Tuner may be loading down the data- clock lines unsolder and then power up.
I had several sonys do this.Also check the +15 and -15v line resistors off
the flyback .47 ohm I think.

Subject: [TechAssist] Sony KV-27S22- Power led just blinks
> Greeting,
> This is for another shop: Sony KV27S22/ mfg-1997, when power
is turned on you can hear high voltage come up then shut down, the power led
just blinks continuously, has separate power supply board and all checks ok,
also H.O. transistor is ok, all connections on main board have been
resoldered and double checked H.O. driver transformer, does the power led
blinking continuously mean anything. TIA
