You need to check several voltages

(2)FLAC1 and FLAC2
(3)drive signals to FL needs a digital storage oscilloscope to observe waveform. Or replace chip directly.
This is a full picture.

"Tone Control is not working when I push the button but the light will go on and off." Download TX8511 service manual. Tone control circuit involving balance, bass and treble circuit is defective. Check circled componets or replace them all. If replacing them all, balance circuit should also be replaced.

"I accidentally touched a speaker wire to the metal spikes on the bottom of my speaker. " This action makes +B voltage (positive voltage) short to ground. You may assume 2 power transistors mounted on a large heat sink are defective. Now try to remenber which speaker terminals was accidentially shorted. Then check this terminal or you should check all power transistors mounted on the heat sink, by measuring the collector and emitter resistance. Normal value is Mega ohms and all white 3 pins resistor with 0.22ohm should also be checked if they are open( infinity resistance).I have tried to reset it several times to no avail. Of course, due to defective power transistors. Is my receiver done? Yes. I wrote detailed troubleshooting steps used in onkyo service dept. a year ago, just find it out in my answers.210cda21-872d-438d-949c-2196ccf76712.jpg
