HDMI connection issues just started

[PA-WOODCHUCK]

Samsung - 49" Class Q60 Series QLED 4K UHD Smart Tizen TV purchased 2020

Connected to Yamaha media/stereo.

New here:

1-when turning on I get can't connect/find HDMI source and sometimes turning off/one several times fixes issue.

2-Other times when can't find HDMI source defaults to Samsung-TV

3- nothing has changed with media setup.
Firmware current and have reset TV.

I'm open to suggestions & thanks
