Screen looks like a picture negative, PIP works fine, sound fine


Sony's have dual tuning systems to allow for the separate PIP channel. The common problem on the Sony's is the circuit board and tuning module connections go bad. It is likely that the connections on the board or module were already in the decayed process and moving it just accelerated the issues that were inevitable.

The quick fix is to swap the PIP over to the main picture or to bus the antennae signal to the antennae B terminal thus bypassing the bad tuner module.

The recommended fix action is to have someone with soldering skills to remove the chassis, and locate all the cold and cracked solder joints, especially near the tuning modules. If this does not take care of the problem, the tuning modules will need to be removed for re-soldering on the actual tuner modules.

If none of the above works, then you can always use the audio/video outputs of a cable box or vcr to the a/v jacks of the tv, thus bypassing both tuners in the tv.

Ilo problem


What I hear you saying is that your main television tuner shows lines only while the PIP is functioning properly. The PIP works by using a separate tuner from the main tuner of your television (like a vcr tuner). Since the PIP works then it appears that your main tv tuner is not working anymore. It will probably have to be replaced. I recommend looking at our online technician list for a professional near you.

Good luck :)

My JVC PIP Won't work, pls help!


I was told that in order to view 2 different channels at the same time u have to subscribe to SKYCable and use the digital input instead of the antenna input and the antenna input you will have to use the regular antenna since there is only one tuner in the TV

Foot note to issue


If the source to the PIP input is a color signal then the PIP display will be color. PIP sets have two video sources one goes to the main screen while the other goes to the PIP. it all depends on what the format of the signal is being sent to each input. This is quite normal.

Main screen color seems overmodulating. PIP subfeed color fine. White like under black light.


rule number one about all vs chassis with vertical can pip boards take them out and throw them away i could fix one but you couldnt beleive me and it wouldnt be worth your while do a search on your modle number until you come up with instructions on how to add two caps to the pip board connector to bypass it until you do this you are wasting your time Mitsubishi ... we're still building Zeros
