Tv Philips 27TS54 vertical closed, no sound

[mza services]

Hello: I have a Tv Philips 27Ts54 chassis: 27B800-7562, this has not sound, and the vertical is closed, I change ic vertical (bad), Diode D409(bad), but i do not know,......Any ideas......thanks

STEPS:
1. Make sure to connect the IC and Diode correctly coz it has a pin guides.
2. Check the DC voltage of the vertical and sound stage, check the biasing parts of the IC like resistors and capacitors there might be a problem that makes the IC got defective. Use an isolation tranformer in making repairs just for your safety. Good day... i hope it helps...

dont forget to change low ohm resistor off flybackthat feeds the voltage usually 26volts to the vertical circuit
