Samsung No HDMI Inputs

[trammsrvt]

The HDMI ports all failed on my Samsung UN46B000VFXZA but the RCAs work. I verified the source and cables work and tried all of the reset fixes, etc. I believe it's the main board #BN94-02657D and unfortunately, I can't find this board online.

I'm investigating whether I can find and replace the broken component. Does anyone know which components likely the cause of the HDMI failure?

Any help is appreciated.

Its the 144 pin HDMI switch IC.

You can find it easily, by following the traces back from each HDMI port. They all collect on to one single IC. Does that IC get hot?

Thanks for the help, I found the IC. It's a small fine pitch produced by Silicon Image. Not sure trying to find a replacement is very practical but I'm going to see what I can find.
