Sony 4 has a minor problem. When you turn it on, there is no signal on the TV. The reason is a problem inside the Sony. I don't know what it is. You can take it to a Sony repair shop and they will fix it for you, or you can fix it at home. The reason for selling is that I bought another one. (Selling to the highest bidder) Location: sometimes I deliver to Tharmada, Athithiyah, and Shaqra.
