Take a look inside see if the amp uses transistors or an IC. If it uses transitors you can put a Ohm meter accross the leads (no power on) If it reads 0 (digital meter) or the pointer swings full over on the leads of any the transistors it's blown. If an IC then the thing might look damaged.

No audio from main speakon outputs A and B


Hi, I think in most amps switching to bridge mode simply means the amp supplies its total power through the left channel only. It's the best way to use all of your amp's power but nothing comes out of the right channel. Having speakers connected to both channels would simply mean that only the Left channel works, it would not blow it. Some amps have the speakers wired to binding posts and this varies according to whether you want mono, stereo or bridged. I can't help with the power board sorry

No sub woofer output or very little


Your sub amplifier is detecting an overdrive condition and reducing volume to prevent the output stage from burning up. When reduced volume doesn't work, output is cut completely for 10 minutes until things have cooled down.

Roland KC-500 has power but no sound.


You need to determine if the power is getting to the audio amp section. For instance with the volume full up is it humming etc?
As a 'rule' it's unlikely that both left and right channels will fail at the same time (unless you have done something silly with the amp) you are looking for something that is common to both channels. Which is why the power section is first suspect. The exception to the rule (above) is where amps use say an IC power amp for both channels. You will find this IC on the big heat sink. Check whatever is on that anyway for damage or burning.
The only other area could be the pre-amp part. Again this could be a single IC controling both channels, so it's failure could cause a loss of sound. By the way if you can hear music/sound coming through when you put it up to full volume the pre-amp will be generaly good.

Hi i have an audio source 300 watt amp with a&b speaker outputs. the problem is that no sound comes from the left side outputs a or b. the right side works fine thank you mike


You have a blown channel. If you are experienced with electronics repair, use the right channel to assist in diagnosing the left. Both channels should be efectively identical. In most cases, the defective parts are the output transistors. You should be able to A/B the output amp sections.

Let me know if you need further assistance.

Reduced audio output from right channel


Try lightly tapping on chassis to see if you can get audio to cut on or off with vibration if you can most likely cause is bad solder connections. This unit is well known for poor solder connections especially around poweramp driver IC's IC701, IC501. Also Electrolytic Capacitors in unit have fluid in them and heat Evaporates the fluid causing them to not operate properly over time . Caps that usually go bad are around parts that run hot like Power amp drivers
Just a couple likely suspects.
Try unplugging overnight to give unit a Good Reset also double check all setup settings.
If you need service manual I may be able to get you one

Sound gone


disconnect everything in the back of the unit. reconnect only the cd to the imputs. also,just to be sure, disconnect all speakers(label them). fire it up,play a CD, connect the speakers 1 at a time. If the 1st works you have hope ,if not, try each channel individualy.The one that reduces volume is the problem-maybe shorted cable, bad speaker,or , God forbid-Bad amp Channel. good luck

No right channel output


Feed the amp with the left channel preamp to the right channel input on amp and check output. If you get output from amp then pre amp nedds to be checked out if still no output then amp is suspect. Randy
