SOURCE: Dell 2407wfpb lights on but stays blank..

Shine a bright light on the screen and press the Menu button... if you can barely see the outline of the menu come up in the middle of the screen, it means that your inverter / backlight needs to be replaced. You can get a new backlight / inverter for relatively cheap, so if you can do the repair yourself, it's worthwhile.
Otherwise it's the LCD panel itself, in which case you should go monitor shopping.

Dell 2407wfpb won't turn on. No lights, nothing. Pic of back side of main circuit board below. Is this worth fixing? Matt


Matt Mathew,
The board looks burnt. You could possibly do a search on ebay for this board. Users do sell monitor parts. Dell does not sell monitor parts.
Thank You,

Can someone identify the part number of IC 651 and Q654 in my 2407WFPb Dell Monitor?


Why are people giving their opinions rather then answering the question? My monitor just died and I need to replace the main power filter cap and transistor Q654, I need the part number for transistor Q654 as I think the OP does as well.

Dell 2407WFPb made a 'pop' noise about 3 seconds after the ON button pressed. The monitord did not show any images. Pressing the ON button now does not cause any illuminitation of the ON/OFF button or any...


About the only place where this is likely to occur is in the inverter for the backlight. Although I have repaired several thousand switched-mode supplied and your guess about electrolytics is probably correct, they are probably more stressed in that inverter than the main supply but checking both will be simple once the monitor is open.
With that popping sound, you may not have much trouble locating the culprit; once their internal losses start climbing, they run warmer, then hot and do then 'pop.' If you don't find one with the top ruptured, look at the base of all polarized caps because the rubber seal is often the first to give way and there will be signs on the board of their demise.
If you can locate the bad one(s), check with Mouser(.com) and look for caps rated for low ESR and if available, switched-mode use. They are a few nickles more expensive but if the mfr. had used them initially, you wouldn't have anything to do right now. I recommend Mouser since (last I used them) they had no minimum billing and charged only the true shipping cost.
Good luck-

The monitor just made a pop and no longer works. How do you take apart to check if there is a fuse


2407 is almost the same as 2408 picture I have here, just be real careful not to move the front bezel too far from the chassis or you will break the cable! Use thin flat blade screw driver or special tool as shown in the video and work around the bezel REAL SLOW!

Monitor is dead - tried swapping cable. Had a power blip a few minutes earlier. Does the monitor have an internal fuse?


Rupert597, It should if unit's ac line cord is plugged into a outlet. Do you have a SURGE or TRANSIENT voltage protected power-strip connected to your GEAR!!! 12fixlouie

Dell Flat Screen off/on switch broken


Mohons, Get with the the program, will ya!! A video clip is worth a thousand words!! Try a search at YOUTUBE for the longer 6 to 10 minute video clips of "LCD monitor disassembly" and "LCD monitor repair". Here is a clue. "Parting the rear cover from the front plastic bezel is the hardest part." Go watch some video. You will be glad you did. And while your inside the monitor, why don't you check the "switch-mode-power-supply board for any swollen and/or leaky electrolytic filter capacitors! Do you have an OHM-Meter or DVM to check the switch? Bye for now. 12fixlouie
ps. could be SMPS is not "listening" to a GOOD switch!

Dell 2407WFPb Monitor will not reset to 1920x1200


In display properties or ATI utilities, there may be an option such as 'hide modes this monitor doesn't support' or 'show all modes'. If so, you may be able to set your resolution by using this option.

Also, check in the BIOS for any settings related to display mode support. Otherwise, you will need to contact the Mboard manufacture site for possible BIOS settings probably limiting access to this resolution.
