TiVo causes TV to display only B&W
I purchased a new 375-hour TiVo system from weaknees for my wife for
Christmas. I connected it that day to a TV that had had a older TiVo on it for about a year. Both are Series 2 units. The new unit worked perfectly until yesterday. Since then, I am losing color on the TV. When I first turn the TV on, everything is in color. After about 30-40 seconds, it goes to B&W only. If I use one of the TiVo menus, it goes to B&W in a few seconds. If I connect the TV directly to the cable box (bypassing the TiVo unit), the color is fine. I have a call in to weaknees, but I thought I would check here, too. -- Using a TiVo Series 2 (TCD24008A) Connected to Comcast Digital Cable (basic) OS: Win 2K SP-4 (5.00.2195) Email: Usenet-20031220 at spamex.com (11/03/04) |

Try a different S-Video cable, or wiggle the one you have around in the sockets and see if the color reappears. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

I have a call in to weaknees, but I thought I would check here, too. Let's get wiring out of the way first, they'll want you to do that anyway. Try whatever cable interconnect you're not using right now, will either isolate or confirm a few things. Dave Hinz |
I had a loose s-video cable cause the same exact problem.

RF? RCA? S-video? I don't know the names. It's a 3-wire cable (red, yellow, and white). All three cables have a male connector on both ends inside a metal cylinder. It goes from the Output-1 on the Tivo to the the Ext-2 on the TV. The Ext-1 on the TV has the same connectors for audio, but video is labelled S-video and it's a completely different connector.

Try whatever cable interconnect you're not using right now, will either isolate or confirm a few things. I tried 3 things: 1. I bypassed the TiVo altogether. I unplugged the 3-wire cable from the TiVo and plugged it into the cable box. Everything worked fine. Full color. I think this pretty muich eliminates the TV and the cable box. Plus, when I change the volume, the regular volume indicator comes on in full color even though the show behind it is in B&W. 2. I tried 2 different sets of cables. No success. I don't think it's likely to be the cables because one of those sets has been in use for almost a year. I think this pretty much eliminates the cables unless all 3 sets are defective. 3. I moved the cables from the Output-1 to the Output-2 on the TiVo. Same result. I tink this pretty much eliminates the jacks. What is curious is why the color comes back after I power the TV off? If I turn the TV off (using the TiVo remote) and wait at least 10-20 seconds, when I power it (the TV) back on, it's in full color for around 10 seconds or so, then it goes to B&W. That makes me suspiscious of the TV, but it doesn't happen if I eliminate the TiVo box. Still no reply from weaknees. -- Using a TiVo Series 2 (TCD24008A) Connected to Comcast Digital Cable (basic) OS: Win 2K SP-4 (5.00.2195) Email: Usenet-20031220 at spamex.com (11/03/04) |

When I was swapping cables, I did notice that the sound would breakup as I was moving the cables, but I cannot reproduce that now. But that was the sound, not the video. -- Using a TiVo Series 2 (TCD24008A) Connected to Comcast Digital Cable (basic) OS: Win 2K SP-4 (5.00.2195) Email: Usenet-20031220 at spamex.com (11/03/04) |

... I don't know the names. It's a 3-wire cable (red, yellow, and white). All three cables have a male connector on both ends inside a metal cylinder. It goes from the Output-1 on the Tivo to the the Ext-2 on the TV. Those are RCA connectors. The only one you're concerned about here is the yellow one, as that carries the video signal. 1. I bypassed the TiVo altogether. I unplugged the 3-wire cable from the TiVo and plugged it into the cable box. Everything worked fine. Full color. I think this pretty muich eliminates the TV and the cable box. Plus, when I change the volume, the regular volume indicator comes on in full color even though the show behind it is in B&W. And it holds if you joggle the yellow plugs a little on both ends? 2. I tried 2 different sets of cables. No success. I don't think it's likely to be the cables because one of those sets has been in use for almost a year. I think this pretty much eliminates the cables unless all 3 sets are defective. Seems reasonable. 3. I moved the cables from the Output-1 to the Output-2 on the TiVo. Same result. I tink this pretty much eliminates the jacks. Save for the ones on the TV itself, but I think you eliminated those in Step 1. What is curious is why the color comes back after I power the TV off? If I turn the TV off (using the TiVo remote) and wait at least 10-20 seconds, when I power it (the TV) back on, it's in full color for around 10 seconds or so, then it goes to B&W. That makes me suspiscious of the TV, but it doesn't happen if I eliminate the TiVo box. I'm inclined to agree. What's happening is that the actual color information isn't getting to whatever part of the TV needs it. For reasons of backward compatibility, when TV's went color, they simply included the color information on a seperate band from the B/W signal. So a B/W TV is simply a TV without the circuitry available to interpret the color band. Now, with the Tivo in the mix, you have two sets of RCA cables, one from the box to the Tivo, and another from the Tivo to your TV. Have you tried BOTH sets of cables with the box-straight-to-TV test? Have you tried reversing them, and plugging the other end into the other device? If it IS a connection issue, it could be something so simple as a single certain plug in the system not liking a certain connector, and if you eliminate that combination things get fixed. I've seen it before. Do you have a buddy with a spare TV you could try plugging this Tivo into? That would eliminate some options real quick. :) -- Chris Lemon http://fredsmythe.com EFNet: FredSmyth |

Next, I would try to determine if the connectors are loose which may indicate a broken solder joint inside the device. Be sure to check both the TIVO as well as the TV. |

A component has gotten old and is susceptible to heat. Since dust causes heat build-up (by acting like a blanket) you might try blowing out the unit using the blowing connection on your vacuum cleaner. LB |
