Looks like one red wire is not soldered. Does it go from the battery? And looks like it has to be soldered right near the corner of the PCB.

You need a voltmeter to go a little bit further.

Solder the wire back, connect the battery, insert in-out jacks, and trace the power voltage following wires from the battery to the board. Check if you connected properly input and output jacks.

Power switch in pedals very often is located inside of one of jack sockets, so when you connect your pedal, it is powered on; when you disconnect, it is off.

Check if power (9V) goes from the barrety to the board, a first.

Try a new battery, it must be 9V. Also, check if a power switch "supposedly on one of jack sockets) is on when you plug your guitar and amp jacks.

Did you check voltages after recharging your battery?

If the voltage drops down to the 3 volt either your battery is dead, or you must see some smoke going from your PCB.
