HITACHI PD9700 HDMI BOARD

[mihaiwinterlik]

Model HITACHI PD9700. HDMI board was changed. No sound. No possibility to change the source definition.  Definition blocked only for: 720i; 720p; 1080i all 60 Hz. I have changed second time the HDMI board and the problem persists.
With old board (one HDMI input burned) I have sound and I can change the source definition.
All replacement parts were new, delivered directly by Hitachi media Europe. How can I solve this problem?
Manny thanks!.
