If the screen is all white or all black and nothing else works but the screen is on, it sounds as if the screen logic board has failed. There is not much you can do then than have it repaired. Your manual should have some kind on hard reset procedure you can try which may resolve the issue but if that doesnt work there isnt much else you can do.

    I bet a ribbon cable came unplugged, or has a bit of corrosion on it. I would take the back off the camera (small philips screws, you need a good mini driver set) unplug all mini cables, spray with CRC QD Electronic spray and put her back together. It is generally not worth repairing a P&S camera so nothing ventured nothing gained.

Youtube on my vizio 470i tv is off centered

The TV can display images in four different modes: Wide, Zoom, Panoramic, and Normal. Each mode displays the picture differently. To change the screen aspect ratio:
1. Press the MENU button on the remote.
2. Use the Arrow buttons to highlight the Wide icon. Press OK.
3. Use the Arrow buttons to highlight your desired screen mode and press OK:
• Normal preserves the content's original aspect ratio. Since the 4:3 aspect ratio is not large enough to fill the TV's screen, black bars are added to the left and right of the display image.
• Wide stretches a 4:3 aspect ratio picture to the edges of the screen. Since the picture is being stretched, the display image may appear distorted. If the program is already formatted for widescreen viewing (1.85:1 or 2.35:1), then black bars will appear on the top and bottom of the display image.
• Zoom expands images with black bars to fit the screen.
• Panoramic expands the display image to fill the screen.
images may appear wider than intended.
If you are watching widescreen (1.85:1 or 2.35:1) content, black bars will still appear on the top and bottom of the display image. This option is only available when the TV is displaying a 480i/480p source.

My TV image went blank, but the TV stayed on. What could it be.

The exact model number is necessary to determine the exact parts your TV has. Some models has suffixes in their numbers to indicate they have some differences in their parts. For example, the 42LG30 is different from 42LG30DC, 42LG30-UD and so on. But generally, there are three parts that has a direct connection with the dimming and illumination of the screen. These are the T-CON board or LCD driver, backlight and inverter or ballast. The T-CON board is responsible in driving the LCD panel to produce the appropriate video or image. The inverter or ballast provides power to the backlights to illuminate the screen. If one of these fails, you will not be able to see any image or video on your screen.
The T-CON board is bad when there's a glow on your screen indicating that the backlight is on but there's no video or image. In short, the screen is blank.
If the screen is black, no glow, grab a torch and shine it on your screen. You will be able to see a faint image if the T-CON board is good. This indicates that the backlight is off. Either the inverter/ballast is dead or the backlight itself is busted. But usually it's the inverter/ballast that has failed. You can tell that the backlight is busted if the TV is old enough that the mercury vapor inside the tubes has depleted.
The T-CON board and the inverter or ballast are not serviceable and must be replaced completely if faulty. Replacing these boards can easily be done. Feel free to inform me if you find which of the above is the root of the problem to guide you in the fix.
