Question about Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor
I was referred to you by worldvet.
Here is the problem:
My Dell FP1800 LCD monitor was working fine. I was using my pc one time and the monitor suddenly went blank. The green power on light disappeared.
In trouble shooting, I checked the power cable, fuses and connection. I even used other working power cables. My graphics card is definitely working with other monitors. My monitor is about 5-years old. What happened to my beloved LCD and is there any chance of making use of it again?
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.
