Question about Televison & Video
since audio is working it means it is well connected to your TV
for your picture try to relocate,
means to unplug it to the original position
and plug it to other video input
say your DVD player is connected to video 1 move it to video2
and watch if the same problem occurs
for coaxial cable connections:
have the cable disconnected first and power up your unit and see if problem still occurs.
having done that and still not having picture, you might have a circuit board failure inside the unit.
it might not power up well if the fault is repaired and corrected.
possible causes might be:
a) power supply - not having enough to power up the horizontal deflection circuits
a leaky capacitor perhaps
b) horizontal deflection circuits- might have partially shorted flyback, a shorted horizontal output transistor or both
hope this helps, thanks for using Fixya!

Normally these boards do not go out easily. Are you getting the blinking yellow light? I would suggest to leave the TV unplugged at least 4 hours or overnight to be sure to clear out or "reset" the tv.

THAT MAY OR MAY NOT BE TRUE, IF THE TUNER WENT OUT THEN YES, IF THE MAIN CIRCUIT BOARD HAS FAILED THEN NO YOU WILL NEED TO EITHER REPLACE THE TV OR REPAIR IT.
