From your picture:
2 x 2SA1360 Y PNP Hfe 120-240 (still in PCB)(you previously posted wrongly as c1306)
2 x 2SC3423 Y NPN Hfe 120-240 (shown removed)
Datasheets attached.
Although the datasheets list both transistors suitable for "Audio Frequency Amplifier Applications", they are used in a Video output stage.
If the manufacturer made this change from the schematic you have, you are best advised to seek the same transistors for replacements.
As you have substituted the NPN's and not fixed the fault, you need to check/replace the PNP's.
The NTE373 is not the best substitution match for NPN 2SC3423 but should be OK to test with, then replace.
