Led pisca 4x e volta pra stand by | A negative voltage of 12v comes out at the power supply and goes to tcom. after the fuse (f8) tsound are two coils (b31 and b32) and immediately after an 8-terminal switch (trans. q27) | It was not "switching" the -12v, close it directly to confirm the defect (pin1 with pin8). This is just a guide to testing, the correct thing to do and changing the tcom card. | |
