Screen turning red/pink a few seconds after bootlogo (using PI2Scart with rpi3)

[bytestorm]

Hey all!

I have a strange issue. I have tried 2 differend RPI3 with original powesupply and another random 2.5A 5v psu but no luck. (tried different scar cables also)

After a clean install of retropie 4.2 and editing the config file with these extra lines:

disable_audio_dither=1
dtparam=audio=on
dtoverlay=vga666
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1 #240p

I get a really nice bootlogo, and I can see the text start scrolling, but a few seconds in the screen turns pinkish/redish and looks all wierd :/

I have tried 3 different CRT sets, (lumatron, philips, sony trinitron) and all 3 gets this wierd issue. (all 3 pal tvs but should support)

What am I missing? How come the picture looks good in the first few secs and then just changes? What really happens in those bootsteps? Its so fast I cant read it.

Heres a clip of what happens (sorry for the TATE view but I didnt think about it at the moment filming)



Anything else I need to change? (without changing the config all works perfect on my hd lcd via hdmi)

Thanks in advance for reading
