Integra DHC 80.1 not covered but DIY repair successful
I have an Integra DHC 80.1 that I bought in March of 2010. Within a year of buying it, I could no longer install firmware updates (known problem with the HDMI board) but as of recent, I found I would not have any audio when first powering the unit up each day and would have to go through a power-up/power-down/power-up cycle to get audio. With the wife rightfully frustrated, today it got to the point where the audio was completely distorted. My current plan is to replace the pre-amp with anything other than an Onkyo/Integra product because I don't feel that a $2.5K pre-amp should fail within the first year or decay to disfunction ever...
All of that said, I decided to research it a bit and it seems there are two common problems - one being poor quality capacitors and the other being cold-solder joints on a DSP that eventually fail due to heat stress. In the image below, I circled the DSP I fixed in red.
I don't own a reflow station so I borrowed my wife's blow dryer and set it to maximum heat, maximum air and rotated it over the chip for 4 minutes. I gently pushed on the chip a couple times using pliers to try to reseat it and re-applied high heat for another 5 minutes. I let it cool, plugged it in and it is working perfectly (hard to believe). So apparently my unit suffered from a cold-solder SMD joint that I was able to fix by heating the chip up sufficiently to reflow the solder joint. This DIY repair will give me more than enough time to research a high-quality replacement but I will never buy or recommend Onkyo or Integra to anyone ever - inexcusably cheap electronics!
