| Pioneer | Elite VSX-27TX | Pioneer Elite VSX-27TX. However, most of the time I can't get any sound. Now and then afer 15 to 20 minutes of leaving it on it comes to live. | There probably are some dry solder joints or bad cable connections in this amplifier.
Just switch on the amp, and gentley tap on the chassis with an isolated screwdriver.
If the sound "jumps" back on, there almost certainly is a bad solder joint / connection.
