Samsung LE26B350F1W

Recommended Posts

Salut,

 

Incerc sa repar un Samsung LE26B350F1W, care in timpul functionarii s-a oprit brusc.

 

Am gasit scurt intre pinii 3-4 CI UM801S = ICE3B0665J si siguranta FM802S = 2A sarita, acestea au fost inlocuite, acum se aprinde led-ul de standby, dar cand apas butonul power clipeste de 4 ori led-ul apoi se stinge, pe display nu apare nimic.

 

Tensiuni CNM802 fara conectare placa logica / cu placa logica.

1.on/off = 0.8V / 0V

2.stby = 5.2V / 5.2V

3.gnd

4.13V(S) = 12.9V/13.2V

5.gnd

6.gnd

7.5.3V = 5.2V / 5.2V

8.5.3V = 5.2V / 5.2V

9.gnd

10.13V(M) = 12.9V / 13.1V

11.13V(M) = 12.9V / 13.1V

12.inverter on/off = 4.7V / 5.1V

13.e-pwm = 5.8V / 2V

14.det_5V = 0V / 0.1V

15.sync = 0V / 0V

16.gnd

 

Sursa model: BN44-00291A
