Hi all,
Ok. Where do I start.
Last year my trusty A/F just stopped working after cooking a meal. There was no sound, it turned off as normal.
Next day, it wouldn't turn on!
On opening It I found that a 47Ω 2W R1 had literally crumbled to bits. The one in the middle.
Ah ha, I thought, a blown Fuse. Easy peezy...! Off to JayCar I plodded.
They only had 2x 23Ω 1W (I think from memory). I then 'made' this R1 47Ω 2W.
The A/F still had no power. And then a DOH! moment and I tested the other fuse R2 and that had gone, finding hairline cracks in it! Jaycar only had a 47Ω 5W 'block' left.
Then I noticed that C6 - 10uf 50v had gone. J/C only had a 63v, so that was ok.
When I had finished, I plugged it in with wide hopeful pride, and BANG! Smoke drifting up from underneath the pcb.
With a lump in my throat I turned it over to see that D1 had blown itself up!
I have managed to purchase the Correct Fuses/R's bought 5 of them!
Thinking that the IC might have gone due to the bang, I got two of those!
This is the website that I found after I replaced the R's and it still wasn't working.
As it is, the 'dual' R's are ok. The white block R2 is gone and C6 is gone. Plus that D1

New Fuse R's
New IC's and Fuse R's:
I'm off to J/C in a bit and will grab a few more C6's.
Thanks people
