My speaker amp won't power on suddenly. Checked fuse and replaced it even though it was OK.
A quick look shows 2 large capacitors possibly bulging. See pic - are they bad and likely culprits for the lack of power since they are on the board the power goes to ?
Note : as you can probably tell I am not very knowledgeable when it comes to electronics

 

If capacitors are bulging or leaking, replace them. This does not guarantee that it will fix the problem.

Do these look like they are bulged ? I assume they should be completely flat across the top or is a slight concave shape normal ?

 

I cannot tell from the photos. I would be looking for a problem someplace else with proper test equipment.

 

Sometimes capacitors with a plastic cover over their top show some disformity over the years, but they still work absolutely fine.

I am not saying that is what is happening in your case. Therefore, to be absolutely sure, please follow @MrChips advice for a thorough investigation of the root cause of the problem.

As a general statement, these large high voltage reservoir capacitors fail much less frequently than the lower voltage capacitors at the output of the switching power supply. I would start my investigation by measuring the output of this power supply in both DC and AC (to see if there is excessive ripple) with a voltmeter and go from there.

 

I have thrown the amp out - I don't know how to fix it and not financially viable to pay someone as their bench fee to find the problem is more than I paid for this.
Thanks for the replies
