You say voltage is up on pin 8, this is progress, but you still have to isolate the fault, and that will take a few steps, of chassis in/out going by what Squirrel boy suggested.
== Try disconnecting pin 2 of L3, A7, same coil, and feeding that tuner subber signal to G1 of V1, to see if possibly that trap circuitry is killing your IF signal..... Just be sure your V1 voltages don't change, like possibly G1 changing bias or something... == If you get a picture when you do this, then L1,L2,L3 are out of tune, if you do not, and still no video when trying to feed to pin 2 of V1 (which should be 3-7v depending an AGC, ) then L4 is likely out of tune.
