Why is LCD TV backlight flashing?
Samsung LN-T4065F LCD TV 40"
The TV is 10 years old and has 5700 viewing hours.
The backlight is flashing on and off at a rate of about 3 times/sec. You can see a video of it here: https://www.dropbox.com/s/q7ngflkituz774...
This used to happen periodically then go away overnight. Now it's not going away.
How can I debug if this is an inverter problem? I have a multi-meter. Or should I just buy the $17 inverter and hope for the best?
