Dear Buyer,
It is recommended that you go for items with valid warranties, as Sapana said.
But you should keep in mind that most items on eBay come with a Dealer Warranty which is a lot different from that which u get when u buy a TV.
You will probably find that goods without warranties do come cheaper and there are plenty of choices. So what I suggest is- look for the seller reputation while buying anything, and not entirely rely on the Warranty ! If possible ask previous customers of that seller about the quality of items and service offered.
These are some consideration you shud always keep in mind! 😉
Wishing you,
Merry Christmas & a Happy New Year,
BYE!!
