I recently bought a component rca cable ypbpr to hdmi converter for my old pioneer dvd player to my new sharp 4k tv. It is powered by a usb cable.The dvd player menu appears on the screen just fine, but when I play a dvd, the signal drops and I get no picture. The pioneer dvd has component outputs as well as your standard yellow, red and white outputs and is capable of displaying both at the same time. So I can test that the dvd is actually playing by connecting a yellow video out cable to another tv at the same time. So in other words, it is playing. I assume since I can see the dvd menu on the screen ONLY connecting the component/hdmi converter, that it must be working. The converter claims to accept 480i , which my old dvd player is playing at I guess. I've tried many dvds (no pirate copies) and the same thing happens. The menu on the old dvd player doesnt have that many setting adjustments but I can choose between 525 interlace and 525 progressive (which makes the tv go crazy with a jumpy picture). When I connect it to another old tv, component works fine. So, where am I going wrong here?
