the problem in this tv Samsung model CT20F3 shasis AA41-00625C is that there is osd there is audio but no image there is only black screen, when I upload a bit the screen with delay stripes the image is seen but very little ...
Tests done: ABL voltage I have 125v which I measured in the C812
Eh changed screen or trc.
Eh changed flyback.
Eh changed trc insert since I have an equal of another samsung.
I have filaments ok.
On the flyback pin of the 185v when measuring it on the D812 diode it gives me 85v voltage following the track until the trc connector is the same as the 85v.
In the HEA pin of the fly I imagine that it must be the heater give me tuner mass voltage and red tip in the positive of the C406 in alternating current 4v.
In the jungle pin 49 gives me tension of 1.8v eh read that it must have 3.3v which changes the q201 but remains the same ..
I changed the eeprom of the other Samsung chassis that I have which are similar but nothing.
ps I don't know what to make real friends. I hope you can help me solve this fault.
Greetings to all the fellow friends of Yoreparo.
