Question about Dell UltraSharp 1908FP Monitor

1 Answer

We have 90 Dell 1908 FP monitors that are failing one by one. They have power to them, will flash a picutre briefly then go black. We have checked everything including power cable but nothing brings them back. They are 3 years old and used in a classroom setting day in and day out. We have not had any power surges that the building engineers could detect and they didn't all fail at the same time. Is there a fix or something that can be done?

There is a fix for this kind of problem with your monitors.
There are things to check first to find out what the cause of the troubles.

1. It could be a bad capacitors in the power supply section of your monitor...If you turn on the monitor, examine the LED indicator lamp, if this lit green and a few seconds turn red, then you have a blown or leaky capacitors in the power supply section. When you open the back cover of the LCD (which I do not recommend if you don't have the skills. ) and separate this from the body frame, the part where the ends of the vga cable connect to the monitor is the power supply section. You can visibly find which blown capacitor is, replace this with exact value.

2. It could be the inverter board or the inverter lamp busted..... if you turn on your computer and flashes the screen for a few seconds and the led indicator lamp lit steadily green but the monitor screen is black, then backlight inverter lamp is busted or the inverted transformer is burnt. Open the back cover, after separating it from the body frame, separate also the screen. The inverter lamp is located in the upper and lower part of the screen. The source of the supply is the inverter board.
You can purchase a replacement inverter lamp from shopjimmy.com

Good luck!

Dell 1908 FTP Monitor turns on and shows picture but in just a few seconds then goes black


check all connections. then separate the wiring so it doesn't touch. sometimes the cross-talk caused by wires touching can reroute the signals. good luck.

This is usually down to the cable and fuse rather than the device. You will need to buy the right power cables/power adaptor to have the device work in that country

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Look inside for bad caps with bulgng tops, worst case will be shorted out transistors in the backlight inverter circuits or bad lamps. Check to see if you do have he 12vdc for the inveter circuits. See example of failed monitors with bad caps here: http://s807.photobucket.com/home/budm/allalbums

POWERED ON MONITOR, FLASHES ON, THEN GOES BLACK, MAKES NOISE


This is general LCD monitor advice. I don't know your specific model. Your problem, however, is very common on many different monitors.

In 90% of cases, the problem is one or more failed electrolytic capacitors on the power supply board. They are a simple matter to replace, but require desoldering the old ones and soldering in new ones, as well as general electrical/electronic safety practices.

If what I've just said already makes sense to you, then you're probably qualified - go ahead and replace them. If I'm talking greek, then go find an electronics nerd - some goofy looking guy wielding a soldering gun should do.

Dell Optiplex GX260 Tower flashing yellow power button


Hi

Power up the Optiplex GX260 and check the QUAD Pack Diagnostics LEDs (located at the back). Compare the LED pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1167139 for more info.

Ideally, to troubleshoot and resolve the issues, try removing all PCI devices, disconnect all external devices/peripherals including keyboard and mouse. You may leave the Monitor connected. Power up the PC and check for successful Power On Self Test (POST). If POST completes (generally fails on "Keyboard not present"), shutdown, connect keyboard and try POST again.

If all goes well, install PCI devices one at a time and test successful POST. This will help identity a failing device.
If issue persists, after removing all devices, remove the CMOS battery for about 90 seconds and try POST again. If same, remove all DIMMs (Memory) and check for beep codes. Compare beep pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1176760.
NB: Ensure to remove power lead and press power button briefly to use up flea power before working in the system.

If the system beeps, it suggests that the CPU and systemboard are "likely" fine. Install one DIMM at a time and test successful POST. If there no beeps then the systemboard and/or CU is/are at fault.

Regards
Mike
