It can be bad/bulged caps, bad mainboard and etc. You need tomake sure first that the output voltages from the smps is good.

Is there any output from the SMPS? or plain zero output voltage?
The first thing you need to do is to check the fuse and components in the primary side.

You may need to check all components in the primary side. Check also the primary winding of the switch mode transformer.

Try gently press from the front screen to see if the line gone or not. If yes then the monitor internal joint may have loosen and you need to apply some force to make the joint to have contact again. If the line is still there then the lcd panel may have problem. It could be the lcd driver ic problem or bad tcp package.
