Having problems with your Dell UltraSharp 1905FP 19" LCD Monitor ?

I have a 3 yr Dell UltraSharp 1905FP LCD monitor. Recently, when I turn it on, the power on green light would blink continuously for about 1 minute with no picture before the light become steady green and have picture (everything working). Now it is up to 5 minutes. Other than waiting for the monitor to display the video, everything is fine. It acts like it is waiting for something to warm up. Does anyone know what is the problem? Thanks.


Answers :

Yman1949, Your 1905FP unit is not working as it was designed to do! Here is something you can relate your problem to. The white light needed to see what is on your lcd panel is produced by "cold-cathode-fluorescent-lamps" (2) that require 600-1200vac to start and sustain the fluorescent light output. If the DC source (switch-mode-power-supply) or the CCFL's electronic ballast circuit (inverter) fails you will have a black SCREEN to look at. However, your problem is just a little different, yet still a common one that can be dealt with in the same manner as any lcd with a faulty SMPS or INVERTER circuit. I highly suspect that over time (3yrs) this unit has developed a (1, maybe 2) "thermally stressed" solder joint(s) in either of the two circuits, and have now turned thermally intermittant. Once that occurs, the gases in the air we breath start to play a major role in making the problem WORSE!! They now invade the void in the thermally FRACTURED solder joint, and begin to OXIDIZE the metal (tin,lead,silver) causing more resistance in the surrounding area, thus taking your monitor a longer period of time to turn on than before. If the monitor were to have warm air force fed thru the rear ventilation slots prior to turning on the unit, to warm it up from being off all night, you might prove out this therory. This unit might be fixed quite easily with just reheating a "frosty" looking solder joint on a printed circuit board. Finding it is another thing! I use an old WWII surplus inspection microscope to find them when a magnifying glass can't cut it!! Well, yman1949 let me know what you find out, lmistyrel
\015\[email protected] because I'm curious. You can do additional comment when you have time, after visiting YOUTUBE to watch some video clips of "LCD monitor disassembly" and "LCD monitor repair"!!! The longer ones are better but none have purchased any CLOSE-UP lenses to show any real close-ups required to SEE the PROBLEM of HAIRLINE thermal fractures of power transistors and inverter "step-up transformers" on the suspect boards. You may also visit a site run by another tech on fixya. www.ccl-la.com/badcaps.htm who also knows about the common failure modes of the crappy far-east junk monitors we import into the USA. Pay particular attention to pictures of failed "electrolytic filter capacitors that have "swollen/domed" looking tops that mayor may not be leaking stuff out the top or bottom!!! Good luck and I hope to see some stuff added to the above request. I'm 12fixlouie aka louie12fix
Try taking the Monitor to factory settings. Check for Monitor power options in the control panel. Check for your video card, it may be that Video card is delaying the Video output and its nothing wrong with the Monitor.
