This looks like a problem with the High Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.
In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,

The 9 flash error usually means an issue with one of the power supply boards in the TV. You can verify this by bypassing the shutdown. To do this with the set off and in the standby mode point the Sony remote at the TV and press these buttons in sequence within 5 seconds of each other, DISPLAY 5 VOLUME DOWN and then POWER. The set should turn on with no issues. Once it comes on there will be a diagnosis screen and the bottom entry on the screen should be ZCD. That entry should have a zero in the fail column. If it has anything besides zero then the power supply board is at fault. There are two power boards in this TV so I don't remember which one causes the issue whether its the G1 or G2 board. At this point if this is the issue then I would have a technician do the repair since replacing either board isn't that easy. Please take a few moments to rate my answer. Thank you....
