The New 52 Earth 2 version of Robert Crane (the Golden Age Robotman) has a head comprising a transparent dome containing his brain, with a flatscreen computer monitor on the front.

Eventually it transpires that they're watching people through these screens, and can communicate through them.

Played from horror in an issue of Transformers: More than Meets the Eye: In an alternate universe, the ruling council of Cybertron have replaced the usual means of surgical disfigurement with a new one where the victim's head is replaced with a TV, which they 'speak' through.

The leader, King Robot, has a flat screen TV for a head that is twice the height of the rest of his body. Nobles like Prince Robot IV, his wife, and their son have sleek heads with clear pictures in color. Commoners like Dengo have very boxy heads with grainy monochrome displays. How modern and decorative a TV head is denotes wealth, and may be a sort of Fantastic Caste System. Vaughan's Saga all have televisions for heads.
