Hello,
a little presentation. : Stephane from France. I have been loving to repair stuff for ages but I don’t know and understand much on electronics. I have been following the thread about the Yamaha p95 (having a P120 with the exact same issue but not the same boards and components, I still haven’t had the courage to unsolder components to test them)
but yesterday my Philips steam iron GC9642 stopped working while using it. just died so after a small troubleshooting I opened it and found 2 burned resistors (3035 and 3037). I replaced them but still no life at all on my steam iron. As I feared, the burned resistors were not the reason of the failure but a consequence of something else which is not visible…
i really don’t know how to read technical schematics.
before buying the whole board I wanted to see if anybody had any issue like this one or any other idea

thanks and sorry for my not so good technical English

 

Bonjour Stephane. Your English is excellent. Welcome to AAC!
Those two resistors are in a low-voltage (3.3V) section of the circuit and are not designed to carry more than a few mA of current. The only reason I can see for them burning up is if mains voltage somehow reached them and caused excessive current through them. If it did, then it is likely the MCU (Atmel-XMEGA IC) has been damaged too :-(.

 

Thanks for your fast answer.
Doesn’t look too good then ! I will order a new board then, the lazy way

 

Hi,
As a matter of interest, can you determine what Header 3 connects to?
If there is a problem upstream from Header 3, it's likely to kill your new board.
Good luck.............

 

Good point. I was wondering that too… will look into that tomorrow
