If the line is present in all inputs and modes, there is a problem with the LCD Panel. The only way to fix it is to replace the whole LCD Panel which is very expensive (usually around $1000+ for 40" Sony). Unless the TV in under warranty, it is usually around the same price for a new TV.

Check your cables first to see if they are causing it. Faulty cables can cause all sorts of problems. If that doesn't solve it it could either be that the colour settings are wrong, for example NTSC instead of PAL or vice versa. Sometimes it is something to do with copy protection. In some cases counterfeit discs, or faulty discs. And in some cases a fault on the DVD player.

Hi there...it is sounding like a backlight is going/has gone out...these can be proffesionally replacedat a repair shop...To self diagnose if it is the backlight take a flashlight and, with tv on and while on a tv channel and carefully form different angles look into the 'dark' part of the tv screen...if the/a backlight on a lcd tv/monitor goes out(even laptop screens) then u can still see a faint image with a flashlight(or without one with a good eye)....If you still see the (tv channel) image, then it is most likely a bad backlight......
I hope this helped you some, if it did(or not) please rate!...Thank you

You either have a problem with your power supply board or main board. I would start with having the power supply fuse checked as well as the power supply board!

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

If your TV seems to be darker than you think it should be, it is possible that the problem is with the light sensor. The light sensor will automatically adjust the picture brightness based on the ambient light that is in the room, (i.e. if the room is bright the picture will also be bright, if it is dark the picture will also be dark).

To turn this feature off go to Settings > General Setup > Light Sensor.
