TV/VCR/Stereo Troubleshooting/Digital Labs 7 " Portable LCD-TV


I am not getting any power to the TV from the adapter.  I used several different outlets and nothing.
It is a model DT191SA.

What good be wrong.

Here is a source for the power adapter that is only $15 plus shipping:®-Adapter-Digital-DT191SA-Charger/dp/B00AI1B27Q

It may be worth just getting a new adapter rather than trying to repair the one you have.

If you do want to troubleshoot the adapter you have you may want to acquire a vom (Volt-Ohm-Meter) to test the voltage output from the adapter; this way you can learn if the adapter is putting any voltage or not.  You can buy a simple voltmeter from Walmart, Home Depot or Lowes for under $10.

Hope this will help you with a solution.
