Hi,

There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.

Thanks

Hi,
KDL-26S2000 belongs to WAX2 chassis and 3 times standby light blinking shows following error:
DC_ALERT1 as it is shown in service manual.

Following voltage has some problem or missing towards trident chip on main board (trident chip is main processor)

(D3.3V/ D2.5V/ D1.8V)


I'm not sure about your expertise, so in simple terms, replace main board of tv to get it fixed.
Let me know if you have additional question.
Thanks.

There may be no horizontal ouput, Check C515 & 516 and the jungle IC, IC206.

Hope that helps
