Hi Zebidee, thanks for this guide, it's really in-depth and helped me out a ton
. I'm in a bit of a pinch however, as I completed the component mod on my TV but cannot get the factory menu open to enable YUV. My TV is branded as a 'Sonistar T-1499', and it uses the LA76931 jungle chip. I found a factory manual for the chip, which I will attach below. The factory mode information is on pages 57 - 62 and the gist is: 'Press “M” key to enter into factory mode, “M” will show on the top left corner of screen.' and ' You need a repair RC(model: HYDFSR-N-GEO)'
I'm assuming that means it's not possible to bring up the factory menu with the normal TV remote, have you ever run into this before? I tried looking up this HYDFSR-N-GEO service remote, but I can't find anything helpful. I just don't want my work on the component mod to waste
, so if you know anything I can do, that would be great!
Thanks.
