lcd tv SAMSUNG LE40R71B relay clicking
I have this TV equipped with the source BN44-00134A.Tv does not start, it is heard how the relay is continuously coupling and disconnecting. The stable voltage drop is STB = 6.5V, P-ON / OFF varies between 0.2-2.5V in normal operation = 2.6V) PFC between 360-385V (when going is 382V). All electrolytes, secondary-primary, have been changed, except the 220uF / 450V which is ok. In this state, if measure the voltage on the pins 1-2 to optocoupler PCS802, the relay stay connect and tv work normally . I have replaced the PCS802,801, the ICS 802 (KIA431), the QP803, the QS801, the QS802 checked. If I stop it(unplugged) and I restart the tv in a few minutes, it works normally, if I leave it a little longer, the defect returns. Any suggestion is welcome, I do not think it would be the problem with the mainboard. Thank you!

SAMSUNG KS3
Sziasztok! Van kettő KS3 elktronikám. Egyik 100 a másik 50 HZ-es. Az 50-es villámcsapott, tuner és VDP3120c3 cserélve a 100-as LA7845 cserés volt. Jelenleg mindkettőn van kép és hang, viszont ugyanazt a hibát produkálják. A kép hordós, OSD függőlegesen fut. A 100 HZ-es panelba egy üzemképes készülékből már átraktam a procit, opció IC-t, digi-t. Tápok jók, OSD továbbra is fut. Help! (A korrektor IC-t és tranyót is cseréltem újra.) Köszönettel, TO.
