GE Porta Color model id help and future repair help

[john116]

Hi - am trying to initially identify the correct model/chassis for this GE Portacolor (pictures below), and also find service information.

It currently partially works, with a few issues as noted below (note also, am in Australia, so using a step down power transformer, and also a digital set top box with a UHF output on channel 26, in NTSC format, sound carrier set at 4.5Mhz.

1) Picture is watchable on screen, but lacking in colour, turning colour control down gives black and white picture, turning it full up, give only the faintest hint of colour. Colour appears to be correct. Tint control doesn't seem to do anything although this may be due to colour problem.

2) The AC power cord is very loose on the pins in the TV? It may be the wrong cord. I notice the back panel of the TV mentions interlock, how did this work? Is the power cord supposed to be attached to the TV panel back?


So aside from the color issue, I have a mostly stable picture with sound.

Any help greatly appreciated.
