Hie
I would like to thank you all for helpfull postings & replies. Well, I am having a problem with Panasonic FX74 CTV. This set works fine for 3 to 5 hrs & then behaves as if the screen voltage has been increased. It will show white raster & flyback lines then horizontal line at the centre (frame collapse). After 30 seconds it goes to standby. If you switch it on, it responds & can play for another hour. I have tried the frame stage, replacing capacitors, jungle IC AN5607, but that did not help. What can be causing this problem? Pliz help.
