Unless the sound is getting muted and the speaker icon shows with the arrow through it its a main board failure
Testimonial: "Main board sounds most likely thanks"
Sounds like a SLEEP timer or SNOOZE timer setting,
SOURCE: Vizio 42", have picture for about 5 mins then screen goes black.
also check the power cord wire coming from the back of the tv is loose from the tv side or perfect.
SOURCE: oven switches 'itself' off without the timer
I sorted it it is a simple solution, if you take the top of your oven you should see the problem...it will be big and black..dont spend a ortune getting it sorted i brought the part off ebay for less than a fiver.. just cant remember what it was called..very simple to fix though. Mike
SOURCE: TV power light comes on but no picture/no sound
chip on ic board repair shop might replace it and reprogram if the tv is worth the fix
SOURCE: Green Screen
Hi, how is the cable box hooked up to the TV? Is it HDMI cable or componet (red/green/blue) ? When you say totally green, do you mean the the picture is only green with the other colors missing or every color looks green ?
