I have 3 STB running Fios, since the fios guy came to update my central FIOS box outside, I have been having one tv intermittently go blank (Video only / Audio still works) between 5-20 seconds. At the same time the component input heading appears on my Samsung TV.
I thought initially it was a TV issue, then a STB issue, then a cable issue. I checked all and all werent the issue. I noticed that when I click to the FIOS guide the image stays stable. I researched and found that several FIOS customers a few years back had similar issues which they pinpointed to a degradation of the signal either.
It was suggested that I find a signal booster which is MOCA compatible. Does anyone know if such exists and if so, where I install it in the line?
Alternatively, is there a setting in the main fios box itself that may boost the signal? saving me the issue of buying and installing the hardware booster?
They can be more trouble than their worth.
You would be much better off if you worked to upgrade coax and splitters.
With just 3 STBs and a router, you should not have a signal issue unless you have poor or bad coax, or a bad splitter.
What model STBs do you have?
They have diagnostics to tell you what the signal levels are.
