Thanks Aidan for the info. I assume both TVs have same model number.
It seems power supply board failure in both TV, one that powers up after few tries has got bad capacitors or devalued resistors issue and swapping the power board in TV will help to resolve the problem.
Once that TV fixed, take out the new power supply board and install it in other TV which is dead to see if it turns On then can search and order another power board for other TV.
Required power board is available (used) at following ebay link (please get the part number off of power board in TV to compare) or search/ google it for better price and stock info to order it, if you are working on it yourself...
