That's either bad power board or bad main board.
Given the description it is very hard to say which of the two it is.
Frankly, considering you can get a new power board for $25 I think you should just go ahead and do it - it will cost less than bringing the TV to a repairman and as a repairman I can tell you they wouldn't have much better chance than you do...just shoot for a try and this will narrow it down to a single board.
I am not anyhow associated with the above seller. it is just the lowest I could find on eBay.
Hope this helps!

The fault is with its main power supply regulator section itself. One or more voltage rail is missing. Your TV need a through checkup. Seek tech assistance.
