Can you explain your question in more details:-
1.What is the model number?
2.Is the sound normal?
3.How old is your tv?
4.Is there any blinking light in the front panel?
5.Have you tried anything to solve your problem?
Is there any blinking light in the front panel?-If yes then in what sequence?
What is the model number?
The model number will be displayed on a tag on the back of the TV near where the power cord is attached.
One last question:have you tried playing dvd and see if the problem still persists.
if the problem still persists then the problem is in the video circuit and a repair will range $120-$160.
Dont hesitate to ask any further if you dont understand even after accepting.
I will be always ready to make myself very clear.
