Hi, I picked up an old Teledyne/Packard Bell TV console with a
integrated Cartrivision video tape recorder. For those who are not familiar with this, the Cartrivision was the first mass produced cartridge based video tape recorder for home use. This was on the market in 1972 or so. I got the thing for free but I had to drive a ways and it was very heavy lifting into my home. They sure don't build them like they used to. Anyway, it took a couple hours of warming up and pushing the on/ off the power button to get any life to the thing. The sound was fine but the picture left a lot to be desired. I assume the picture tube is bad because there is just a steady white horizontal line in the center of the picture, along with some rolling lines. The VTR section did not work either. I figured out why as I looked in the back this morning. The power to the tape section had been disconnected and the 7 audio/video wires that were supposed to connect to the interface on the TV chassis were cut and tucked behind the signal processor on the VTR side. I initially thought that the tape recorder just stopped working and they wish to isolate the TV. BUT, I noticed when looking at the front controls that the chassis is a "Quasar II". The chassis does not fit totally into the space in the console as there is maybe a good 1/4 inch gap on each side or so. So, I am not sure if someone has modified this TV or if Teledyne would actually use a Quasar chassis. Anyone know if this could possibly be the case? Could a Teledyne picture tube work with a Quasar chassis? They both have 2 tubes, 2 in the chassis and 2 at the base of the picture tube. Because without the proper chassis and interface this is just a heavy paperweight, though the Cartrivision components have some value. thanks, CTV |

If you do what you can and still cant get any of it working, maybe another enthusiast could get it up and running again. Not sure what the attraction would be with cartrivision though. NT |

Perhaps collectable value. ![]() If there is light and lines on the screen, you're close. That means the high voltage power supply and deflection is working. As noted, not the picture tube. Possibly tuner or other signal related problem. Bad connections, bad electrolytic capacitors, a missing power supply voltage. The fault may have been present before it was "retired". You'll need a schematic and some troubleshooting skills to get it going but the TV can probably be made to work but don't expect the performance of modern TV. As far as the video section, that's probably more of a challenge but might be possible. Hi Sam... With the greatest of respect; looks like you may have over-looked the horizontal white line. Looks to my old eyes like he's just lost all vertical deflection. Don't know the set, but if it's a tube type, perhaps as simple as replacing the vert out tube if he can find one? Take care. Ken |

Ken- Hide quoted text - - Show quoted text - Hi. Thanks for all of the replies. My question though was more of would Teledyne/Packard Bell produce a console set with a Quasar II chassis? The reason I need to know is that if it has been modified, the interface for the VTR would be on the original chassis and this would now be totally useless as a collectors item. The TV and recorder can always be fixed. Another clue is that the back panel has some cutout for fine tuning pots, reset button, etc. that do not correspond to anything on the back once the cover is taken off. So, either someone has modified it or they changed their design mid-production and went with a different design. Though I believe this was their stereo model so maybe they went with a different design for their stereo model? thanks, CTV |

I was going to suggest that you give the owner of http://www.angelfire.com/alt/cartrivision/ an email, then I realised by your email address it's you! Good website. At that time wasn't Quasar part of Motorola? Any OEM connections there? I never knew before about this format, but then I'm a fellow from the UK & the first cassette handling video recorder sold here was from Philips, the N1500! -- Adrian C |
