Question about Teac AG-D8900 Receiver
I have had my Teac for several years; however, within the first few months I blew something in the amp. I had lost the receipt and was too cheap to pay for repairs so I purchased some fuses and tried to fix it myself with no progress. Today I was looking through my electronics and thought I would give it a try. I plugged it in and what do you know it decided to work! I was stoked. I plays through the sub perfectly, but there is still some issue with the amp because it puts of a static noise while playing sound. Any ideas?

From what you have described, I am thinking that you had to replace some fuses? If so, the amplifier circuit may have a problem. Figuring out what that problem is will take some good electronic troubleshooting skills.
When the fuses got blown, how was the unit being used? Was it being played at a very loud volume?
Does the static come in all the channels and at all times or does the static happen in only one channel?
This problem of yours can have many different causes.
You seem to be very adventerous, willing to poke around in your receiver a bit, so I will help you more if you can get me answers to these few questions.
Please be aware, you can cause many more problems trying to fix these things if you are not experienced with them. There is also 120 volts of A/C voltage that can cause serious shock or even death if touched, so be careful.
There are a couple of things at a bare minimum you need to have to troubleshoot electronics.
You will need to have a multimeter, the troubleshooting will be much easier and faster. If you do not have one, the troubleshooting will go very slowly and will most likely end before finding the actual problem. The multimeter will be used to measure voltage and resistance, and it is vital to finding the problem. You will also need a soldering iron, solder, and solder wick (if you need to remove any solder).
Most of the parts that are used in these units are available at electronic parts stores on the internet. If you have a problem with the DSP board in this, you may not be able to get the parts needed and may not even be able to figure out what the problem is. They are very difficult to troubleshoot. I have been repairing car and home audio equipment for nearly 18 years and have become very proficient with them. But without having it in front of me, it will be a challenge. I am up for it, and I have a feeling you will be to.
Let me know,
