my problem started a while after the update to 246. The machine lost a lot of battery even when switched off and then at some point did not turn on at all (high pitched noise from the speaker no matter in which position the on/off switch was). Therefore, I thought that the DSP board is defective. I also had a spare connecter-board and tried that - but that didn’t solve the problem.
After I unplugged the battery and plugged it back in - at least it started up again.
It still makes that high pitched noise when charging - depending on cable and power supply in different frequency. Now I’m not quite sure if it’s just the battery failing, the DSP or something else. I rolled back to 245 but the battery drainage is still present (battery all gone after 1 1/2 days turned off).
I you have any experience with that as of which component could be failing, it would help me a lot since I can tackle the issue more precise. I tried factory reset, firmware rollback, different cables, chargers etc…
Hey there,
thanks - I ordered a third party one and will report once it’s replaced. My greatest fear is that there is something wrong with the DSP that draining power even when turned off
Does anybody know the battery connecter type used on the OP1? I think it’s a 2 pin SH 1,25mm Micro JST?
Alright - thanks a lot!
Replaced the battery but it’s still losing charge when turned off. Like the charge is all gone after 2 days being turned off. So connector-board and battery weren’t the problems. My guess now is that the DSP is faulty. Is there someone on this forum who has experience with the circuit of the board to make a guess which part of the DSP could be damaged? I want to avoid buying a new DSP Board for a lot of money when all that needs to be done is replace a capacitor or a resistor…
I’m having the same issue Got my OP1 in early 2017, so its managed 6 years of useful and creative life, but seems its sadly heading towards retirement and obsolesence
Hey there!
I’m not willing not give up yet
The wonderful @jon helped me so I could replace one of the capacitators but that didn’t solve it. I found a similar problem with the battery draining while turned off on a ZOOM device and their problem was a bad cap. So yeah - Jon also suggested that it could be a damaged flex cable and I’ve ordered one but it hasn’t arrived yet. What bums me out is that it’s impossible to obtain my specific dsp (white - REV 2) from the the repair shop here in europe.
But good luck on your journey - maybe you can find a solution!
Replaced the ConnectorBoard - the Cap (as obvious) and the battery. I bought it used - so can’t really tell how old it is. But it worked for at least half a year
From the pictures the display looks matte but I’m not sure if it does due to the picture being out of focus on that area, please can you confirm it’s a matte screen?
I’m asking because from my research there are several revisions (at least 4) each with it’s own OLED display and connector to the DSP board, as far as I know there is only one revision with a matte display (which should be the latest).
As for the high pitched whine, if it’s happening while charging, that’s normal, it’s a feature to prevent pushing too much current on a drained battery which could very likely reduce its lifespan.
Basically if you have a drained battery the first hour of charging (more or less) should happen very slowly, then the high pitched whine should stop and the battery should start charge more rapidly.
I assume that you have already tried to reset the battery indicator an let your OP-1 charge for 3-4 hours.
Also I see that you’ve replaced the battery, I’ve heard stories of people frying the DSP board by cutting both wires on the connected battery and causing a short, battery should always be disconnected first and then the wires cut one at a time. (can you confirm this didn’t happen to you?).
Is your replacement battery an aftermarket battery?
Have you double checked the correct polarity of the battery?
(very often those aftermarked batteries have polarity inverted)
Have you reused the old battery connector? In any case triple check the connector pins with a magnifying glass to see if there’s anything wrong there.
Thanks for responding. So - the battery wasn’t attached when I replaced the connector. And I didn’t cut the both wires at once. One after the other. So that didn’t fried the board.
The machine operates exactly the same after replacing the battery.
Yeah - I used the old connector and wired up the red to the red cable and the black to the black cable.
It’s not the original battery from te, but the specs are almost the same (except physical size).
I think if the polarity would be wrong, it wouldn’t operate as it does (normally except for the massive battery drain). But I’ll check it again tonight. I’ll take a close look at the connector pins too! Thanks for the suggestions
What I meant is that those aftermarket batteries sometimes have inverted colors on the wires, it is always best to check the polarity before installing those batteries (it is also stated in most of this batteries description/manual).
Please don’t forget to check the polarity of the battery before looking at the pins.
You could very likely be charging and running your new battery in reverse, in which case I’ll recommend to dispose that battery which is now ruined and replace it with a brand new one (after assuring the right polarity).
Maybe this isn’t the cause of the issue but it’s worth checking before proceeding with further investigation.
Hi , just came acroos this tread - i have a similair problem.
Got OP-1 with old original battery that didnt hold a cgharge , replaced the battery with aftermarket one - OP worked really well for couple of month.
Than after bein idle for 4 months its started showing similar symtomps: Fast battery drain while being turned off 2/3 days. It had a high pitched noise couple of times while bein on or charged but than the noise stopped.
Now its not charging till full only to 3 dots out of 5 .
What could be causing the problem of a battery drain - anyone?
thanks in advance for any ideas
the only thing i can offer help-wise is definitely make sure to verify the battery life. my op1 goes no higher than 3-4 dots, and after 1 hour goes to just 1 blinky light, and then proceeds to work flawlessly with heavy use for at least 12-14 more hours. so don’t trust the light. verify it empirically.
Thanks for reply djCuvcuv !
i tried a hard reset from the boot screen that wiped all user presets and sounds .
and after restart the battery level showed as Maximum 5 dots .. for some reason?
ive used the OP1 for some minutes and turned off .
Started the OP1 in the morning ..about 12 hours later and battery level shows 3 dots again .. so there is a drain happening .. i am puzzled ?
tried reinstall the OS but that didnt change the battery drain still 3 dots.
Its a new battery installed it only a year ago and barely used.
still looking for ideas on what is causing the drain
thanks in advance
peace
Jazz
hey no problem! happy to try to help. so my main point is do not trust the dots. the dots changing may not be indicative of actual battery drain. my dots are not reliable and this is common ive heard, but the battery will still often last or even exceed the spec. like i said my op1 goes down to just 1 light after an hour and then proceeds to work great for like 14 hrs or more with heavy use.
this is what i think you should do:
charge it overnight using a normal iPhone or 5v block or laptop
dont even bother looking at the light
use the op-1 normally and keep a notepad of exactly how long you use it for each session
do not charge it at all until it literally dies in the middle of your session (screen goes black)
add up the total time the battery lasted since that first overnight charge
again, do not look at the dots.
if after this your device has only given you anything less than 6-8 hours, id say you have a waning battery. if it lasts anything over 10 hours in total, id say your device is working as expected.
