Q: How do I stop my MacBook turning off my TV monitor automatically

Hope you can help me

 

When I connect my MacBook (2015 running Os X Capitan) to my TV (Panasonic Viera CX-400) using HDMI it displays the screen as it has always done but then the TV shuts itself down after 20-40 seconds. It doesn't just go blank or anything it shuts itself down.

 

It has worked fine over the last week since I got the TV (It's new), I haven't changed any settings on either device (That I'm aware of) and other HDMI inputs such as XBOX and normal TV are working fine.

 

Any ideas of what could be happening?

 

(I have tried restarts, have unplugged the TV, used different HDMI slots)

MacBook, OS X El Capitan (10.11.2), .

    Many TVs have an setting that turns them off if no video signal has been received for a set interval of time. Check for that, if so, you may be able to turn off the feature.

    Hi,

     

    Tried but no change. Like I said, it happens after 20 seconds, the TV setting is at 4 hours. Any other ideas?

    There may be a small possibility of an issue involving the TV set itself; however

    unlikely. Not sure how to test the monitor apart from the MacBook to be certain

    if the monitor may or may not be at fault.

     

    One suggestion may be to try another brand of TV monitor, or a different sample

    of the brand/model you have now. Helpful if the store allows returns for refund or

    has a fair exchange policy, one that could help you in troubleshooting this issue.

     

    Troubleshooting may require the use of different adapters, check cables, connectors

    & maybe see if different television monitor device exhibits no similar characteristics.

     

    Not sure what else to suggest.

    Good luck !

    Thank you K Shaffer. I will bring it to another monitor tomorrow, and check that possibility out.

    Sometimes the adapters also may be causing some kind of feedback to the

    attached peripheral device, be it a TV or something else; maybe those need

    be looked over carefully. Hard to see an 'internal defect' if one exists, though.

     

    Hopefully the problem is simple...
