Problem with Q70b

[Theo1896]

Hello everyone.I have a problem with my new 3 month tv q70b.

The brightness is down to 90% from usual,I have tried everything myself, I have spoken with Support,we have seen everything ,we made a factory reset and they have told me that this problem is caused from an update.

Is it possible ?

They told me to wait 1 day.

What is your opinion?

Thank you

It seems that a new software update will be released that is expected to fix this issue.

More details here (in Dutch).

Just applied update 1504 and it appears to have fixed the issue. No thanks to Samsung whose advice was just to wait

I do have absolutely same issue, but with QE75QN95B, I bought brand new TV and only watched youtube for 3 hours, then noticed that the brightness started to dim automatically on the light scenes, also refresh rate became low (or it is a very noticable flickering). After awhile the brightness became as lowest as possible. I tried all possible settings and recommendations from Samsung and community, factory reset, updated the firmware using usb to 1503 (was 1430 initially), but nothing helped. When I turn on TV it is bright enough, but after opening any video in any app like youtube, netflix etc - brightness is going down. The "flickering" (or very low refresh rate) is from the power on.

I cannot update to firmware 1504 as my motherboard is T-PTMDEUC, for which 1504 version is not yet available. Does anybody know, if I should wait for an update that will fix this issue or it is related to motherboard hardware problem?

For years I believed Samsung and have a lot of devices from it, but now, I am not sure if it is the same company anymore.
