DEAD - VERY DEAD.
L.O.L.
It looks like a 120pF/630V Polypropylene but can you give us an idea of its size.
More to the point - HOW has a 630V cap got into that state ?
Polyprops are usually pretty reliable unless they are overheated.

That sounds about right. The larger diameter is because of its high voltage rating.
Might be worth waiting to see if anyone has the schematics to confirm the value.

There isn't a C202

Purely from its voltage rating I would guess that its C001 - across the mains switch. I am guessing though.

I agree with ELVEE - my mistake polystyrene not polypropylene.
If you can ascertain where it is in the circuit we can offer a suggestion for a replacement.

I guess this would do as a replacement

How the hell did it get into that state.
You can use any 1% Polystyrene cap of 120pF in that position as long as the voltage rating is above the Vcc of the IC. I'd go for 63V just to be safe.

Here's one as an example.

How did that happen ? I managed to post a suggested replacement in your last post ?

You might find these guys more helpful with small quantities but this is only a 3% component not 1%

Easy enough bit to get but nothing on E-Bay this afternoon.
I've never known one to fail though. OK this one is cooked, but they normally fail very early in their life.
🙂
I meant the Rotel actually, sorry if it wasn't clear. There's no way a cap could fail in that location and it does just look like external burn marks tbh.
I wonder why he suspected it in the first place ?
I'm out of my league here but if the IC is suspect - I would start with the Xtal.
