I have a sharp tv. the problem is when i turn on the unit it shows a single horizontal line then immediately relays clicks then turns to stand by mode. i already change the vertical ic.


Vertical scan output failure. That is the reason for this horizontal line, right across the center of the screen. Check and replace damaged component/s at it vertical scan output section circuit. Check the solder terminals of the vertical scan output IC; for any loose solder points. Contact any service technician, if you're not handy in electronics.

The problem is a vertical deflection issue, it means the picture from top to bottom has collapsed. The set will require two or three capacitors and an ic and it is quite fixable.
