Morning everyone
i have a problem with my printer epson tx121, when i plug in the Cable power(AC), the power supply will sound off the beep continuously and the printer won't turn on, i has been checked the power supply with plug into the other epson printer that same vendor and printer with my problem's printer and the power supply run normally, so i guess the main problem is on the motherboard.
the question, whether the diode on motherboard affect the beep? and how to check the diode to prove that short or not?
deeply thanks for your reply
