I dissasmbled my tascam m-106 and im not sure if i put all the screws where they belong and now when ive started it it wont output any sound i can tell it can take inputs cause the overload meter turns read when i cranked my guitar into a input but the VU meters dont move? anyone got any tips to what i should do? and have i ruined the mixer in any way? oh also theres three screws i havent put back on the top frame of the mixer!

yup im a newbie that shouldnt have opened it up in the first place but please be gentle with me
 
“Won’t output any sound….”

From where? Have you tested all inputs and all outputs? It is important to be as specific as you can so your helpers have as complete an information set to work with. Are you unable to to get signal to pass from any input to any and all outputs including the AUX and EFFECT busses and the 4 mix busses?

Is there any meter activity?

How confident are you that you reconnected everything and reconnected it correctly? Did you take pictures beforehand and/or make notes and/or labels to ensure correct reassembly?
 
yes all the outputs are not outputting any sound and the Vu meters won’t budge! no i don’t think i reassembled it correctly! at least I didn’t reassamble the screws correctly! cause the top screws won’t fit only tre fitted the top cover

no meter activity at al! but the OL indicator flashes when i turned up my guitar and played it through channel 1-6

and could it maybe be a grounding issue with all the screws?

No. Grounds for signal are not like the ground with a DC battery. Signal grounding provides shielding. Audio signal is AC voltage. It’s not a loose screw. And 0V reference for the active devices like the opamps is handled by connectors, not screws in the M-106. Did you completely disassemble it? Like how much of a tear-down did you do? If you are not confident you reassembled it correctly, then it’s time to open it up, take the service manual and wiring diagram and start checking your work. And if you’re not confident in your ability to do that then it’s probably time to find a tech and get some help from a professional.
 
i’m confident but i don’t have a service manual i can check!
so maybe something got disconnected is rhe VU meter and monitor mix and outputs connected in someway? because that got screwed of?
 
I would test it in as simple a way as possible.

Thus for now, forget about guitars, mics, speakers and so forth.

Simply connect a cd player, or your cellphone if you have something like Spotify to play music, and have a 1/8" to dual rca cable handy,
to input music into the mixer and see if you can hear it thru headphones at the M-106 headphone jack. CD player instead- just need
rca cables- connect to a channel with stereo input jacks or to two separate channels for left and right stereo and adjust pan pots hard left
and right, or even if you got mono, the main thing is to just start with something uncomplicated to test if you can put music into a channel
and then hear it thru headphones. Once you can establish that it works or it does not, you can proceed from there.
 
Yeah I think the OP is stating they already tested all inputs and can’t get signal to any outputs.
 
It seems like he used his guitar- but its unclear- acoustic with pickup/preamp, electric with amp, mic, or direct in, ????

Thus why I suggested to keep it simple and just use a cd player or cellphone and simply check that music can be detected thru a channel, or all channels
and be heard at the headphone jack. I think its also a good thing to do when a novice wants to get acquainted with how signal routing works whenever they
first acquire a mixer - as opposed to going right into connecting a bunch of instruments & mics and then getting confused, although I can understand the enthusiasm
for wanting to create music and having fun as quickly as possible.
 
Yes I agree, completely. I guess what I was trying to highlight is I think whatever the OP is trying to do now that’s not working was working before with the same setup. I didn’t get the impression it was so much a matter of not knowing how to use the equipment, but rather a change in the functional state of the equipment. I might be wrong. Regardless I agree with your advice from a general perspective, and maybe specifically here if I’m mistaken regarding the profile of the scenario.
