Question Edifier r1280db Turning off and changing channels on their own at random intervals.

[danyuzunov]

So as the title suggests I own a pear of Edifier R1280db bookshelf speakers which are turning off and changing channels on their own at random interval and also sometimes get stuck in a cycle where they just keep doing random things. I opened them and found out that one side of the connector below is broken so I hot glued it in place, didn't work. Another thing that I found out is that sometimes even a light tap on them or at the desk makes them turn off when at another times even a harder punch on the top of the active one does nothing! That happends with all connections and bluetooth and on different power outlets so I am 100% sure the problem comes from them! I have taken the active one completely apart and have not found any other obvious issues aside from the already mentioned connector! Any ideas as to what the problem might be?
Also, HERE is a video of the previously mentioned cycles of random things.
Let's add turnning on randomly and connecting to my phone through bluetooth to the list

Having glued the plastic connector into place does not necessarily ensure a solution.

Certainly worth a try to secure the plastic connector into place.

Overall, because the problem continued the the implication is that some current conducting trace or solder joint/component remains loose and free to move. Even a tiny bit of movement is all that is needed.

Expansion/contraction and vibrations (taps) may randomly combine causing movenment and thus making or breaking connectivity.

May be difficult to locate the bad connection and even more difficult to fix it.

No harm in trying but keep in mind that further repair attempts should be done with the understanding that the speaker is expendable.

yeah but it seems that even without being in a room with them still makes them turn off or switch channels and after further testing it seems that to more they are being used the worse it gets! To me it seems like either overheating or bad psu as a whole because I don't see how that connector will cause any of those other one! I am absolutely certain that it is NOT the connector's fault!
I started writing this like 25 mins ago and since then I tried running them with the board in my hand and it doesn't see

Wondering about the controller.....

Wondering about the controller.....

might be. At full volume they stop near instantly....(most of the time)

imma get the psu out again first, check everything there is to check on it and I will replace everything on it if I don't find any particular part to be wrong with it

My R1850DB has just started to go into standby by itself. Works for 10-30min, then goes into standby.. then it's a pain to get it back on (1-2mins) then it'll work for a bit longer.

They're out of warranty by just over a month. Sigh.
