First try to reset the TV by holding on the menu and switching on. if not switch off and open.
Lets imagine that there is fault associated only with a damage during the transit. So lets us start with the power plug and the connection to the front end section of the TV.
Use a multimeter to check on the continuity of the power plug to the main board. If this seems Ok switch the mains and see if the supply comes to the main board.
The fault that needs to be checked is to look for some broken or damaged board. so look carefully if there is any crack on set ,if so bridge the lines using a soldering iron.
Now check if any connectors have come out of socket.if so tighten all the sockets in the boards.
Now the next point of check is to see if the power is coming to the board , then the secondary circuit of the SMPS to the microprocessor board. If the supply is coming inthere should be a display in the front panel.Try to replace the battery in the remote and switch on.
The fault can only be in any of these points as the set had worrked before the transit. so take you time and use the logic of seeing that the power reaches out to all boards.

Sounds like ( pardon the pun!) one of the TVs chops on the circuit board are gone. Costly enough repair, how old is the T.V? Is it under warranty?

RCA 36' tube tv won't turn on


possible that a fuse blew while transferring tv, most like to happen despite care in handling if tv was on for a while, kind of like moving a light bulb that is hot and suddenly filament breaks when you move the bulb slightly. Other than that I'd say it's a good time to get a new tv just in time too for the digital transition.

fot the most part, you have solved your problem (pow bd), The main bd may also need to be replaced as well. The is a signal upon powering up the system. the pow bd communicates with the signal board. The signal bd, also is responsible for ALL of your additional I/O lines. Between the two of these, + a firmware update, i think the tv will be just fine.
