using component cables on ps3?

is it true that original model ps3's(fat) can play blu-rays in1080p with component still? Since getting a ps4 i needed to switch inputs for that and i have component cables for my ps2 and i figure why spend any money on a switcher right now when i can use those. But i was reading some articles that you need hdmi for blu-ray and dvd and some articles that say it only effects the slim models and that original model ps3 are not effected due to this being a hardware change not a firmeware change. Is this accurate or are all ps3's effected by this restriction on component?
