TTGO t-beam issue

have two TTGO T-beam… one with GPS that work fine but when i try to turn it on just by connect 5V to vcc without USB it seem to stay in sleep mode… have to push te power button or connect the usb cable to start the code.

the other one, i can’t start the GPS…i remember i have to send a code to activate it, and think i did i right, but still no connection but the red LED on the NEO6 is blinking…
