Default Re: TX98 Blown up power supply

It's definitely stuck in startup - i.e. trip mode. You've done basic checks on the primary, so have a look south of the transformer to see if there's a short or leak there. You could disconnect the feed pin to the LOPT to isolate that stage - that won't do any harm.
