For the record, my PVR350 also started to drop audio - it was fine after a reboot and would then start recording mute soon after. This got progressively worse over a week or so.<br><br>I took the box apart to re-seat the card and noticed that the two 10v 680uF electrolytic capacitors on the card had 'mushroomed'. I de-soldered these and replaced with high-temp (105C) 1000uF 16v caps from maplin and all is now well. Not a single audio drop-out since...<br>
<br>The smoothing caps have a rated life of only 2000hrs at 105C. At the 40-50C inside my case, the caps lasted about 25000hrs during 3.5yrs use.<br><br>If you try this, note that it's a bit fiddly as there's a very small surface mount cap to avoid near the legs of the electrolytic caps on the underside of the PCB.<br>

The above is from a thread back in January before I subscribed to the list:<br>
<br>
<a href="http://www.gossamer-threads.com/lists/ivtv/users/37540?search_string=pvr-350%20dying;#37540" target="_blank">http://www.gossamer-threads.com/lists/ivtv/users/37540?search_string=pvr-350%20dying;#37540</a><br>
<br>
My PVR-350 is exhibiting the same problems. What was the outcome on the<br>
above? Should I buy a new tuner? I'm leaning towards a PVR-150 since I<br>
no longer use the TV-out of the 350, I'm assuming it's a decent<br>
replacement since I don't plan on moving to HD anytime soon?<br>
<br>
Thanks!<br>
