Mend Panasonic TX-W28R4DP Tv Switch Standby

Panasonic TV will not switch on from standby?

My TV (Panasonic TX-W28R4DP) tries to switch on from standby but fails to generate any significant secondary voltages. It makes 10 clicks and then stops. A correct standby voltage is present. How can I tell where the short circuit is likely to be? What are the characteristics of a line transformer short? I have the circuit diagram for the TV.

Checked Q551 and it was faulty. Replaced it with a BU2520AF as I could not get the kit quickly. Its all working fine now.
Very grateful to Cobweb for the excellent advice.

Check line output transistor Q551 if faulty fit kit part number TZS9EK001 (change BU2508AXLB to 2SD1577LB ).

A less common cause is IC1103 EAROM failure.
