27" UN28H4000AF startup: snowy flickering screen for up to 2 minutes

I'm wondering if my  27" Samsung TV is worth repairing. Its picture and all functions are beautiful and flawless, except lately when I power it on, it has an intermittent, snowy flickering screen for anywhere from 30 seconds to a couple of minutes, before finally settling down and working great.

 

I've done all the usual things - checked cables, tried other HDMI ports, ran the self diagnosis (irrelevant because by the time I get through the menus, often the problem has stopped.)

 

I also opened the back and unplugged/replugged all of the mini-connectors, but that didn't help either.

 

I hate to discard this TV since it has a GREAT picture and GREAT sound, but the startup flickering is highly annoying and I suspect will only get worse as whatever part continues to degenerate.
