Re: Dell 2407WFPb Monitor - Bad Cap
Schorsch87, take a look at the circuit diagram, post 387, page 20. The only way R603 would get fried is if the PWM module (IC601) has failed and became shorted pin 8 to pin 4. This has been occasionally reported here (e.g. post 384). If you are changing IC601, might as well change the other IC (651, the PFC). And make sure you have good resistance across Q651 (measure from D down to S).
