Re: Dell 1704FPT

Things happen slowly in my country....anyway, I finally fixed the monitor and am looking at it right now. In the end, I purchased a new inverter board on ebay for 20 bucks. I couldn't locate any bad caps (but are sure there were some) I took a chance that the lights were ok and went ahead with the purchase. I will post again if there is any problem with it. So far so good, but it has only been switched on for 1 hour.
Thanks for all the help everyone.

hi Rtech, sorry for the late reply but couldnt get back to this project until now. Resistances of the secondaries are fine. A = 459 , B=434. all cap's look ok, no signs of any problems......will check them with DMM when I get a different one that can check farads. (I think I have one in work somewhere).
By the way, I can see the screen when I shine a flashlight on to it.

I am wondering if anyone has resolved this issue. I too have one of these Dell monitors that displays a screen for less than a second before going blank. I too have noticed a burnt R125 resistor (but still seems intact). I was thinking of replacing the inverter board but am reluctant to, if it is just going to fail again.

I suspect from reading other forums that one of the lights may be gone and that the...
