Problematic power circuit that i have no idea what is wrong

Heres my power circuit

I've already fabricated the pcb and started soldering all the components together
Checked continuity, all the connections on my PCB are connected properly

But the problem is that the DC to DC boost converter is not out puting any voltage on the output side nor receiving any voltage on the input side

When i probe the tp4056 on the OUT+ and OUT- pads with my multimeter, they output the battery voltage, 3.7 volts but when i probe the input of the DC to DC boost converter, it shows 0 volts for some reason, then, when i probe OUT- and the negative pad of the DC to DC boost converter on the input side, it shows 3.7 volts, but then when i do OUT+ and the positive pad of the DC to DC boost converter the voltage is 0 (I'd like to clearly the OUT+ and OUT- mentioned here is the ones on the TP4056)

I am frustrated on why nothing works and what to change, this is very hard :frowning:

Edit: The MT3608 is the dc to dc boost converter

Take the battery out and check for continuity. Do you have continuity through the switch? Maybe it's mis-connected somehow. Maybe there's a bad solder joint.

If you get your PCB design tool out you can check connections with that and your PCB design .
It’s not uncommon to miss tracks off ( I have the Tee shirt )

As i stated in my post, I've checked for continuity and everything (seems) to be correct, including the switch individually, all seems fine, all continuity checks are done without the battery connected

I use EasyEDA actually, and i use it's DRC thingy to check my connections, I've made sure the incomplete connection thing was 0 before i send it out for fabrication, so it (probably) shouldn't be a problem

I don't understand the pinout of your TP4056. Are you using a module of some kind? Where is the charging power input? Where is the programming current resistor? This is what the data sheet shows for the chip itself:

Oh yea i should've mentioned im using a module not just the chip

Ok, then you probably have the module that has protection built in (it has a DW01 chip in addition to the TP4056). The DW01 may not allow the system to turn on when a battery is first connected. I think that's to save battery power during shipping. Anyway, try connecting the charging power to the module input, and see if that turns it on. You only have to do that once unless you replace the battery at some point. If that doesn't work, then I don't know.

Ok apologies because somehow i missed checking the continuity on OUT- and the negative pad of the mt3608, they were missing continuity, probably a bad solder joint

But its all working correctly now with them both connected
