It looks like my UMC-200 has a hardware problem. It boots up fine, but there is no audio and the HDMI pass-through is "weak" (for lack of better word).
For audio, it always shows "stereo" on the UMC-200 display and has no sound output at all, regardless of whether I use an HDMI, optical, or even the built-in FM turner as the audio source.
For video, the UMC-200's HDMI output seems to be very weak. When using the cable box as a source, for example, the HDMI handshake with the projector takes 10 or 15 seconds of flashing video to complete the HDMI handshake, if it completes the handshake at all, and even after that the colors on the screen are very far off. As soon as I change the channel on the cable box, the picture goes black and HDMI struggles to handshake again.
Does anybody know what hardware failure could cause the symptoms above?

I did have a problem a couple years ago with the UMC-200 being stuck on the "loading..." menu during the power-on boot-up process -- but I replaced C18 & C19 with upgraded capacitors as documented here -> emotivalounge.proboards.com/thread/41827/umc-infinitive-loading-after-power. I have the upgraded caps, and it is booting up fine, so the new problem seems to be a different issue
