Re: lcd tv SAMSUNG LE40R71B not work ,relay clicking
On the CNM801 coupler, pin 2, the voltage STB = 6.5V, see schematic diagram...,
anyway solved by replacing the eeprom 24C32 (IC903) with empty memory (FF). Thanks!

Re: lcd tv SAMSUNG LE40R71B not work ,relay clicking
Thanks for the reply, I reset, but nothing has changed. When it normally works the voltages are the ones written on the board and when it does not go (the relay click) the only correct voltage is STB (stand by) = 6.44VLeave a comment:

lcd tv SAMSUNG LE40R71B not work ,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 optocouplePCS802, 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... -

led tv SAMSUNG UE40D5003 power supply+driver LED : BN44-00473A -not turn on
I have this tv with this problem: at start-up, the St.By LED flashes twice, after which it stays in St.By, sometimes the LED flashes twice in a cycle of 5 time. At the start, for moment,is present the tensions PFC = 390V, voltages of 5,2V, 12,7V and voltage for led driver, after that this tensions fall in 0. I replaced ICP801S = SPC7011F, ICM801 = FSFR1700XSL, the electrolytes caps beside these two integrated and PC801S, PC802S, PC803S optocouplers, I redo the soldering, including the smd components, "cold" measurements on components. Only the voltage St.By = 5,2V, the rest, no change.... -

Re: lcd tv TOSHIBA 32AV500P inverter board MPF3002 (PCPF0207 77C)
It can not be, because it is not a simple inverter, and the power source (with PFC) for the inverter is also included Thanks!Leave a comment:

lcd tv TOSHIBA 32AV500P inverter board MPF3002 (PCPF0207 77C)
I have this problem TV on the inverter module with the above code. It accepts the BL ON command voltage, but so much. Initial was defective Q50 = 2SK2837, after replacing it normally worked, then stopped with the current sound without the backlight . It is equipped with BD9766FV, FA5501A, 2904H212, RM601. The plate is quite "bushy", difficult to follow without a schematic. On somewhere I saw it would be equivalent to DPS-165GP (JQ10003), but it does not look like.... -
