Sony HCD-GTZ3I - No go.

(1/1)

Turnip:
Hi folks,

Have one in where when plugged in, relay clicks and lights flash. If any action button is pressed it cuts totally 'till plugged in again.

Suspected problems with the STK433-300 three channel 240 watt output module, but can't find any actual shorts or burned bits.

Wonder if it's a known issue - Thanks - Chris.

PS - Have the manual from the usual helpful free site.
