Hi Check the resistance on the 3.9ohm/10wat again if it is open then the fault it most likely cause by diodes. And C4429 is a cap either electrolytic or non electrolytic. If it is reading open it most likely is non electrolytic. C4429 is it blue, brown, orange or green. If soo it is non electrolytic and you will read open unless you test it with and ESR meter. Test 3.9ohm/10wat as I said before and if it is open check for diodes near it. The clear diodes with coloured rings will not cause the 3.9ohm resistor to short but the zener diodes will (zener diodes are black with a white ring around one end of it) so check all of those. Zener diodes should read a certain reading at one end and when read the opposite way should be bigger or smaller. If it reads 0 then most likely it is dead.
