Good morning,
Samsung UA32F4000AR Not Switching on. Red standby led constantly lit when plugged in, wont respond to P function control or remote.
Voltages measured on MAIN pcb plug CN201 (legend on PSU pcb plug CNM803) Photos 1&2
Pin marked voltage measured voltage
1) 13v 13.4v
2) PWM_Dim 0v
3) 13v 13.4v
4) ECO_On/Off 13.4v
5) Vamp 13.4v
6) BLU On/Off 0v
7) Vamp 13.4v
8) Gnd 0v
9) Gnd 0v
10) Gnd 0v
11) B5 5.4v
12) A5 5.4v
13) B5 5.4v
14) Power_On/ Off 3.4v
IC901 Winbond 25Q128FVSG (MAIN pcb)
1) /CS 0v
2) DO(IO1) 3.4v
3) /WP (IO2) 0v
4) Gnd 0v
5) DI (IO0) 0v
6) CLK 0v
7) /Hold or /Reset 3.4v
8) Vcc 3.4v
I have repaired two of these sets before by just replacing the MAIN pcb, Could the MAIN pcb be repaired rather than just replacing it?
Please if anybody could steer me in the right direction
