Question about Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor

1800FP monitor ICE chip

Thanks for the advice. My father is fairly savvy in electronics and he basically said the same thing about the capacitors. He also noted that measuring capacitors with an Ohm meter can be deceiving based on how they are wired into the circuit, e.g., series or parallel. I think I am just going to buy that ICE chip for ~ 5$ on ebay and solder it in and see if it fixes the problem. They claim that the ICE chip is the cause of 9/10 of the power supply problems, does this sound believable? Also, I was wondering how specific each ICE chip is for each power supply. Could I just go pick up any old one, from say radio shack?

Hopefully the old thread was forwarded to you
Thanks again

You NEED the EXACT ICE CHIP, not just any old chip. They make millions of IC'S, you can get a reman power supply on ebay for cheap from ressurectek, tell him jimmyvisthekey sent you. Later.

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.

1800FP ICE chip


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.

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 1800FP has slight yellow cast


Your Display cable (inside your monitor) needs to be replaced. (Or reseated)

I would look on ebay to try and find the part and then take it to a local tech to replace it for you as I would not recommend anyone take apart a monitor (LCD OR CRT) if you had never done so before.
