Dell model E2310Hc monitor repair.
I have repaired several of these. The problem was the same in each. The power light would illuminate when the monitor was plugged in. The buttons would not respond, and the screen remained dark.
In each case, the processor board (main board) was the problem. The part number of the processor board is 715G3329-1-2-HF. The capacitors were removed and tested with an ESR meter. In each case, capacitors C704 and C707 had failed. Replacing these capacitors fixed all of the monitors. These capacitors are both 100uF 25V. There was no swelling or other visible indication that the capacitors were bad. An ESR meter was needed to show that they had failed.
I had four in a row with the same problem. I assume this must be a common failure.
If you have this monitor, and it is doing strange things, such as the buttons locking up. Then consider the capacitors on the main board.
The main board is available for purchase from several Chinese merchants. If you have the ability to replace the capacitors on the board, then you can save money. If you do not have an ESR meter, I suggest just replacing C704 and C707 empirically. There is a good chance that will fix the problem.
This is a detailed “how to” video. It shows the step by step of how to take the monitor apart and put it back together. It is intended for the novice. If you are experienced at monitor repair, you can probably skip most of it. This video does not include instructions on how to desolder and replace electronic parts. There are many YouTube videos that cover that topic.
Correction: In the video C704 and C709 were identified as the problem. It should be C704 and C707.

These instructions work perfectly on an E2210Hc too! Replacing C704 and C707 on my E2210Hc with new 100uF 25V caps resulted in a fully functional 22" monitor again! YAY! THANK YOU very very much C. David Graves for the wonderful information!
The problem with my monitor is half the screen is visible in the fog.What could be the problem?
Thank you so much 🙂
I can not thank you enough!
Serdeczne dzięki za materiał ,usterka usunięta monitor działa prawidłowo. U mnie wyłączał się po około 15 min.
Can you do a set up please
Howdy! I replaced the logic board and the screen now just flashes blue, then black, then white, then grey, then grey blue green red rows (bottom to top). From what I've read it sounds like a burn-in prevention setting, but I can't even access the monitor's menu. Other people have had the issue, but can still use the monitor when it has a video input. I cannot, it still cycles through those screens. Do you know a fix? Thanks in advance!
awesome! I got my grandmother one of these for $50 to upgrade her old 19 inch that she was having trouble seeing. had the same symptoms and replaced those 2 capacitors. problem solved.
Thanks for this!! I was able to save some money because I was planning to buy another monitor. Kudosto you sir 🙂
I have Dell E2210HC and it can do anything while broken but while its plugged in it could stay at Dell logo, or it can be glitched.
Great video! I have 2 monitors Dell 2210hc. One of them started shutting down shortly after it was turned on. I took it apart and discovered, the video processor on the main board gets quite hot, as well as the 3.3V LDO nearby. I thought it's problem with the processor or the LCD panel at first. Decided to look up on YouTube for someone repairing similar monitor, and after watching through 6-7 other videos, I came across this one. The monitors look exactly the same as mine, the internals are the same too. And guess what, turned out the problem my had was the same also. Thank you for saving me the time for digging for schematics and parts. It was an easy fix. I got very lucky finding this video!
Oh, BTW I didn't have 100uF/25V and replaced mine with 220uF/25V. They are larger in size but still fit and the monitor is happy with them – most importantly.
Thanks very much for taking the time for making this video! I was able to fix my monitor following your instructions.
Could this be the problem with my Dell monitor, they just keep blinking white after 1 second and buttons don't respond.
# 473 here…. thank you for the video sir… i replaced what seem to be the same problem with the same monitor and yeeeessss its working now!!!
You sir saved my monitor today. Thank you!
Did the caps you installed have any special specifications like low ESR? Will any garden variety 100uf 25v 105 centigrade cap do? What do all the extra marking on the OEM caps mean? Where did you purchase them?
Great video, I was able to repair my old monitor for the price of $2, which was the cost of four new capacitors! Thanks
Worked for me!, thanks
Hi, I have question that doesn't directly apply to this video, but you probably know the answer. It's about those backlight CCFL lamps that plug into the inverter board. The Dell in this video conveniently uses only one plug for each lamp, but usually there is a set of 2 plugs per lamp, each having 2 wires that differ in color from the other plug. It visually looks something like this:
=blue&black wires (top lamp)
=pink&white wires (top lamp)
=blue&black wires (bottom lamp)
=pink&white wires (bottom lamp)
in that order for this example.
The problem is it's easy to mix up the order if I forget to note their positions. It's obvious which lamp set plugs into the top or bottom of the board, but within that lamp set there's no way to tell which color set goes where. I could put pink&white then blue&black instead of the original order. Does this matter? As long as both top lamp plugs go in the top inverter board sockets is it okay to switch them around?
Maybe this was the problem with your one screen that worked:
I have one of these exact models, given to me because the screen won't respond after coming out of power save mode. Otherwise the screen works fine. But, when it enters power save mode and the LED indicator turns yellow, if I leave it like that for more than a couple minutes and try to wake it up the LED turns blue and quickly blinks off and on once, then the blue LED stays on but the buttons are totally unresponsive with no screen image. It has to be unplugged from the mains and replugged to start working again. If it's in power save for less than a minute it wakes up okay. I don't have a cap tester, but if I need to remove the caps to test them I may as well replace them.
What do you think?
Edit: I tried it again, this time the blue LED quickly blinked off then on once like above, but showed the Dell logo (that always appears when you first power it on) and froze there. Trying again I see it usually shows the logo briefly, turns black and freezes. This indicates that the screen is actually powering off then on when coming out of power save and causing a conflict with the standby status. Also, when I unplug the screen I need to keep it unplugged from the mains for at least 10 seconds, sometimes longer. Plugged back in too soon and the problem resumes. After several tests the screen turned itself off and froze with the LED blue, this time without entering power save mode.
