Today I try to turn on TX1 as usual, power light didn’t come on. HDMI has output and TX1 module seems work fine. NO USB power. Checked schematic and found out that everything on carrier board gets their power from Buck converter on carrier board, not from the actual module.
Checked buck converter, 5V one didn’t work, I took the inductor off and then connect 5V from power supply, everything seems work fine.(3.3V buck converter works!) So it seems like a problem with 5V buck converter and I haven’t figure out the reason.
I want to know if there is a place where I can buy another OEM carrier board, or is there some kind of warranty for the carrier board.
Anyone encountered same problem???
