Hii guys, I am user of this tv. I have been using it for eleven mounths, in this I have got many mistakes in this tv. it’s operating system is very bad. in this tv only one usb port. I saw that two mounth after buying it, its screen play was not as high as it was at the beginning. apart from this, ability to capture it’s signal also reduces the weather drastically so if you want to buy any tv, ignore sony wega 21 tv. I believe this is not a reliable product, so you do not buy it.
