Hello there, this is the first time I have posted on this forum although I have successfully used other threads to repair monitors in the past, so a big thanks for that!
My problem now is that I have inherited a 24” Dell monitor which shows no signs of life at all, no power light, nothing and I'm a little stumped as to how to proceed. I have posted pictures of all the boards that are in the thing and I'll try to explain how far I've got poking around with my multimeter. I hope someone can help me fix this thing as it would be a shame to bin it cos it's massive!
All caps look ok visually but I know this isn't a sure sign of anything!
Nothing looks burnt or burst and nothing seems to get hot to the touch when power is on
When power is applied I get a reading of 290v at the other side of the fuse next to the power in connector so I guess the fuse is ok. The big cap gives a reading of 407v.
I get a reading of 23v from the caps on the inverter board.
When I try to get a voltage reading from anything on the wee board next to the main board or the video board I get 0v readings, as if the power isn't getting from the main power board to them.
I have tried powering it up with the inverter board disconnected and with the lcd itself disconnected with the same result- nothing.
Any thoughts?
