Re: Dell 1704FP

Thanks for the comments. My replacements are supposedly low ESR based on the datasheet, but they're not Panasonic/Nichicon/Matsushita so no gaurantee. I'm using the monitor for personal use as a secondary backup, so if I run into further issues with caps going out, I will probably replace all of them with high quality caps.



Yep, the originals were Capxon.

I would have replaced all of them if I had the correct values on hand, I just got lucky and had a few of the 1000uF....

I just completed a repair of a 1704FP with bad caps on the power supply. This was a very simple fix, but maybe it will help someone working on the same model in the future.

The only symptom was not powering on when the power button was pressed.

The photos are:
1) Top side of power supply board.
2) Bottom side of power supply board.
3) Top side of power supply board after repair.

5) Working monitor after repair.

The replaced caps are C823, C824, and C825. The originals...

Re: Dell 2407WFPb Monitor - Bad Cap

I have been reading this thread in hopes that I can fix my 2407WFPb monitor.

I have the same problem as the OP and a few others. No power when the button is pressed on the monitor.

The top of the board shows damage to the large cap:
C605 - (To be replaced with EET-UQ2W121BA):


The bottom side of my board shows damage to:
IC651 - (To be replaced with L6561D)
R674 - ???
Q654 - (To be replaced with MMBT3906)



Additionally, I plan to test/replace...
