You will have to check the caps and voltages.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Wii menu will not come on when power is turned on.


Do you hear any sound when you power the console on? I assume it used to work fine? Try disconnecting all cables from the back of the Wii, waiting about 90 seconds, reattach all cables and power on. Does the power light go to green?

in the power supply you have six

Electrolytic capacitors you have to take the cover off the power supply to get to them. 3 of them will be 1000 uf @ 16v and the other 3 will be 1000 uf @ 35v the tops of them will probaly be bulged up replace those and that should solve your problem. you can replace all 6 with 1000 uf @35v and get them at radio shack for $1.79 each.
