Reverse polarity cannot possibly cause a problem to a 12 volt TV nor a 230 volt TV
Reversing the polarity simply means that your switches will be in the neutral conductor instead of the line conductor. Your equipment does not know one from the other.
Unless you are going to take your electrics to pieces while it is LIVE polarity is irrelevant
Although largely (but not always) true in terms of correct operation of equipment, putting the protection (i.e. fuses and breakers) on the neutral instead of the live is actually quite dangerous. Even if the protection trips, the equipment is still connected to the live.
Even worse, in the event of an earth fault, the current will continue to flow, possibly causing shock or fire.
