Power light stays solid green all the time. Cant see screen with light so I dont think it is a backlight problem. Any suggestions would always be welcome.

Re: Sceptre X7 powers up then display turns off..
OK , we should try to check the voltages first.
On the blttom left side of your picture, there is aoldered in fuse, check that first since it is the fuse for the backlights inverter circuits.
Since you are working with the line operated device, you should plug this into Isolation transformer for safety. Caps seems to look OK but do not mean they are not bad.
Post good clear pictures of the bootom side of the power supply board.Never stop learning
