And I don't know of any DVD players that have an HDMI input. Maybe a small TV or computer monitor? 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. - |

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 use a Roku Express with a sevenn inch HDMI security monitor. 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 I send them to Jeff, it's a direct (and particularly nasty) assault certainly, but I think I'm OK as far as WMD go. |

I can confirm that shorting PS_ON + GND will *not* power up the unit. There's an immediate 'click' but no power-on. I'd be grateful for any input on this. Thanks in advance. JHM |

That's easy, fucking with a defective power supply isn't worth killing a mother board. Throw it in the trash. -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com |

Normally those kinds of circuits requie some sort of feed back information to keep it alive... I Suppose the proper thing to do is watch that feed back information to see if this is the case. In some cases it could be a rather high speed pulse coming from a Digital timer or CPU. when that stops the circuit will time out and shut down.. I assume this is what you are referring to ? |

It might be that there's some oscillation at the sense amplifier; the impedance of the probe wiring might be the issue. If so, good news; that means it's not gonna need a new probe. Bad news, you have an oscillating consumer device to debug. |
