Power up problem

I'm assuming that it repeats the Sirius logo and beep at a periodic rate and never loads up to the tuner interface. My radio suffered the same fate. Unfortunately, it is dead and out of warranty.

 

Sanyo only offers a 1 year warranty. If your radio is still covered, they will replace it. Otherwise, you're SOL and will have to buy a new radio.

 

I do not recommend Sanyo.

i found holding down the menu button when the sirius logo is displayed, then turn it off and then on again-it seems it will run as normal(exept my antenna signal is sooooo **** it still doesnt work....Sanyo sux

This definitely appears to be a heat issue.

I've spoken with Sanyo Service twice regarding this issue. The first time I was told that the solution was to power the unit off for 1 hour, and that it was something that could be serviced. The second time I called, when I asked what the service procedure was, I was told they don't know what causes the problem. Hmm...

In any case, I managed to get the case open. After removing the faceplate, take out the four screws in the front. Using a small screwdriver / pry tool, pop the case off at the FM out port. BE CAREFUL! The FM transmitter is soldered to the front of the case, so don't move it around too much or you'll lose that nice, strong FM transmitter. Once you locate the connection for the FM transmitter (a small wire), you can open the case such that the two halves lay next to one another.

Once inside, you'll see another metal box that contains what I believe is the main chipset (Agere). More screws here. Once you take the screws out, you can lift off the metal case. Here's where I suspect the problem lies. There is a cheap heatsink pad in here that, I suspect, over the years has degraded to the point where it no longer conducts well. I cleaned the top of the chip with IPA and put some new thermal compound inside. I have not yet removed the pad as I did not have an appropriate thickness piece of something else that I could use to replace it. I then reversed the process to put the case together.

My radio is still funny, but it seems to work better now. Since the weather is now cooler, when I have problems with it, I hold it out the window or in front of the air conditioner and it comes back after a couple of minutes. I also disabled the blue LEDs so that the heating inside the unit is minimized. It conceivable that there's a bad solder somewhere, but I didn't see anything that stood out. If I continue to have issues, I plan to go back in at somepont and remove the pad, replacing it with something else (copper foil? another pad?), but until then, I'm still in business, even if somewhat diminished capability. I've got a lifetime subscription that I'm fighting to avoid a transfer on, at least for a little while...

unit will beep on and off showing sirius logo but will not power up to a stations
