Pioneer video issues

[dbrashear]

I can't figure out how to describe the problem well, so it may be described here, and I'm failing to search it. My Pioneer unit is outputting purpleish, full-screen-width bars of distortion which slowly climb the screen, then restart from the bottom. It's not a bad cable; it happens with component or s-video (i didn't try composite). it happens with multiple TVs.

is there a missing choke, is my power supply dying or am i just losing?

Do you get the purple bar if you connect the cable feed directly into the TV? What is your signal source? Cable with no box, Cable with box, Satellite, OTA, OTA converter box, some combo?

It sounds like you have a RF interferer somewhere, or a bad power line. We need more info to help you diagnose this problem.

It's cable to the TiVo (no box), but that doesn't matter: the TiVo menus also have the interference.

Sounds like you have a bad unit. Probably the motherboard. Did you experience a power glitch recently? Is the TiVo on a UPS? Power spikes are not good for TiVos and can do random things to them.

Do you see the distortion on recorded shows? How about if you transfer the show to your computer via TiVoToGo?

I had one Pioneer simply stop working. It started doing weird things, like not responding correctly to the remote and not updating to new software. I moved the subscription from it to another Pioneer and started using the bad Pioneer as a parts machine.

I know that doesn't help your situation. You may have to replace the unit with another one. PM me if you need help finding a replacement.

Good luck,

Sadly, this unit has lifetime. Anyway, it's been on a UPS ~forever and is now, too. I'll have to try TiVoToGo. Watching recorded shows, though, pausing the show does not pause the distortion, so I presume the distortion exists only in the video out path.

Which output are you using? S-Video, Composite or Component? Have you tried all outputs?

component and svideo give the same interference, but it got worse when using svideo with the component disconnected

Try different wires to find out if your current wirings is bad or not.

There was only component until 3 days ago, when i added the svideo cable, and the problem stuck around. i suppose i could try another svideo cable but i doubt it will make a difference. i get the interference whether the svideo goes to the receiver or the tv directly; the receiver doesn't do component, so the component does and always has gone directly to the tv

Well, the wiring's apparently bad, but not the wiring I expected: I swapped the TiVos, and now the HD TiVo (downstairs on that TV) has identical interference, whereas the 810 has none!
