Memorex MT1194 CRT TV shuts off after exactly 15 minutes Can't Post

I have a Memorex MT1194 that shuts off after exactly 15 minutes - I believe this is a safety feature to turn the tv off when not receiving an input signal?

Does anyone have a solution for this?

I have tried all options in the normal menu and the service menu, and couldn't find any info on this in the service manual apart from a table showing that it has the "Auto Shut off" Feature and a sleep timer -

I did turn the sleep timer off and that was not the issue

Have you tried actually inputting a proper signal and switching input to that?

Yes the issue is I am sending an external signal to the yokes and the flyback outputs are going to a dummy yoke. I am looking for a solution that doesnít require an extra external video input, such as bypassing the shut off circuit or feeding a signal from the tv circuit board to imitate a video signal. I may add an IR transmitter Internally and flip the Ir receiver around, then send a volume up signal every 14 minutes to reset the timer, but was looking for a simpler solution.

Thanks!

I'd suggest using Menu instead of Volume Up so you won't have to lower the volume every 1.5 hours.Cool

I disconnected the speakers as Iím not using them either👍🏻
One initial thought was just to short out the volume button, but the power button doesnít work if any other buttons are depressed. So I may add a relay that shorts the volume button when the tv is on
