Blu-Ray connection to TV

[BoDawg226]

Just purchased a 2005 Alpine. Prior owner moved the TV and put it on hydraulics so it will lower into cabinet. New TCL Roku TV. Connected to surround sound and a Blu-Ray player. Only hooked up to 120 (max 20 amp) at the moment. The movie will play for varying times - from 20 minutes to an hour - and both the TV and the Blu-Ray lose power. Then have a hard time connecting the Blu-Ray back to the TV (says it is unable to find the BLu-Ray). The AV Receiver usually stays on (odd). Anyone have an idea why this is happening? Not enough power? I'm no techie so would be glad to know what anyone thinks.

Preface this with I'm not 100% sure but - If your coach is same as mine you have a Surge Guard power protector/transfer switch inside the storage bay. One thing this device does is monitor the quality of the shore power and it will temporarily shut the power off if for instance the voltage drops out of limits. I have seen the same symptoms as you when plugged into 120v 20amp with an extension cord. Some electronic devices when they loose power do not turn back on when the power is restored and some do and this could be why the AV receiver seems to stay on and the TV and Blu-Ray do not. Fire up your generator and see if the problem goes away.
You should put your coach make, model, year in your signature line and you will get better and more useful answers. Alpines are a bit different than other motor homes and it will save you having to remember to put it into every question you post and more so keep you from following some well intentioned but bad advice.
