You seem to know that component works so why not stick with that if you can?
Yes I could launch into yet another HDCP discussion but it's not a sure thing as we mix and match TVs, cables and decoder boxes. Component didn't have HDCP so it had no reason to glitch like HDMI. Since the glitch only hits a few percent of folk the makers have been reluctant to fix it because it's fixed by replacing 1 to 3 things.
Frankly this, if a cable doesn't clear it up is a fine reason for a return as a product defect. That creates all sorts of headaches for the retailer and maker. They deserve it.
I have read comments dating back to 2009 on this forum and others relating to the very same problem. Some blame the TV Mfgrs, some the Cable company, others the Cable/DVR box from the Cable Company, and others blame the HDMI cable or even the Cable to the house and to the TV.
I would think that after 6 YEARS this D***N problem would have been solved by the industry, but, after purchasing a replacement TV for our excellent Pioneer Rear Projection that died after 15 years, here is what happened:
1. First two weeks using Component Connection (because I didn't own an HDMI cable), no problem at all with sound or video.
2. Week three, HDMI cable from Cable Co. installed and the problems started, screen goes blank sporadically and no sound also. I switched to other HDMI inputs with the same results.
I have purchased a high quality HDMI cable from Crutchfield, now I will see "if" this solves the problem.
But the issue still bugs me, WHY do we STILL have these issues after 6 damn years ??? If this does not resolve the problem, I am switching back to Component cable from Cable DVR box to Samsung J6300.....voltage works, Digital (HDMI) apparently is still VERY suspect!!!!.
