Above is your user manual below is a service and repair manual.
Indeed i would suspect something around your Final Output semiconductors, and any associated resistors?
You really must obtain a service manual, here there are the troubleshooting steps required to isolate and hopefully allow repair of your unit.
Look for any discolored components etc, check if any are overly hot... use a temperature probe on suspected components. Freeze spray may also be useful in diagnosis.
Use your eyes & nose to isolate the bad burnt overheated components, I sometimes use a straw up a nostril and selectively go over suspect parts, and "Sniff" to try and detect the overheated smell... it works.
Above is your tech support link, contact them for any info you require.
