Dell E177fpv Caps and Ribbon Cable

[mandacat]

Dell E177fpv ...

The monitor would come on but go off quickly. The two 470ufd 25vdc caps in the inverter circuit were bad, but I had to remove them to test as, in circuit, the ESR meter showed good, probably due to a parallel circuit.

Anyway, the monitor now works great, but I could not figure out how to remove the Ribbon Cable from the LCD side. I finally wound up removing it from the video board side, which was a pain. I must have wasted an hour between trying to figure out how the remove it from the panel side and then replacing it back on the video board.

Although I've finished the repair, I am very curious as to how to remove that cable from the panel side. It has what looks like spring clips, but I can't see how they release that cable. Any ideas ??

Thanks

Sorry about not snapping pics when I had it apart. I should have thought of that before I returned it to the owner. If it helps others, the two bad caps are CrapXon 470ufd @25vdc electrolytics closest to the transformer nearest the edge of the power supply board. They're a good distance from any of ther others and will test good - in circuit - with an ESR meter. They are not in parallel !! I replaced them with 680ufd @ 25vdc Nichicon's which were taller and left extra lead so I could bend them over slightly to fit in the same head room.

As far as the ribbon cable, unless someone has run across that type of ribbon cable connector used in models like it (which I haven't), it probably would be hard to visualize without pictures.

Again - sorry for the omission

Managed to find a shot of the subject E177FPv board here in the forum. I edited it, indicating the Bad Caps.

Thanks to "johnboy183" for posting it.
