How to fix blown Rigol scope probe RP3300A?

I applied a 450V pulse to the probe with probably a 1uS rise time and it was just a bit much... Now with the test square wave that comes out of the front of the scope it only shows about 2/3 it's actual amplitude and the rising and falling edges are very rounded. It does get to the final (lowish) voltage though. Swapped channels and the problem follows the probe.  There's only 2 resistors, a cap and a trimmer. What is most likely bad, the upper divider resistor? The upper divider resistor is labeled "01A" and the lower "16A". What values would that mean?

More info:-
R2 measures 100.0 ohms, a reasonable figure maybe.
R1 measures 142.6 ohms - a bit sus. I would have thought perhaps 9.0 megs.

Edit -> seems the resistor values are correct at 100 and 143 ohms.
Maybe there is another resistor in the probe end, not the connector end as in the picture.

Okay. The good probe measures 9 megs end to end and the bad one 15.5 megs from the BNC connector to the blob of solder on the left side of the pcb. There does not appear to be any way to get the probe apart. If not then it's all over.

There's always a way to take something apart. The difficult bit is doing so in a way that allows you to put it back together.

You could always resort to a hammer for the first operation and duck tape for the second.

Did you repair it?

Nah.  For the price of a new one I bought two x10 probes and two x100 1kV probes, all 100MHz I think. The remaining original one is kept aside for special purposes. Maybe I'll get a new one one day, for AUD$65.
