It means that there is a horizontal sweep or High voltage circuit falure. It is a high voltage circuit and only a trained tech should attempt to repair these sets. A TV set is not a place to be experimenting inside of.

The problem you have is with the G1 board. The 17 volts is not supplied. Do you have a multimeter and know how to trouble shott following a service manual schematic? if not call a pro to assist you as this could be the G1 board, but to be sure, you will need to troubleshoot and check some voltages and follow circuit flow using a schematic diagram.If you can then let me know..

A 9 flash code is defined as a zero cross failure, basically a power supply fault. It is usually caused by the failure of one or two diodes on the G board D6301 or D6116. D6116 is 871908197 and D6301 is 650056721. If you can get them and are handy with a soldering iron, you can probably replace them. Be sure the set is unplugged and use care when installing them, as high voltages exist in the set even after it is unplugged. If this answer is to your liking, please be sure to rate it. Thanks! Also, a good confirmation of this is to turn the set on using the following error code display method. With the original remote, press the following buttons:
The set will usually turn on this way if the diodes have failed
