SOURCE: HOW DO I OPEN THE CASE OFTHE DELL FLAT MONITOR

tonylad, Remove the pedestal by taking out the 4 phillips screws on the back. The back plastic cover will now be able to be pried away from the front bezel along the seam on the bottom of the monitor or sides. You may want to go to YOUTUBE to see how it's done. you need to search under LCD monitor repair or somthing similar. Yes I have seen some there that are about 8 to 12 minutes view time. If you get it apart please be very careful when handling the LCD/FPD . Next you will need to inspect the the large SWITCH-MODE-POWER-SUPPLY board. Look for any swelling of the tops of electrolytic capacitors. If you find any, mark them with a marker. With magnifying glass or a inspection microscope check the bottom of the board for thermal and or vibration FRACTURES surounding the leads of large THROUGH-HOLE components soldered on the board. Also look for any really FROSTY looking solder joints. Well, anyway good luck guy. Get back to me if you find anything out. I'm louie12fix on fixya or lmistyrel @aol BYE

Dell monitor will come on but will not stay on. stays on 5sec


5 seconds? Hmm, too long for inverter driver turning into protection caused by bad lamps. Also too long for PWM controller in the switching power supply.
Rather looks like overheating of the FETs in the inverter, they are driving HV-transformers. Open the monitor, remove metal lid and observe inverter board. If PCB under and around these FETs is darkened, replace them.
These Dells hard to open. Take the foot off and unscrew plastic cover. Then using flat screwdriver with wide blade separate plastic halves of the case, starting from bottom edge and moving to opposite. It might be sweaty.

Dell 2001 fp back panel removal ?


First remove the four screws behind the stand mount on the monitor. Then turn monitor vertically so thet the bottom is up. Next look for slots betweem the portions of the srame on the bottom. Use a slotted screw driver to pry open the bottom. Becareful to not damage the plastic. As bottom is opening pry around the entire frame it will come loose. Make sure you place the monitor on a table covered with a towel in the final process to un clip the case.

Monitors are disposable items and not normally repaired. Technology moves on and High Definition Flat screen monitors are the way to go. The only place you would get a schematic for it is from Dell themselves. Unlikely you will find spares for it. If it has no power, then it is a power supply unit problem. I suggest you get a new electrical mechanic :>)

Brown horizontal lines sporadically appearing on monitor


I had the same problem. I fixed it completely today. The horizontal lines disappeared. IT IS DEFINETLY THE DEVICE DRIVER. I confirmed my monitor model tyope (dell M783s) and downloaded the specific driver for this monitor.

I had to do these exact steps or did not work.
1) with the problem screen, disabled the display adapter under the Hardware/Device Manager settings.
2) Restart the PC
3) Boot will come up with brown lines still but the screen will low resolution of 600x800.
4) Then I installed the correct device display monitor driver onto the pc. ( you may need to scan for new hardware, then choose the directory with the new hard drive.)

If you need step by step... just reply back.

Flickering switch light, blank screen


Hi, First of all it is not advisable to open up monitors without proper tools as they contain hazardous elements. Dell monitors however do have a 3 year SEPARATE warranty. Check on the back of the monitor and look for the monitor serial number. is should start with CN-xxxxx-,, or JP-XXXXX-. give that to a dell tech and they should be able to replace that.
