Hello, and sorry you're having problems. We are now connected on this website- which saves you money over having a Tech come to your home, and in many cases we can fix the problem you're having. In other cases, these things do require additional parts to fix. But I can help you with that as well.
What you're experiencing is a hardware failure occurring in this set- which is something we see commonly. What causes the set to need to be power cycled repeatedly in order to come on, are weak/failing capacitors on the power supply inside of the TV. Once they are cycled over and over, they generally come bac into the spec and then the TV is find until the next time it's shut off.
In order to fix this issue the power supply board in the TV needs to be replaced, which is on average a $200 repair on this set. Depending on how long you've owned it for- that same money may be better spent towards replacement versus repairs (a brand new 32" LED TV can be purchased for around $200 these days). However if you'd like you can use the link below to locate a shop in your area:
I'm sorry for the bad news on this one and I wish there were a quick fix.
