Customer Question
Samsung un46f6400 At times...

Samsung un46f6400 At times more often than not, the on screen channel display is not bright and when it is bright the picture is a better. This happens when we change channels. So display dull, picture dull. Display brite, picture bright. Can you follow my jargon?

Technician's Assistant: How old is your UN46F6400?

May 2013

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

On antenna and cable

Technician's Assistant: How long has this been an issue with your UN46F6400? What happened right before this?

It has been going on for years. T

Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review and reply.

So is this an intermittent issue where the brightness fluctuates on its own?

It is more lack of contrast. Today I turned the tv on and it is back to dull. Not the best picture. It doesn't do it while watching but happens changing stations. Maybe I need a new tv.
TV Technician: Nathan, Installer replied 7 months ago

But it happens on antenna too, or perhaps other sources like dvd, apps, etc?
Not just on cable?
