I have an old customer who has a 32" Panasonic CRT HD TV he wants to keep. He bought a Roku and discovered the TV doesn't have an HDMI input. I told him to pick up an Component to HDMI converter from Amazon and an HDMI and component cable. He called and said he couldn't get it to work, so I took the ride to his town and brought component cables, HDMI cables, and a blu ray player.
Sure enough, there's no picture. When I plug my Blu Ray into the TV via component jacks, it has picture and sound so the component jacks are working as is the HD section of the TV. When I tried connecting the blu ray player through the HDMI adapter, it had sound but no picture, so neither the blu ray nor Roku was working through the adapter. I thought the adapter was bad but took it back to my shop to try and was surprised to find it works on a newer Samsung. Is it possible the older Panasonic could get a blu ray HD through the component jacks but not work with an HDMI to component adapter? |

I think when a output device (the player or Roku) is hooked up to a monitor, there is a bunch of handshaking going on via the HDMI port between the two. If the HDCP isn't satisfied the display is compliant, the video blanks on the device. The component is analog, so either doesn't care. I know that there is a "black box" fix, rather than a cable, there is a box that mimics the HDCP handshaking with the HDMI. Usually has some dip switches to set for the monitors max resolution. I haven't seen one in 5 or 6 years but I'd guess amazon or ebay may be your freind. Sort of a fringe product. Personally I'd give the guy a clue stick and just replace the set. A 32" flat screen is $100 or less these days. -bruce |

If the HDCP isn't satisfied the display is compliant, the video blanks on the device. The component is analog, so either doesn't care. But that's why it's weird. My blu ray DVD plays HD through his Panasonic's component jacks directly. I would think the problem would have been between the HDMI source (either the blu ray or Roku device) and the adapter, except that the same blu ray player worked with the same HDMI to component adapter on a bit newer TV back at my shop.

A 32" flat screen is $100 or less these days. -bruce That's true, but a 32" 4:3 is much larger than a 32" 16:9, but he has several flats in his house elsewhere that have given him a lot more trouble than his Panasonic CRT, which has never had a single problem and, well, he likes it. I also think it cost something like $1800 when he bought it. Older people don't like disposable. In addition, a $100 32" TV has a lifespan measured in hundreds of hours. I'm going to try a different brand of HDMI to component adapter and see if it works for him. Thanks. |

Might there be a simpler answer?
don't most DVD players have an HDMI input somewhere and component output? If you could find one like that, you'd probably be out less money than buying the converter, and you'd have the advantage of being able to play videos through your CRT. Or, is there a chance that a Firestick would work where a Roku doesn't? |

Possibly. I have two Firesticks - when I go back with another adapter, I'll bring a Firestick to try. Still, the blu ray connected fine to the TV via the components inputs, but the blu ray also refused to work with the adapter through the HDMI in the same way as the Roku. Makes no sense. I'll pick up different adapter than he has and try it. |

I'll pick up different adapter than he has and try it. I would expect that the Bluray should work since the HDMI in this case is just an output. I would NOT expect the Roku to work since this requires the conversation to work and the adapter won't allow for that. If the Panasonic Bluray still fails, it may be from the first generation that IRRC required HDMI-HDMI connections only. |

Some have HDMI in and components out, I think. My cable box has a choice of HDMI or components out. I'm not sure what inputs. When I replaced our CRT with a flat screen I used the component cables as they were already in place. Later I discovered the slightly fuzzy picture was due to resolution mismatch and went to HDMI, the picture is much better now. We were given a Fire Stick and it works better than our old Roku, but neither gets used much. - |

They talk to each other, and they didn't work the first try. I had to have the LCD monitor on first, to get them to communicate. After that it has worked OK. If the monitor gets turned off, it will display a 'Do you want to continue watching ????' when it is turned back on. The Roku also has a menu setting to turn off a display or TV. This is the low end version, and I use it in my bedroom, next to my computer. It was bought at Best Buy about six months ago for $30. It only has a USB port for power, and a HDMI port. The OEM power supply is crap. It is too close to the actual current draw of the Roku, so I power it from my main computer. So far, it has worked well. It is on 24/7 to help mask my Tinnitus. |

If that doesn't work, I'm done. He'll either have to do without or replace the TV. The guy is like 40 minutes each way away from me. Not to mention I spent about two hours with him when he was asking about Rokus, terrestrial antennas, etc. to get away from cable. No matter what happens, this was a loss. I've done other stuff for him so I don't mind giving him the time, but I'll give it one more shot with the new HDMI adapter. If that doesn't work, I'll give him your info and see if he wants to try that (by himself!) |
