Philips 26PFL3403S / 60 no picture, sound
Hello everyone!I have previously repaired this veteran TV, I was just lucky - on your forum a few years ago I received a very
accurate tip for replacing RB5. Here I also downloaded the schematics for the TCM1.0E LA chassis.
The screen does not light up, so I decided to immediately look at the inverter connector: on five wires from the power supply, normally 24 V and several "case" wires come from the power supply. Two control signals come from the Small Signal Board: Select (I have 4.5 V here) and DIM (I have 2 V). Unfortunately, I do not know what voltages of these signals should actually be, but I suspect that the inverter does not receive a normal enable signal and is simply blocked. It is also annoying that the TV has an inverter vit71023.53, and I could not find its circuit. The documents downloaded for TCM1.0E LA show a completely different diagram.
I will be very grateful for any help. the TV belongs to my elderly father and does not want to buy a new TV set
I hope only for your help.
