Marantz SR4003 AVR HDMI board issue, seeking for help

[aliougm]

I have problem with my AVR(Marantz SR4003) HDMI board issue. I connect to my TV but screen color distorted,see attached picture.

Connection as below:
Set-top box HDMI output >AVR 3 HDMI input/one HDMI output>HDTV HDMI port
If I bypassed AVR then HDTV screen color be good.

I take out HDMI board from AVR and check services manual the schematic shown the HDMI signals path:
3 HDMI input port > SIL9185 chip(HDMI switch) > SIL9033 chip(HDMI receiver) > SIL9030 chip(HDMI transmitter) > HDMI output port

I replaced all of these three chips but no change. Power to chip 1.8Vand 3.3V is fine. I have no idea what the next I can do.

Anybody has experience to deal with such problem, please advice, thanks!
