Component output color issue of IO Board 6.0 from Aliexpress

Unread post by nemopapa »

Hi,

I'm trying to find the root cause of the component output issue of io board 6.0 which bought from Aliexpress.
Some of my friends also has similar issue with component output.
Configured mister.ini with ypbpr=1 and sog switched on and not configuration issue.

See attached picture from HDMI vs TV.
Coloer level 0~2 distorted on yellow box.
You could easily found it on neogeo metalslug game.

Removal of capacitor C6 also not related.

Looks quality issue from Aliexpress, it's not found from io 6.0 purchased from UK addon shop.

p.s - I'm suspecting that Aliexpress uses lower value chip resistor.

<Aliexpress>
201 = 200ohm, 471 = 470ohm

<UK>
2400 = 240ohm, 4700 = 470ohm
