Other caps may be bad as well - but its a start.

Post good clear picture of the set with the back off and one of each board.
and a close up of the connector on the power supply that goes to the main board and the area on the back of the board (((where the power supply connects.))

EDIT Sorry just re read that - should say "where the inverter transformer is"

Check voltages from PSU board in standby and when working.

Check voltages from PSU board in standby and when
working.

voltages in standby 12.25v first 3 pins
GND 0.00V NEXT 3 pins
ADJ 3V

ON/OFF 1V


TV SWITCH ON 12.22V FIRST 3 pins

GND 0.01V NEXT 3 PINS

ADJ 0.03N

0N/OFF 4.37


and its a 8 pin plug going from power supply to mainboard

will put a picture of the power supply on

Board looks very sad - post a pic of the back so we can see what is burnt
Was the set yours when it last worked? some history of how it failed might help.
Assume there is no flash at all from the ccfls
