Picture went very dark last night. when i turned it on this morning there's no picture at all now. still sound though

It could be your mainboard. How long did you have the TV?

Hi,

If you turn the tv off for about 1020 seconds, turn it back on and see if you have a clear picture, if not it sound like a power supply problem in the tv. but if that did not solve the problem, the picture board on your tv is now malfunctioning or as gone bad, it means the picture board of your tv has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your tv to solve the problem.

It sounds as though either the backlights or the inverter(which supplies power to the backlights) has gone. If you can still see the desktop but only if you look closely and it is very dark, then the monitor will need repairing or replacing. If it is the invertor it can be done at a resonable cost - if it is the backlight it would probably not be worth repairing. Also it will cost just for an engineer to check it out.

It sounds like the main board or screen may have gone
