Hi,
I'm getting my VHD system setup and I've run into a bit of a problem. I'm pretty sure it's something to do with my Yamaha receiver. Let me explain.

I feed the A/V from the Victor VHD into the line input of my Yamaha RX-A2020 receiver. The receiver up-scales to 1080p and outputs to a 55" Sony LDC TV.

During playback, the picture will go black and after a second comes back on. It's not an issue with the disc, because it happens on all discs, and even happens on 2 different CED players. I know the issue isn't with the TV, because I just upgraded the TV and it does it on both. I don't have this issue when I run any LaserDisc player through the same input. If I pass the VHD signal through an external up-scaler (the crappy $20 jobs from Amazon), the "blinking" stops, but it stretches the picture out to 16x9 (and sometimes not evenly).

Any suggestions on a video processor or up-scaler that will resolve my issue AND maintain the 4:3 aspect ratio?

BTW, I can't simply run the Composite video to the TV... My new Sony only has HDMI inputs.

My guess is the VHD sync is too crappy for your receiver to lock onto it. You you could run it through another device, like the pass through on a DVD recorder or a better than average VCR (anything with a time base corrrector and/or dropout compensation) and see if it works better that way.

Btw, my 2017 Sony Bravia does a wonderful job with composite. Is your TV more high end than mine or more low end? Or maybe 2017 was the last year? I’d never buy an HDMI-only TV if I was the sort of person who collected junky old formats like this.

I was thinking the same thing. My 2018 Bravia XBR-55X900F, I just looked again and it DOES have a composite video in. But it's on a 1/8" plug, not an RCA jack. Pulling out my handy-dandy converter cable, and ... Perfectly stable video. I tried adding video processing so the receiver is doing the up-scaling, but I can't seem to keep it at 4:3, and even worse, it add a fraction of a second of delay to the video and THAT makes me nuts.

Bottom line is I think I'll still need to find an upscaler to fix the problem.

With all your analog devices, you should consider the Lumagen Radiance 2144 while still available.

Your TV doesn't let you change the aspect ratio manually?

That’s for sure a choice on my 2017 Bravia which also has an 1/8” TRS combo jack for all SD video.

I have *zero* issue with LD on this TV and I don’t use any external stuff. It looks incredible. LD is a way better format than VHD though.

If the TV is fed a 1080p (or 720p) signal, the aspect controls on the TV drop the option for "Normal" to display 4:3 images with borders.

Then don’t feed it a 1080p signal. Just plug it in. Your receiver may do a better job on composite video than current gen Sony Bravia tech but I doubt it. Just because something is external doesn’t mean it’s better.

Clearly you've not read the thread. When I feed the raw signal into my receiver, I get random video blanking. I've tried adding video processing with the receiver, which corrects the blanking problem, but then the video lags behind the audio by 250ms or so.
