Dear friends.:
I have monitor with horizontal problem, after check a see a two transistors with problem. Q407= 2SJ449 y Q508= 2SC5047. I check all semiconductors again and change the transistors parts. After turn on monitor , both transistors again fail.
Please can you help me.?

So thanks again.
Best Regards.

Tengo un monitor al cual luego de examinarle, encontre dos transistores en corto, luego de cambiarlos nuevamente se queman los mismos.
Se tratan del Q407 = 2SJ449 y del Q508 = 2SC5047.
Revise todos los diodos y transistores relacionados y no puedo dar con la falla. Si bien el monitor es IBM P202, FCCID = AK8GDM500PS, el chasis es Sony = GDM500PS.
Por favor si alguien tuvo experiencia en esta falla.
Gracias. |
