Check the on/ off switch contacts, they may be burning out. Replace the switch or try spraying some contact cleaner into the switch from the inside.

Element ELDFT406 shuts off by itself every 10-60 minutes


Ok, I am having the same issue. I just bought my tv - same model at the Target Black Friday sale. Can I ask, did yours make a low humming noise before you changed it out. I still am within my 30 day exchange policy, so I am thinking it would be wiser just to exchange it... but my concern is, would I get one with the same problem (or worse) in exchange?

Sound cuts off after no more than 10 minutes!


SOUNDS LIKE THE ANTI THEFT SYSTEM HAS SET ITSELF ON YOUR RADIO CAUSING RADIO TO SHUT OFF AFTER 10 MINUTES. THIS WAS DUE TO POWER FAILURE WHEN YOU DISCONNECTED BATTERY TO PUT NEW ONE IN. THIS IS COMMON. YOU MUST ENTER RADIO ALARM CODE FROM OWNERS MANUAL OR CONTACT DEALER TO GET CODE FOR YOUR VEHICLE. HOPE THIS HELPS!!

Hi have a Onkyo TX-SR601 after using it for a while it shuts down.


The problem could be bad solder connections on the main, or the audio outputs are breaking down when they get hot.

The machine runs for brief periods, then shuts itself off. If it is allowed to sit for several minutes, it runs again, then shuts itself off.


the motor is heating up to much and the cut out switch is kicking in. You need to check the the motor filter, and worse case you may need to new motor..
