Random White Flashes during HyperHDR

[tinoproductions]

Hello,
I have a WLED setup around my LG C2 TV with PicCap + HyperHDR installed locally via rooted TV (WebOS Homebrew).

Running WLED on a DigUno with a 10A 5v supply with SK6812 5v driving 151 LEDS.

When I use a static colour or any effects with WLED, it works as expected. No random flashes.

When the TV is on and HyperHDR is running the LEDS show the correct colour based on what is on the screen, but I get the occasional random white flashes on some section of the LEDS.

I actually have 2 sets of LEDS, one going round the back and one under the TV console, and it only happens for the ones round the back.

They are on 2 separate ESP32 controllers.

This issue only started when I updated the version of HyperHDR so not quite sure where to look. I have actually reverted back to 19 and it's doing the same thing.

Steps taken so far:

• Swapped power supply between Rear and Console. No change

• Changed WLED controller from DIY to dig uno. No change.

• Uninstalled and re-install PicCap and HyperHDR. It seems to remember the settings so I don't feel this was a true clean up.

I am at a loss as to what to try next. Any tips and suggestions are welcome.

Thank you!

Hi
Not sure how WLED works in this scenario but setting static color may result in sending one commend to LEDs or send this command sporadically comparing to high refresh rate during ambient-light setup working. If the flashes occur only in the same LED segment there is a high change that one (or few) LEDs on your LED strip are broken and it can be seen (flickering) under the load. See: #1125

Hi, thanks for the super fast reply!

I did think the same, but if it was an LED issue, I would have thought that the inbuilt colour effects would give a similar outcome and result in flashing?

I did see the link you posted.

I am going to look for another LED strip and plug that in and see if it causes the same issues, or it sorts it.

Thanks
