Ok now I am looking at the screen and it is breathing (too wide) and
bouncing with horz. tearing. I have tried to use freeze mist to find the bad
part to no avail. When it is first turned on it looks better but after on
for about five minutes pincushion goes to hour glass looking and screen it
way to wide but then bounces back to normal then right back out again. This
tv is driving me crazy please any info would be great.
