3D function on KD-55X8509C
Although it has worked previously the 3D function on my Sony KD-55X8509C no longer works. Using either the Action Menu or Settings:display the option to turn 3D on no longer functions, it is set to "off" and cannot be changed, 3D content cannot be played either from a USB or from 3D content on Youtube although both have worked previously. Is the issue linked to the recent software update or is there a fault with my TV?

Hi there
I have just tested the 3D on my KDL-43W805C tv using a clip from YouTube (see pics below). The 3D option is in the Action menu and can be turned on. I can only suggest a factory reset. If that fails, can you provide more information. Such as which youtube clip? If its a 4K 3D demo, then this will not work.
Cheers

Thanks for your reply. Yes I have tried a factory reset but still no 3D. The 3D clips from Youtube that used to play fine no longer do. Then 3D food fight did work very effectively in 3D previously:

Im going to report the issue to Sony, as you arnt the only one. Another thread is :

I have a feeling the issue is isolated to 4K model/s

Thanks. I've also been in touch with Sony Support, they were unable to solve the problem via a telephone diagnostics test and a factory reset. The issue has been "escalated"by Sony and I am now waiting for an engineer call out/repair.

Thanks for this.
As a further update, DBS, the Sony locally designated TV engineers have
told me that after their visit Sony has been in touch. DBS rang me with a
number of questions that Sony required answers to including:
- Are the batteries in the 3D glasses flat
- What sort of content was I trying to view
- Was there an obstacle between the TV and the glasses
Can't say that these sort of questions fill me with any confidence that
Sony are addressing the issue.
Regards

Hi there
This is a classic case of the lack of communications between departments 😞
