Question

Only 3D Mode on Samsung TV doesnt work

Aug 30, 2018 5:17AM PDT

Guys I have strange problem that I am trying to resolve for couple of months now. Tv is 40uf6400 Samsung, works perfectly fine in normal 2D mode. But when I switch it to 3D mode, image is completely distorted with thick and narrow lines, vertical and horizontal, no flickering. Strange thing that tv is working normally in other modes, but 3D not. So it's not defective display, it must be something else. I tried to rest it, settings and all things that I could think of, no luck. Any ideas?

I will post image.

My advice is "do not fix."

This looks like a failed mainboard IF all other modes work fine. The CTR (cost to repair) may be more than half a new TV and new TVs no longer have 3D.

It's strange that all other work but 3D mode seams broken. It's funny but maybe baking in the owen can do the trick, since I did this few times with graphic cards and it actually worked. Thing is I have no idea is this software or hardware problem. Thanks for your help.

For TVs, the software test is

To factory reset and then test. If that doesn't clear it up, then it's hardware. You can try latest firmware but given it works otherwise I'd forget the 3D and just use it.
