Default Marconi 2018 problems

I have a Marconi 2018 and experienced a problem with the unit over a year ago so most detail i have forgotten !
I would have to toggle the on off switch several times before it would display , granted the switch feels dodgy but then the unit just went flat dead.
I investigated the PSU board and checked around the rectifier blocks 2KBB20R
of which there are three, the suspect one here is D2.
D2 had a brown pcb heat stain under it like its been ongoing for some time also on one side of D2 rectifier has kind of bubbled up almost likes its been cooked, could this be the cause.
Are there any known problems with the PSU board documented on the forum please.
