on the power switch on the front.

A guy in this group helping me said a common failure mode in these is a very
small
fuse inside the case. Makes sense. I was going to check this fuse,
and attempted to take the monitor apart to gain access. Then, I got
interrupted and had to focus on other things. I'm now back to the
monitor project.

I got the back of the case off, no problem. But, I didn't spot
anything that was obviously a fuse at that point. So, I assumed I
would need to lift up the board at the bottom, and maybe even the LCD
panel.

Anyone know where the fuse is likely to be, and what things I'll have
to take apart to find it?

The fuses (plural) in question are on the backlight inverter board.
They will be surface mount fuses that are approximately 0.062-.125
inches long. Each backlight inverter circuit on the board (count the
transformers) will probably have a fuse on the power line going to that
part of the circuit. If any of the inverters does not run, the whole
thing shuts down.

Most of the monitors will restart the inverters during screen
resolution change, and you may see a short flash of video for less than
a second. This is the common symptom when one of the inverter fuses
opens up on a multi-inverter, multi-lamp unit.

If you are not equipped and experienced working with the ultra small
surface mount components, you may want to practice and get the correct
soldering iron tip and solder for the job.

Thanks very much. That is good info, and I can use it.

In addition, I need to know if those fuses will be visible just by taking
the back off the monitor case? Or, will I have to lift up some circuit
boards at the bottom of the screen?

Sounds like maybe the fuses will be visible just by removing the back of the
case.

How can I determine the amperage size of these small fuses?
