Mid 90's GE TV Problem
Hi,
I know if you had the model and chasis number this would probably be more useful, but it's difficult to get that right now, but I thought I'd ask if anyone would have any idea on if this could be fixed. I've got a 1996 36" TV that had the tuner die years ago, but since that time I've switched to satellite and use the A/V inputs exclusively. But I've noticed that the "Unusable Signal" circuit that kicks on when the signal is...usable apparently, is becoming a lot more sensitive. I was used to it changing when the AV selector would switch sources or if a device was off...but I've noticed it's flicking on when commercials come on...or if things go to a bright scene. Is this a known problem for any of the units? Is there a way to just bypass that or do I have to live with it. |

You might try to disable the tuner part, and/or the rf-to-video detector. those might be picking up spurious signals. |
