Personal Anecdote

Similar to a few months ago, I encountered virtually the same situation with my TV.

After putting in a hard day’s work, I was ready to watch the next episode of my favorite series. 

But as soon as I pressed the power switch, a flashing red standby light appeared, which is something I never wanted to see.

To my dismay, I panicked. Here I was, having invested a fair amount of money in this television, and it was letting me down. It was very irritating, but I went through the usual diagnostic procedures: 

ensuring the power connection to the unit and cables, the ventilation opening was free of dust, and the unit was restarted.

Days later, I considered the remote. What do you know; the television worked again with the only change being the remote’s batteries. 

Such times teach us how little attention is paid to the easily available resources when fighting one’s technological affliction.
