Dear Mark,

If you only have a horizontal line being displayed on your TV, it means that your TV set has a problem in its vertical deflection circuit. It will need to be sent to be repaired at an authorized repair shop or by a technician you trust for this service.

Hope it helps!

my tv turn off in about 3 min. and will not come on for 15 min.

Check and replace the T'Con board. It might be faulty. Seek tech assistance.

problem could also be inside the display panel.

my sharp tv was like that to but our tv color was blue with also gray horizontal lines i did cheack all d caps resis... etc dont know what to do LoL.

Visually, there is very little difference to the eye of the average consumer between 720p and 1080. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern.your tv is display format is 720p and blu ray is 1080p. what happen is it will be scaled into 720p. old tv set format is 480p 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another. 1080p, on the other hand, represents 1,080 horizontal lines displayed sequentially. This means all lines are displayed during the same pass. 1080p is the highest quality HD display format. 480p represents 720 pixels displayed across the screen horizontally and 480 pixels down the screen vertically. This arrangement yields 480 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.

this problem is field collapse usually causd either by the field oscillator or field output stage to advise you further i would need to look at the circuit diagram
