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
That other heatsink, Q601 and per the marking system, IC601. If there is no short after removing the rectifier, replace that with a good one and check it with incandescent light bulb connected in series with the power supply just to be on the safe side.

Re: Dell 2007FPB teardown
A second 'thanks' to the forum and its members - another SMD resistor on the USB board failed and was replaced - R52 47K this time !
It lives again ! |

Additional burnt problem here: In my 2007WFPb the IC601 blown up (and some other resistors too). The resistors have been identified but the IC601 complete unreadable. Shall I use 2407 schematic as reference or anyone can give me the written code. I would appreciate. |
