It is possible that your CMOS battery has died. Look for directions on opening your laptop and check to see what type of battery your motherboard uses. Try replacing it and see if that solves your issue.

Sadly, you cannot upgrade the graphics card in an iMac. There is not an actual graphics "card" so to say inside of an iMac. Instead, the GPU itself is soldered to the logic board.

Try following this guide to remove the faceplate from the wii. Then check that the power button is not damaged on the inside.

You most likely need to clean the cartridge slot. If the N64 can't read the cartridge, it will not display any picture or sound. I usually clean my older cartridge-based Nintendo systems by dipping a qtip in %90 isopropyl alcohol (rubbing alcohol) and then running the qtip along the connector on any N64 game cartridge. Then repeatedly insert and remove the cartridge from the slot on the system. This will clean off any dust or dirt that has built up inside the slot over the years.

Your best option would be to open the phone up and try to clean it out as best as you can. I have had luck reviving water damaged phones by scrubbing the logic board with %90 or higher rubbing alcohol. The alcohol not only displaces the water, but it also helps to clean off any corrosion.

It sounds like it could be an issue with either the T-con board or the motherboard. If you haven't already, I would open the TV up and check the connections on the T-con and the lcd screen as a cable could've come loose during transportation.
