Re: sony kdl32bx300 no picture, no backlight, no audio just green power light
Standby voltage is steady all the time. When I disconnect main board from PS board I got this steady readings:
STDBY 3,3V
AC DET.OFF 3,3V
POWER ON -2,1V(negative)
BL ERR 1,8V
No green power light.
Also noticed beneath PS board that one chip resistor 104 is melted. So probably
PS board is bad and also thinking main board because there is no BL ON voltage present just BL ERR.

sony kdl32bx300 no picture, no backlight, no audio just green power light
Hi, I have sony bravia kdl32bx300. No picture, no backlight, no audio, just green power light which blinks once every 30 sec with clicking sound.
I have measured voltage on ps connector and main board connector and they are all ok except BL-ON, no voltage at all. I also noticed when green power light blinks all voltages drop down to zero and then rise again every time. Remote not responding. Is it PS board or main board problem? Any help would be greatly appreciated -
