A customer brought in 19 inch Led television for check up, complaint was the television was not able to power up.
It was attempting then shut down in cycles, since it was using power adapter I tested the output from the adapter power supply and I got 12.44 vdc.
This looks okay according to the printed output on the adapter body.
So now I was ready to go the next level, opening the television and do further troubleshooting.
But before that I decided to swap the power adapter with the one I use in the shop for testing television in case the owner forgot to bring it along.
After powering the television I was surprised to see the TV has picked up and now working perfectly.
With this I concluded the problem was on the power adapter, but did I not get 12.44 Vdc?
