Brightness issues (?) During HDR playback

Itom86 — Wed, 08 Nov 2017 12:21:38 GMT

A couple days ago I've noticed that my TV -49xd83- making wired high pitch noise during HDR playback. The brightness is set to the max for HDR, but as soon as I start lowering it the noise stops as well. However when I watching SDR content the TV doesn't make any noise. Even when I push the brightness to maximum.

So it is only HDR with around maximum brightness.

I'm not sure if this is an issue, or the noise is coming from the back panel normally...

Has anybody noticed the same?

Hi @Itom86,

that sound like "coil whine" to me.

During HDR playback the maximum brightness values are probably higher than during SD playback, even with brightness turned up to maximum.

So can I open a ticket for this or there is nothing, that Sony can do about it?

Thanks!

Hi @Itom86,

if I were you, I would get in contact with Sony.

By doing so, you will at least learn, if it is normal for tgat particular TV, or of it indicates a defect.
