That depends on the tv - for some brands/models the power board is the one that holds the circuits powering the screen - but generally yes.

Power 48v check


Hi
Either the power supply is
not generating a proper 48
Volts or the controller board
is not detecting a 48 Volt
output from the power
supply board.

1. Make sure the power supply
board is correctly connected to
the controller board.
2. Power on the printer. If the
message appears, do the power
supply operational check (page
195). If the power supply fails the
check, replace it. If it passes the
check, go to the next step.
3. Power on the printer. If the
message appears, replace the
controller board. Record the
message and return it with the
defective board.

Morning, My Panasonic Viera TH-42PZ70B TV will not start up the red led is flash 7 times.


Either there is problem in your power supply or main board. There are many SMPS on the power supply board. First check the voltages coming out of the power supply & supplying to the main board. The voltages are printed on the power supply board. The top one is power supply & bottom one is main board.

Will not power up. Tested from plug to power board. Power does not leave power board from any terminals.


The power supply board could very well be defective. I would also check the Zsus board and the Xsus boards. If either of these boards fail it could also cause the power supply board to fail.
You can unplug the connectors to the zsus board at the power supply and try to turn the set on. If it does turn on, the power supply board is ok. If not, the power supply is bad. If the power supply board is ok, undo the plug connectors that power the Xsus board and hook up the plug connectors to the Zsus board. Turn the set an and see if it stays on or shuts down. Part numbers should be on the boards. Zenith is really LG Corp. Their customer support number is 1800-243-0000.
Hope this helps,
Steve
