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 RU-vid videos that cover that topic.
Correction: In the video C704 and C709 were identified as the problem. It should be C704 and C707.
