Has anybody had any experience with the following issue? The two HDMI ports are dead and the screen just shows no signal when a good source is connected HDMI. I can get a signal in AV but not HDMI. I have already tried the tv reset. Is the firmware update-able on this model? Is there a service menu I can get into?

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... -
Following a power surge, the HDMI ports on a UE65MU7003U no longer work, no matter the port or the source - it shows No Signal.
The other functions work well (eg Netflix app, etc.), its just the HDMI ports.
Is the BN41-02568B board salvageable? Any leads before I open the heatsink cover? board replacement?... -
Got my butt kicked by windows 10 and intel last week.
I have an HDMI switch and splitter setup for an AV rig (church) that I was trying to use the windows 10 half of my Lenovo T440s with. However, the audio will not work; HDMI (displayport) audio doesn't show in device manager and Intel's Control Center shows the external display as not supporting audio. Direct connect it to things and (if memory serves) it does work.
Compounding the issue is that I'm forced to use Lenovo's drivers... as the generic intel ones refuse to install as they detect it's a lenovo system... -
Anthem MRX500 - no sound
Dear Electronics Experts:
I have the following problem I am trying to troubleshoot. Unfortunately, I have contacted Anthem themselves and even a local distributer but I am not having much luck. Also, I have scoured the internet and unable to obtain a service manual. The Anthem service rep has also replied that he is unable to provide me with any service documentation. I have performed numerous searches on the internet and cross-referenced a few other AV receiver makers (Denon, Marantz, Onkyo) and found certain similarities to block diagram... -
