There are several things in play here. It is common even for Japanese companies to have goods made by other specialists. Sometimes it is a way to get one part of a conglomerate to keep working by supplying bits to another company, possibly not even part of the same group. I used to know a regional manager for Sumitomo who surprised me by the tales of contracts he had assembled to sell major contracts for e.g. a Mitsubishi main contractor because Sumitomo had a factory in danger of going onto short time, if it did not sell its specialised product.
CD/DVD drives were made by one or two factories at one time but appeared under a range of names and so on across the board. Inter-company Japanese contracts are like nothing you have ever seen unless you have seen a Japanese contract. Typically it might run to three or four lines which basically say, ‘We trust you to make what we want’ and that is that.
That a TV, or anything else was actually built by other than the name on the front is no surprise at all, it even happens with cars as well.
