Default Re: TCL 75R615 has sound, no backlight

So, I got some help yesterday to take the TV off the wall and got the back off to check out the boards....I did find a capacitor that was blown out,looks to be C312 a ceramic disc capacitor, very small and challenging to read, but was able to with a magnifying seems to be a 220pf 1kv, I ordered some new ones from digi-key. A couple of questions, I dont notice with this type of capacitor that there is any polarity that needs to be observed? I have replaced numerous electrolytic caps and they have obvious polarity markings on the circuit board as well as the cap itself. Please see the attached pictures of the part number of the panel as well as some pictures of the internal boards, please offer up any help if you can....Thanks.
