This sounds more like an internet issue rather than a tv issue. Is your tv a smart tv or using roku or amazon fire stick. Also..if it is a smart tv... do you have an ethernet plugged into the tv, or only wifi? You may not have a strong enough signal to stream video at your tv source. At times a wifi booster is needed. It IS possible your internet is too slow for reliable video streaming also.

Prime Video is available through your computer's web browser as well as hundreds of streaming media devices, including:

• Smart TVs
• Blu-ray players
• Set-top boxes (Roku, Google TV, TiVo, Nvidia Shield)
• Amazon Fire TV

Hello
Hisense doesn`t have Hulu. It has Netflix, Amazon Instant, Vudu, Pandora, Facebook, and Twitter. You cannot add Hulu.

Hisense recently released its new H6 Smart TV, which runs Android's 4.2.2 operating system, with a bevy of Android apps loaded on board, and a 55-inch screen for a record-scratching price of $700. The TV is available at Wal-Mart stores now.
China-based Hisense is known for its low-ball price points on both HDTVs, and 4K displays as it looks to carve out its own space in the highly competitive TV marketplace. But the new H6 looks to be one of its best bargains yet, especially if you love Google's take on app design. Baked into the H6's Smart interface are a plethora of apps, including Google standbys like Chrome, Youtube, Google Voice Search, Hisense's Cloud Services, High Media, for sharing videos and photos, and the usual suspects like Netflix, Amazon Instant, Vudu, Pandora, Facebook, and Twitter. One major omission is Hulu Plus, but it will be available at the Google Play store, along with a mountain of other choices.
