Multimeter reading 0.00 on whole circuit

I am trying to find out why the entire circuits reads 0.00 or shorted. I even have a couple components that when i take out of the circuit still read 0.00. I dont understand if its just one component thats shorting and causing the rest to short or how that works. If they are in parallel i dont understand how every component in the circuit is shorting. Can anyone explain that and explain if a component reads 0.00 then its bad right.

sorry im new. forgive if i take measurments that dont need to be read or mess up. its weird they are reading differently now, not all of them are showing up shorted.

Its on page 42 bottom left corner of page. S501 is the beginning. heres a list of the components measurements in that series. Measurements are in circuit and ill write if i tested them out of circuit.

OH and how do i find the one thats making them all in the 700s instead of 400s like the schematic says

F801 000
C852 785 and OL out of circuit
RV801 783
J801 EMPTY
RT802 000
R986 265
R985 265
R984 265
L803 2-3 785 1-4 788 2-1 000 4-3 000
C804 793
C802 OL
C801 OL
L804 2-3 788 1-4 792 2-1 000 4-3 000
C829 790
C891 OL
C892 OL
VB801 I DUNNO HOW TO READ CAUSE THEY ARE IN A STRAIGHT LINE and all read OL except one which is 783 which are the middle two pins
C805 OL
C806 OL

should i keep going or is this a waste of time for you guys

pretty sure the rt802 which is not parallel is bad and causing trouble. thank you for anyone willing to help, hopefully i can go through with what im doing showing the readings and pics and get help. if there is a different place on forum to do this let me know. basically like having someone go over all the readings with me to help me understand whats wrong. or if anyone wants to pm me and do a video it might be faster if you wanna take the time.

Thanks

The value of the resistances you are measuring are quite low (For example R984, R985 & R986 are marked 274 ohms.) so these would probably read zero on that range. I suggest you use the 2K ohms range.

They are surface mount components marked 274, so have a resistance of 270k
