Elromlot szegénynek a keresője és nemtaláltam hozzá alkatrész pedig magyar gyártmányú, szóval ha valaki rendelkezik a tipus Kapcs. Rajzával Örülnék ha segítene. Előre is kössssz..!
Üdv. mindenkinek!
Tudja e valaki,hogy a SAMSUNG UE19C4000P ( táp:BN44-00345A ) tipusú Tv nél a primer köri tápfesznek 400V –nak kell e lennie.
üdv.
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!
I attach the power supply+ inverter schematic model BN44-00134A
