Installing a new volume / power / LED flash ribbon question...

Hi Guys,

My LED flashlight is acting up so I'm thinking I need to replace the whole volume / power / LED flash ribbon.

As it's a big job, I've just tried connecting the new ribbon to the motherboard to test everything - it's not a repair I wanna make to find out something doesn't work on the ribbon!

I've tried 2 ribbons (from the same seller) and everything appears to work except the LED flash only stays on for between 5 - 20 seconds and then auto switches itself off... When I go back in to the Control Center the flashlight is showing as still activated. When I turn it off/on again it stays lit for a short time - around 5 seconds then powers off again.

I've tried the ribbons on two phones and the result is the same on both.

Are these faulty ribbons or do they need to be in-situ in the phone for the LED to stay lit when activated? Just wondering if something needs grounding etc.

I appreciate any help!

Thanks,

M

did you check the pins on the motherboard for damage?

Pins look good on the board...

I just need to know whether the flashlight stays lit beyond 30 seconds when it's not fully in situ - in other words, when it's just connected to the board.

As I say, I've tested two suspect ribbons in two phones and all four instances are the same. The seller did point out he'd sold 50+ ribbons without incident so I'm inclined to go with what he's saying... Just don't want to do THAT repair to find out the ribbons are bad.

Suppose I could order several more from other sellers just to be sure, but was hoping to get an answer here...

I just checked mine and it stays on way longer than a minute. My guess is that it would stay on until the battery discharged. So, why does yours turn off? My hunch is that your LED is bad. As it heats up, the LED fails and turns off. I'd look to replace that part next.

Thanks for the reply! I just want to confirm the ribbon was not fixed into place (in the housing) it was just connected to the motherboard. The guy I bought the ribbon off has sold 50+ on ebay and his feedback is good, so I'm assuming the ribbons are good too... unless folks haven't needed to use the LED flash.

Is your ribbon fixed in the phone or loosely connected to the board?

Thanks
