It might be the power supply in the TV itself. Our 32" Hitachi went some years back and I promptly 
went out and bought what looked like a good enough replacement, a 32" Samsung. Unfortunately, it was 
a lemon, although 'good enough' to make do.

I did some research on the Internet and found a supplier for the PSU card; as they usually supplied 
trades they wanted to know if I was capable of doing the replacement, I was. It came in the post, I 
unscrewed the old card and screwed in the new card, job done!

5+ years later, we're still using the Hitachi and it shows no signs of failing. No so-called 'smart 
TV' for us, thank you!

It does require you to take the back off the TV and look at the boards within. I believe you can 
even find repair documentation on-line these days.
