For those using extended battery wo cover..means pin can't ground.
Yep
For those using extended battery wo cover..means pin can't ground.
There is a golden pin soldered into the player's board. Its purpose is to ground the metal battery cover. There is a hole in the back panel for the pin to go through. But, the back panel has a conductive tape inside, for electrical contact between the battery holder and the battery cover. In my DX90, the tape prevented the pin to go through the hole.
But if the pin touches the conductive tape, and the tape touches the metal battery cover, the pin is grounded through the conductive tape to the metal battery cover, right?
I cut the conductive tape , but the pin, that is spring loaded, doesn't come out enough to touch the metal battery cover, it just sits not flush to the back panel. So what do I do now? uzzled
I confirm that on my device the golden pin doesn't come out from the hole enough to touch the metal battery cover, see pic. What to do?
But if the pin touches the conductive tape, and the tape touches the metal battery cover, the pin is grounded through the conductive tape to the metal battery cover, right?
I've had a look at mine too and it's also covered. I would have thought the same, the pin touches the tape, the tape touches the case...grounded?
I think the answer is clear once you remove the back plastic panel: the tape is black on the downside, I think it is not conductive on this part, while the silver upper part is conductive. Since the pin pushes on the black part, it is not grounded, but isolated.
good day,
i've read the postings containing tips about bringing the "golden pin" up to get the backplate contact.
I DID NOT recommend to do this with a nail/pin penetrating the tape closed hole to lift the golden pin.
( oh my god this is not ment sexual, LOL )
You could damage your DX90 inside, if tossing the nail deep down into the hole and if conductive tape
falls into the unit it could fast give a electrical short.
EASIER and LESS DANGEROUS is:
1. Remove the "Battery Backplate" by sliding it up
2. Remove the Battery
3. Remove ALL little > 7 < screws as shown. ( using the right fine screwdriver )
4. Remove the "closed hole plastic plate" by sliding it down. ( easy sliding like the backplate )
5. Flip this plate to see the conductive tape at the back. ( you will notice that there is a small hole for the pin already,
but not at the right place, uhhg manufacture... )
6. Take your favourite rasor / med / bounty knife to cut a fine square of tape away.
You have to clean cut ROUND the "OVAL HOLE" at the right side as shown.
7. Remove the inner tape rest to uncover the hole. Take some breath to spray out rests of conductive tape.
8. Reassemble the unit : slide Plastic Plate back to place, fasten ALL screws, insert the Battery,
slide the Backplate at it's place.
The is no really need to scratch the Battery Backplate for having contact. Sliding the Battery Cover two or
three times with a outstanding golden pin does the same scratchin.
Damn, i am sorry i wanted to upload some pictures but my account is limited at first postings.
Maybe i could upload them later to finish this how to.
