Prudence90 . . . .( and that makes you about 30'ish ? right . . . .and also, tell sister Patience . . .that Gomer sez HEY ! )
Certainly looks like my industrial sized 30 in crystal ball was spot on in its pre prediction, it even being . . . . . sans photos.
Initially, using the small photos overall coverage I am first seeing a standard clip in line fuse being missing and also, a slow blow chemical fuse ( round reddish brown case ?) , located just above it at the 10 o'clock position is missing / being pulled from the board.
CIRCUITRY . . . . . BLOW BY BLOW RUNDOWN . . . .
Looks like the top left quadrant of this PCB is devoted to being a minor
STANDBY power supply*****
AC LINE power comes in from your fusing and initially encounters the paired grey resistors and a couple of
BLUE CY type ceramic disc capacitors. Then each leg of the AC goes into the phase opposed inductor windings of L200 choke . Then they need to feed AC into 4 discrete power diodes OR a packaged
Full Wave Bridge to create 350'ish DC for the quad set of main raw DC
BLACK E-cap cluster that you see there. It / they, are
NOT being visible to me on the supplied photos angle of coverage. Then, there is being another set of
BLUE CY type ceramic disc capacitors.
Next, the raw DC voltage is passing to the primary winding of the
YELLOW KYNAR insulated switch mode power transformer and the ends of that primary winding goes to the now BLOWN POWER FET's Drain being enclosed within the fractured IC202 case .
That then leaves you with the now blown open, BLUE 12 ohm metal film power resistor .
( OHM it out from either of its lead ends to a meter probe piercing the insulation,at the very center of its resistive body, to then , hopefully, see if an intact 1/2 of it remains reading 6 ohms . )
I sort of suspicion it to be connected in the final FETS Source link connection to power ground .
Taking an ohmmeter and placing a probe on its right lead and measuring with the other probe lead, to see if that is being of lowest resistance to a negative lead of the 4 E-capacitor cluster nearby, would confirm that .
OR if it is being connected to an E- capacitor + lead
I ??? think ??? that I am seeing a keying gap cut out, at the top of the IC so that just mentioned R214 resistor, has its left lead being connected to IC pin # 6.
Not that will help
UNTIL the IC number is known . . . and I was hoping that a top shard of that casing would be intact enough to let you make out a part number of a posssible TOP45--- or -----TNY264----or -----LNK406 on it.
I might guess that the board part number is being that paper tag of 75.475.522 stuck across the tops of the 3 gray cased caps.
You did not give the model number of your hob and the parts site below even wants your units serial number . . . initially.

Some how, you need to get that IC202's stamped on top part number.
Meaning a photo of same . . . on a good unit . . . . or you need to find a supplier that has one physically in hand that can be inspected.
OR if you do find that factory or supplier that has one that can be visually inspected, then YOU are e- mailing / phoning that person / supplier and presenting yourself as Holly Golightly, secretary of ABC appliance repair and are being tasked for finding a V-Zug replacement board for your serviceman.
HOWEVER he absolutely mandates that you check on the physical examining of the in stock board that he would be receiving.
Because, he has had problems with IC202 exploding on two of the last three boards that he has replaced in the past, thereby causing time and cost loss call backs for another replacement.
He says that there is being an upgrade to that IC202 circuitry . . .now, can you inspect your board and give you the numbers being on IC202's top.You forgot to ask him what they were . However, you can ask him, as he just radioed in, that he is enroute back to the shop now.
" The Numbers are then received" . . . . . .then you check them with the serviceman . . . . . he " says" NO . . . thats being one of the bad / problem boards . . . you then just say to the supplier . . . . . I'm sorry, but I'm going to have to find one of the upgraded boards.
