I have a 49inch 4k led the brand name is durabrand model number 49S6600c. About every three seconds the screen goes bad and comes back. The color gets bad then returns to its normal state. At first it just changes color a little but is getting progressively worse. I would like to know whats happening and if its possible to fix. Ive included two pics one in its good state and the other when it goes bad please the bad https://ibb.co/8ctxSDV the good https://ibb.co/5Ykggbs
Test it with several sources, ports and cables, does it do this on all of them? Is it in warranty? If not, there is really no fixing those things, in fact your post is one of the only things you find when you do a web search for this TV model. Durabrand was an old WalMart brand of tube TVs, looks like someone bought/stole that name for cheap electronics, not sure if that brand is made for WalMart anymore.
