My TV is taking up to an hour to turn on. I can hit the power over and over and it blinks on really quick and then back off. Most of the time it turns on after trying for 45 minutes. What could be wrong with my TV?

So many things. I'm not an expert in this field, but my husband is. I would suggest just replacing your TV. It would likely cost more to repair it than it's worth.

What is the make and model of the TV?
