What is the cleanup process for post reflow on a PLCC84 package?
I'm worried about left over flux under the chip etc.


Spray it all out with acetone/alcohol?

I need help with my Harman AVR 247 receiver.

It shut down by itself one day. The sound volume just dropped and it shut off.

The standby light is on (orange) power on and the power light goes blue, nothing on screen, and then after 10 seconds or so shuts off to orange standby.

I found youtube video mentioning to replace a few caps near power supply. That didn't help. I replaced them. No change and they weren't bad except for one.

I was wondering if anybody has immediate knowledge on this type issue and repair for this model. I realize...

Re: Is this cap good or bad



Thanks for your support everyone.

I did replace it. Also this bad one was slightly bulging.

They combined series for this one in the chart. When I look for 470 35v the size isn't there but it's below. 15x31.5mm

I will ask in a separate thread for help or if there is virtual services offered.

I measured with this device I have and I'm trying to understand if it's good or bad.,
