Diagnose & Repair Dell 2005FPW LCD Monitor

In a change of pace, I do some electronics troubleshooting and repair of this Dell LCD monitor. And say a few choice curse words (bleeped) along the way.

For such an expensive monitor (when new), the design is crippled by STUPID choices, probably made by a bean-counter. (The primary unit failure was due to crap no-name chinese junk electrolytic capacitors.)

The trick to getting around the ribbon cable is to pop loose the front farme, (using a long thin metal spudger  sliding it straight in along the frame they tabs will just pop free without breaking) and after you have all of the frame free, lay the monitor on it's face and lift the back off, where you will see the other end of the cable and disconnect it there.  It's actually very easy once you figure it out.

SUCCESS!! The parts came in today. I swapped 12 caps. My values were differerent than the service manual parts list. I just went with the values on the board. Everything is back to normal. No cracked screen. Easy to snap back together.

Thanks a lot for this. I only replayed to two capasitors on the logic board. Repaired the flickering.

I had one of these monitors and managed to get it open without breaking anything. It started turning off and rebooting randomly and I suspected bad capacitors so I bought a capacitor kit which contained replacements for all the garbage quality capacitors on the power supply board, some of which had bulged. After replacing them all I got it back together and it is still working for my wife's friend. A lot of electronics manufactured in that era had this problem and it was because several Chinese manufacturers used a defective formula for the electrolyte used to manufacture the capacitors. Dell actually got sued because they had a bad batch of motherboards that failed prematurely.

I appreciate how well you explain the issues. Good video.

My 2005FPW has a power board problem--inverter starts the lamps for a quarter second, I can see the "DELL" splash screen from the logic board, and it goes black.
My disassembly went okay when I saw the pictures in the service manual:
Hook fingertips under the edge of top bezel, between LCD panel and plastic, gently bend up and out.  Catches will disengage.  Work around to upper corners, do same on left edge, right edge and finally bottom edge.  Do not try to remove frame yet.
Put monitor face down and remove black plastic back panel.  Gently unlatch thin cable from button board from electronics.  Remove front bezel.

I did 2 of them - however one of them seems to have a broken backlight even though I cannot explain it... Both tubes connected, the psu makes a high frequency hiss noise for 2 seconds then switches off the backlight. Connecting either one of them is OK - however when connecting a different panel, both tubes, everything is fine. WTF.

Sorry about the end result which was beyond your knowledge
HOWEVER
Its been very useful and I'm glad that you had uploaded. Subbed & liked.

Scroungi...I have a Dell E228WFP which looks very similar to yours...I've found a better way to remove the crappy front bezel frame without inserting any tools and chipping the sides of the back plastic panel. Very carefully grip the bezel frame from the screen side and pull upwards and away. It snaps out much easier with no damage to the screen or bezel. Looks much better as it looks like it was never taken apart. I have a black screen problem with no green or orange LED illuminated. I found 2 bulging Samxon 470uf 25v 105C caps at locations C858 and C864. I'm going to replace them and hope it works. Thanks for a great tutorial.

Thanks for the Ilustrating in this video the way to fix this monito! This so helped me to REPAIRED my Similar HP 2405FPW with it come almos with the same specs but it s a really way better manufactured model! Mine was only having one set of six 470uf charged @ 35V really messed up, but I replaced them all the power board and it works LIKE NEW! :-) Thanks a BUNCH from NYC! Best of luck

Wow man! that was a crazy ending! was not expecting that!

Thank you for sharing this video. Besides some bad capacitors, I run into another problem with this monitor type. A broken backlight wire. I can hear a hissing sound and smell ozone in one of the corners of the lcd panel. So I am not finished yet...

i have a dell 2405FPW and it sometimes the display turns off / black for a fraction of a second (the power leds stays on / do not flicker) - sometimes it goes off on off on like 10 times and sometimes it then stays off for some seconds. then on other days it can work for hours without any problem. do you have an idea what this might could cause or how to fix it since i do not want to throw the monitor away if its easy to fix :). the problem is unrelated to the computer in use - the monitor behaves the same on different machines.

Hi Master, I had a broken ceramic fuse "F801T3.15A/250VAC". But I can't find this type of fuse in my city. Could you tell me PLEASE, can I use the fuse ""F5A 250V or F4A 250V" instead of it ???

This thing came out in 2006... This video was made in 2014. The thing lasted for 8 years. If that's "junk" then there is no hope left.

[MrDLRu]

Great job on the repair work though, thanks for sharing that. I have a Hell...I mean Dell 2007WFPb and what it's doing is just completely shutting off after its been on awhile. It will then turn back on and maybe stay on or shut right back off. Does this intermittently, on/off/on and it may even stay on for a long while before going through the same routine ....Do you think it's the capacitors or power supply issue?

Thanks for the video, hope it's similar enough to my U2410 (same problem, no power) for me to attempt.

I wonder if that monitor was made were the off name cap companies were using a incomplete formula, the one thing was missing an anti-corrosion to were the electrolyte eats its metal casing.

I have an Asus VS247HP. Just the other day I noticed very light diagonal grey lines across the screen. I've tried the monitor on a different PC, and they still showed up on my other PC. I really don't know what causes them. I don't think they lines are from pixels. It looks like they're on the outer layer of the screen, but under the outer layer. It's driving me nuts. I really want to know what causes this so I can prevent the issue from ever happening again.

Damage to bezel frame shown in this video is result of wrong techniques of prying bezel and unhooking button cable from wrong end.  See my other post.
Now I know I have a burned transformer coil on lamp power output, so I will buy a $50 power board replacement and drop that in--much simpler.
