Ceramic Capacitors on Panel Boards, Which Ones? - Samsung UE55	Can't Post

Hello, here with a Samsung TV problem ones again...

I think the problem is located in the panel itself, or at least on one of the boards that connects the ribbon cables and I am narrowing it down a set of 7 ceramic capacitors on 1 of 4 of the boards.

When measuring the rest 21 ceramic capacitors they all give me 400 in resistance on continuity test, the other 7 just give me short circuit, so I will need to remove and test them separately.

But... how do I know which ones I need to buy? They have no text on them at all...?!

Once removed do they still measure shorted (bad cap) ? Or do the two pads where capacitor was read low resistance (Something else in parallel in the circuit) ?

I have now removed all 7 of the caps, when I removed the last cap low resistance came back between the pads so I assume the last cap was the shorted one.
In the process though I accidentally removed 2 or 3 smaller caps on the side (don’t rly have the tools for it)

I just wanted to make sure the panel kicked on and wasn’t cracked before trying to find a donor board or the correct components so I plugged it in expecting removed lines, to my surprise the TV worked as intended without all the caps? Why?

I assume I shouldn’t use the TV like this but is there any real danger to it?
