Working on a Dell 1800FP. The monitor shows no sign of life. No Power LED, No Image. Here is what I have Done so far.
1. D903 and D906 both had bad solder joints which were resoldered.
2. T901 had a couple of Cracked solder joints so all pins were resoldered.
3. Main Fuse is good.
4. 165VDC across the Large cap.
5. No power at the connector to the logic board. Should be 5vdc and 12vdc
6. Checked IC901 (ICE 2AS01) for shorts pin 6 and 7 show 7 ohms. Does this indicate a short. DVM was on 200 ohm scale and shows .25 with leads shorted.
So far I have not recapped the board but I will if you think this is the next step.
Pictures of top and bottom of Power Board are attached. (Before I resoldered.)
Also what is a good source for the ICE 2AS01 digikey and mouser both show no availability and Ebay is either expensive or shipped from China.
Thanks for the wonderful resource.
