(8) Solder pin no.5 of T100 and check the voltage at pin no. 2.
(9) Unsolder L102, and measure the voltage at pin no. 2.
When the voltage appears: Replace components in order of the tuner, 1C400 and IC200.
(10) Unsolder L103, and measure the voltage at pin no. 2 of T100.
When the voltage appears: Replace IC300
