Anybody had any experience with Dell 1505fp lcd monitors? I have one that's dead to the world.No lights, nada. It has one of those integrated power supply/inverter boards. I checked most of the caps on both the controller and the power supply and I didn't find anything bad. Some of those small can smt caps on the controller had between 3-5 ohms esr but still rang good on my sencore lc103.All other cap function tests showed good. They are no blown fuses. Does anyone have any input? I don't have any experience with lcd's other than changing ccfl's once in a while. Thanks guys

Re: Dell 1505fp dead
Hi aceshigh!
Are there any voltages at all out from the psu, backlight?
Have you managed to find out which pin is the PSU,s on/off if so check for any dc at the secondary side if not hook up the scope and check for any start up pulses, had one lcd monitor which was dead found out that as soon as a load was connected to the psu the output voltage dropped to nearly zero a optocoupler was the culprit, don't recal the brand.
What kind of switcher does your psu use?
