It appears to me that one or more components inside of your iMac has failed. The issues with the horizontal lines points to issues with the GPU, display, or display connectors, but the prohibitory sign could mean that there's also an issue with the hard drive or hard drive connector inside of your computer. I would Contact Support for more help with repairing your iMac.
