Black screen and no sound
The problem is most likely the the screws are loose on the inverter
boards. The screws must be tighted as they provide the ground to the
inverter bds. The inverter boards are undet the shields on both sides of
the unit after pulling the back cover. One way to make sure that you
are losing back lights and not video is when your picture goes black,
shine a flash light on the screen at an angle and will see the video is
still there. This mean the back lights are out. If you do not see the
video it may be another problem

Hello,
Yes there is a tale tale sign that you have a blown fuse in the power supply or at least the components inside are not working in order.
A bad power supply would mean a dead TV. Now this does not mean you thorw the tv in the trash and forget it exists. You can purchase the power board itself from www.shopjimmy.com or www.partstore.com. I have seen many people repair these and know nothing about them for under $100 bucks. Not all results are guaranteed tho it will depend on your knowledge.
No stand by light, means no power is being delivered to the TV, Bad power supply or fuse.

The Wii will work on the TV. Just try plugging into the ports labeled AV1 or AV2. The red, yellow, and white holes should line in a row with AV1 and AV2.
After you have them plugged in, press the INPUT button on the TV or the remote to get to the AV1 or AV2. It should work after that. :)
