The no sound is common issue with Yamaha RX series amplifiers. This issue is caused by a faulty DSP chip. If the chip does not work at all you will need a new chip. But most likely the chip just has a bad connection.
sympton: usually you get sound once the chip is warmed up
Reflowing the chip will fix the issue and you will get sound back.
This instruction will fix all the RX series amplifiers with the DSP chip.
The thing in the tube is soldering flux. It helps to make the solder tin flow. I have a tube of some cheap stuff made in china. The brand is Hanwuyou advanced metals tech inc. Flux type NC-559-ASM. Almost any soldering flux in a tube can be used. The best would be Amtech 559 rosin flux.
For cleaning I used IPA (iso propral alcohol), if you do not have some you can use zippo petrol or any other electronic cleaner.
