Vizio Vo47l Tv; White Light Always Stays On, Black Screen, No Sound
I have a VIZIO VO47L FHDTV30A that stopped working. When you connect it to the power outlet all you get is the vizio white light, it does NOT turn amber and the screen does NOT turn on and does not get any sound. All the buttons are unresponsive. I have done the flash light screen test and nothing, checked the fuses and capacitors and they look to be ok. Would it be best to replace the PSU, the main board or could it be something else such as the screen itslef?

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.
