Default Dynatron SRX20

Could anyone give me some leaders/tips for no FM working on this chassis ?
I have not looked at it yet. brother dropping it off for me to try repairing. I am guessing it will be a transistor in the FM side or power supply fault? He says AM is working.
Many thanks

Faulty transistors are rife in these from what I've heard.

But check all the supply voltages are present and correct first.
