Problem

[Dnu318]

I have had a home theater system hooked up for over a year and it worked just fine. Suddenly last weekend tge picture goes out but I still have sound.

I have tried different cables. I have tried other applications of tge receiver: I plugged in my phone to get xm. No problem. I used to CD player: no problem. So I know it's not the reciever.

I plugged the fios box directly into the tv: no problem. I ran my blu ray directly from tge tv no problem.

So now I played around with cables. I can get video and audio but it's not passing through the home theater speakers. If I turn the receiver off, I can still get both video and audio.

I have a Yamaha 575 receiver, a Samsung 40EH5300.

Thanks for any help or advice.

So nothing changed for a year then this out of the blue? Usually hdmi handshake issues are more immediate/frequent IME. Try running a full reset on the receiver? Turning on the tv on first, then receiver, then source might help (i.e. starting with the sink and work your way backwards thru the chain). Is it all hdmi other than the cd player?

Definitely go through a reset of the Yamaha receiver and then see if you are able to get anything out of it.

You should get on-screen menus and such for setup. Follow the manual to go through the process. It would concern me a great deal if you don't get any on-screen menus at all from the Yamaha.

Often I would point at cabling, but the TV itself is a lower resolution 1080p model, which is good as it typically means cabling isn't going to be the problem.

I'm not sure if you connected your receiver to a network at any point, but it may be worth doing so and updating the firmware if it hasn't been updated since purchase as this may resolve the issues you have experienced.

My biggest concern may be that internal video processing could have gone bad. So, that specific chip that processes HDMI for output has failed. You still get pass through HDMI, which means that portion isn't bad, but the part that does normal processing and allows volume levels to appear on screen and overlays menus has gone bad, which all the video passes through when the receiver is on... could be bad. So, video doesn't work.

Considering the age of the Yamaha receiver, it is possible that it is just getting to be on it's last legs. This isn't really common to have a receiver fail in under 10 years, but at 7+ years in age, it's not uncommon either. I had two of my clients lose their 10 year old Denon receivers this past year. Both performed flawlessly for a decade, but eventually this stuff all wears out.
