1800FP ICE chip

Thanks a lot,

I think I am going to order the ICE chip and solder it into the circuit. Are there very specific chips for each monitor or is this something I could just pick up from any old electronics store?

The ICE chip is not so easy to get. Your best bet is to use the ebay source. cheap quick and easy. It would need to be an electronics wholesaler, a trade type distributor to get that part. Most would not stock it.

Inside there is a IC chip on the power pack that goes bad, replacement is called for also look for bad capacitors when you are inside looking around, those need to be replaced as well
hope this clears things up. dells third party who built these units did a rotten job on this model. that chip always fails.

Ice 2as01 is broken again


Resolder diodes D903 and D906 in the secondary of power supply. The diodes are the two mounted to a heatsink. These are the reason the 2AS01 goes out in the first place. The solder joints on these two diodes breaks loose. If you don't solder them, the 2AS01 will go out again.

Dell 1800FP - no power


Hi pcpiuk

If you have a multimeter, and want to get into the electronics of it all, you could rip the covers off and sus it out. Here is a pictorial guide on whats in it. You need to check the power supply for operation. If it appears to be producing voltage(they usually do or they dont) then it will be ok. The common cause of failure in the power supply is the regulator IC ICE2AS01 an 8-pin DIP chip, and resolder the entire PC. Around power devices I use solder with 2% silver content as it creates much tougher solder joint. If the power supply checks ok, then the inverter is the next spot to check. Just replace it if it appears to be the problem. You can get spares to rebuild the power supply and even new boards from ebay or Dell direct.
If you have any trouble getting parts, comment back to me here.
I am more than happy to answer any other questions you may have about it, please get back to me here, or use the ASK function to go straight to me :) If you are still unsure, have problems, or we need to look at the situation more deeply, then before you give a rating for this advice, hit the ASK button Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you.

Dell UltraSharp 1800FP, green power light, black screen....


Its probably the inverter that lights up the screen that went bad.I have replaced inverter before with much sucess. If you feel comfortable opening the unit up I found one on ebay. Here is the link.

Dell 1800FP Dark, No Power but power supply seems fine. Help!


I just repaired 3 1800FP's - all dead, no lights.
Firstly a dead 2AS01 is 95% of the problem, because some fool designer left out the protective zener diode - cheapness.
Mouser Electronics does not have this part, but lists it at 37 cents in lots of 2500, and gettable at $2.66 somewhere else.
You must also replace the two small value electrolytics near this IC, as some had an ESR of 40 where <0.5 is where it should be.
I suppose as the electro's dry out, the spikes can zap the IC. The quacks on ebay flogging 2sa01's alone, probably hope to sell you another one down the track (at a fat markup).

There are 2 'Sam Young 2200uf' electros that really should be replaced, with ESR or 2-30 ! Ideally replace ALL electros, as the others will be off - but those 4 as a minimum and using a jewelers loupe, resolder other joints on the transformer and anything that looks more dull silverish, than the rest. A 1 inch used and worn paint scraper will get the case open easy.

DANGER, CAUTION : Finally when refitting the inverter board, ensure the steel tab is over the TOP middle of the board facing away from the power socket (SO YOU CAN SEE IT) . The board sides in flat. It is possible to scew the board down with a slight bend, with the tab pressing over the pcb tracks - very , very bad!

Now all I need is for some kind soul to improve the fix by stating what the value of the missing zener should be.

PS. Just because the caps are not bulging does not mean they should be OK. Most wrecked 10 year old power supplies have better ESR's, so the electronics must be hot under the cover.
I have seen bulging caps with a GOOD ESR, and non bulging ones with an ESR of 47.
