I doubt it, there is no way it would be that inefficient.

- Power input specs will be worst case, ie current drawn spec will be the turn on power, it'll quickly drop.

If it really drew 33W, (constant) the thing would quickly melt, it has no fan or vents!

On the main circuit board towards the front of the case - look at the photo's - the track that curves away from the WiFi boards RF socket

Like most high tech these days, only repairable to board level, although the WiFi module may be replaceable.

As it is only $99, they probably won't repair them, or keep spares, so the only options are the WiFi board, connectors, and maybe the power supply (to component level that is), otherwise, over the shoulder..

Now if only someone can figure out how to get 'normal' audio & video out of it then a lot more people will be interested.
