Check your power supply's 15 Volt line. It supplies voltage to the circuits that generate the 10 blink code. No or low voltage and you'll get the 10 blink code. You have to turn the TV on to get that 15 volts to turn on. The power supply board should have that listed on one of the plugs I believe. The P6 plug is on the opposite corner of the AC power plug, look for that. You should see 15V and GND on that plug. With a voltmeter set to DC volts, you should read 15 Volts when it's turned on.
