Having problems with your Dell UltraSharp 2005FPW 20.1" LCD Monitor ?

Front panel lights blink on/off once per second

\015 \015\012I am a bit dismayed with the fact that several of your users reporting the same/similar problems, and then only to be told that they need to replace the backlight inverter. This particular problem has nothing to do with the inverter..however, it has everything to do with the logic board.\015\012\015\012Regarding my experience, if I let the monitor sit for a few hours/days, it will then power up normally for up to several days, with one exception. The indicator lights that are there to inform you what 'Source' mode you are in will not light up. Furthermore, I cannot change any functions via the "Menu" on the monitor...such as the brightness/contrast settings, split screen, etc., or change sources.\015\012\015\012If this "blinking" problem that affects so many were truly an inverter failure, then the monitor screen wouldn't ever power up, which is totally different and seperate from the logic functions, such as video source control, brightness/contrast/color controls, etc.\015\012\015\012I ran my monitor for 38 months 24x7 in my server room. Never once did it ever have any problems until just two weeks ago. I came in one morning and moved the mouse as I usually do to wake it up from its sleep mode, and suddenly, all the front panel lights...including the power light would just blink green. I could even see the Dell Ultrasharp message/logo during each "blink" on the screen. If I kept at it, and time it just right, I could turn off the monitor with the power button, but it was just easier to unplug the power cord.\015\012\015\012People need to use common sense before they make a 'diagnosis' like this. Inverter failures will result in total loss of picture, and does not cause any logic failures such as blinking of the front panel lights, which is controlled by the logic board...not the inverter.\015\012\015\012So, the real questions that I ask on behalf of all of us who have had the same problems...how do you open up the monitor for repair (assuming I found a logic board replacement), and where can you find a replacement logic board...(besides Dell of course)...but Dell I believe, does not manufacture these monitors themselves, so there must be another source(s) other than Dell.\015\012\015\012Just remember...inverter failures causes the screen to fail, but the indicator lights to remain on, whereas a logic board failure results in the screen still able to function, but you lose complete control of the front panel controls..."sleep' modes, etc. In other words, control of the monitor itself. With a logic board failure, all the front panel lights will blink simultaneously, if there is a signal present (doesn't matter what the source) the lights will blink green), if no source is connected, the lights will blink amber in color.\015
