    Series 3 HD Tivo Picture Quality mostly green/yellow

    Am using a Series 3 HD Tivo with a single 750GB drive, all bought from Weaknees in May ’07, pumping signal from Verizon FiOs with 2 cablecards into my 55” Mitsubishi Diamond series WS-55711 bought in summer ’03. The TV has already been serviced only once, in May ’06, due to ghosting on all channels (I generally recall that a convergence-related amplifier and/or board was replaced, plus the tech did a SD-HD convergence and fine alignment service).

    Today's Problem: my picture quality has suddenly degraded. Clarity is unchanged, but colors have gone downhill. Everything coming out of the Series 3 Tivo has a significant green and or yellow predominance on all channels.

    To try and isolate the problem as either my Tivo or my TV, I plugged in a standard Verizon digital set-top box from another room into my TV and colors are normal, so am guessing the problem is not my TV. TV picture is fine also with a DVD player and a VHS VCR as input. I would like to see what signal is coming out of my Tivo by using a different TV, but my big screen is the only set I own that accepts component input, which is all my Series 3 box puts out.

    I’ve done a complete system reset on the TV and I’ve manually set all of the picture/brightness/tone/related setting to the middle or default settings which had no effect on the picture quality of a program being played by the Tivo (either pre-recorded or live).

    Any suggestions?

    So did the other Verizon box use component output also? Same cables?

    Does your TV accept HDMI? Or DVI?

      Michael, appreciate quick reply…

      The generic Verizon box does NOT offer component output and is “meant” to be used (99% of the time) with RG-6 style coax cable. Here’s the manual http://onlinehelp.verizon.net/consum...0userguide.pdf. The available back panel connections are on page 9. Other than coax, there’s basically just some RCA jacks. But the picture quality is fine (no evidence of my green/yellow problem) using this generic Verizon box and coax cable.

      The TV, built in 2003, does NOT offer HDMI or DVI inputs. Tivo offers HDMI-out but I have no way to get that signal into my TV. Here’s the TV manual http://www.mitsubishi-tv.com/pdf/own...s/WS-55711.pdf. The available back panel connections are on pgs 13 and 14 of 92. My Tivo’s component cable is plugged into block 7 (DTV input) and my DVD player’s component cable is plugged into column 1 of block 6 (component input). ANT-A and ANT-B (block 3) accept coax input, which is how I tested the generic Verizon box’s signal, as does ANT-DTV (block 8) which is meant for over-the-air signals delivered by coax.

      I considered that this might be a bad cable, but until this problem popped up haven't had any picture quality issues that would make me suspect the cable had gone bad. It hasn’t been physically moved lately (no reason to suspect it got hit or had some external damage). I think I have another one, maybe I’ll try it just to be sure. Am not optimistic this is the answer, otherwise stumped.

        I would just take the component cables that are going to the DVD cable and plug them into the TiVo. That way you'll be using different cables and a different input. See what you get.
