I have a Sony KV-25X5k while I was watching TV, it turned off . If I press the power button the stand by led keeps blinking 2 times but nothing happens. Can someone help me?

Anyway it seems a FE1 chassis. Year 1998.

Complex fault this , be aware !

CHECK:(MTZ J 5.6B, a 5.6V zener) leaky

and D705, 1SS133T (1N4148) O/C.

check if line output transistor is s/c, if it is also replace line output transformer, do NOT use copy transistor, use genuine ONLY!!! 2 flashes is over current protection
