Re: Dell 2007FPB teardown

OK so I've replaced the bridge rectifier and the fuse and now the monitor is up and running, thanks for the help.

Re: Dell 2007FPB teardown

Yes, I shorted it while connected to the grid

Anyway I've taken the capacitor off the board and now there is no resistance, it's not shorted so I guess it's ok.

Bridge rectifier BD601 - each pin is shorted with each pin (measured it while removed off the board), + and - pins have some burnout on them (see attached pic) so I guess it's dead ?

Fuse F601 - measured it taken off the board and it's open circuit so it's also dead.

Which are the switch and controller elements ?...

Re: Dell 2007FPB teardown

OK I think I got the pins I needed on the power board on the connector towards the inverter (marked on the first picture). I've tapped directly on the connections from the power board towards the inverter and left the inverter board disconnected, just connected the LED driver board on it's place. All went good, the 2 LED strips lighted up when hitting the power button, I've assembled back the panel and tested it again - the "No input signal" box appeared on the screen, jumping up and down. At this point I wanted to test the brightness adjustment...

Re: Dell 2007FPB teardown

Guys,

I have a 15 year old 2007WFP, which is has been a faithful servant until recently when it developed the notorious 2 seconds to black issue. I've taken it apart along with the panel and when powering it up one of the six CCFLs does not light up, the other 5 light up and shut down shortly so I got a faulty CCFL.

This is where I decided to try and upgrade it to LED backlight, ordered this kit:

And the obvious questions...
