I tried to pry that heat sink off to look, but I've not been able to, even after cutting away the glue and applying a fair bit of force.

Nor does the capactor get hot next to it (at least not quickly anyways).

& yeah at some point I'll flash it. It's been reset and that didn't make a difference (I went through all the steps with Phillips).

Screws being too long might make sense yeah - as for the capacitors, not 100% where the sound chip even is? Nothing looks obviously wrong to me, but not sure where I should look. Have attached pics of the inside.

Is it the CapXon 470? (it's measuring 430 ohm)...

Hello,

I've got a really strange issue with the speakers on my Philips 43PUS7506/12. It makes this awful loud buzzing now. It happened after it was attempted to be wall mounted - I think the back got squeezed and something broke.
I thought maybe the speakers got damaged, so I replaced them - no dice.[LIST][*]Using the internal speakers, it always happens.[*]Using the headphone jack, it never happens.[*]Using the digital/optical out with a soundbar - it happens after about 2h/movie runtime - it's never as drastic, it just pops in and out, but I didn't want it to damage the sound...

Hello,

Amateur here, I hate waste and love to try and repair things myself. Hoping to get some help ...
