Hello, My name is XXXXX XXXXX I will be glad to assist you.
Do you have access to a cell phone camera, or digital camera?
What we need to do is view the tip of the remote through the viewfinder of a digital camera and press the power button several times. You should see a bright flash of light each time you press power.
Let me know if this occurs.
Okay, then the remote is fine and the problem is in the TV itself.
You stated that the TV has a hard time coming on even when you press the power button on the TV correct?
Thanks for the reply.
This indicates a component that is failing in the TV. It is most likely an intermittent short on the power board inside the set.
Do you have any experience, or are you comfortable with removing the rear panel of the set and visually inspecting the electronics?
That makes sense. It's likely the capacitors on the power board. The hardest ting for them once starting to fail is the initial charge when you turn the set on. Once they hold a charge they will typically be just fine until the set is powered down again. The thing is, it will take longer and longer for the set to turn on until it simply does not anymore.
To have these replaced typically costs around $200 USD, or for a new power supply would be closer to $400 USD. I would recommend taking the set to a TV repairman and having them replace the capacitors in the set.
In many cases (with almost all electronics), the cost of raw parts and labor is much more expensive than purchasing a new unit. This is mostly because the labor is intensive and time consuming, and the tech will not make any money if he charges less.
I'm sorry to be the bearer of bad news, but you may simply want to use the set until it fails completely and then purchase new.
