After playing with crt's thi sweekend the mrs has asked me to sort an issue with our tv.
It continuously switches from 4:3 to 16:9 aspect, during ads and during programs on all channels, I've had this before during ads as the broadcasters do not allways maintaing correct snyc during ads, but this is a digital system (freesat).
The tv works with a cross hatch generator perfectly, for 1/2 an hour.
i take it theres an issue with the vsync, is there anything I can do with this, I'm expected to be able to fix ot.
