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 K55A-1 képcsőcsere után geometria-beállítási gondok--megoldva
Sziasztok! 100Hz-es Plano -ról van szó. Eredetileg A68 QCP Samsung cső volt benne, most Philips A68 ERF182X került a helyére. A függőleges méret minimumra véve is túl nagy, gondolom az R304, 307- et kell növelni. A nagyobb gond, hogy az E-W korrekció is kevés, mivel a kép szélei homorúak és a szervízmenüben nem tudok annyit állítani hogy jó legyen. A rajzon nem látok táblázatot a képcső típusonkénti alkatrész-értékekről :-? Minden segítséget köszönettel fogadok. Megoldás: C415=3n , C423=1uF/400V , R304=1,2ohm és R307=1,5ohm
