I picked up a Samsung LN40B500P3F for free. It turns on for a few seconds, but then the backlight dies. It will come on again after about 5 seconds and stay on for about a second. It repeats this a few times, and then eventually the backlight stays off.
As far as I can tell the rest of the TV is working good, it is only the backlight that won't stay running.
I see there are numerous posts here about this model or similar Samsung LCDs, but it seems like most of them are completely dead and not the same issue as this one.
I get 392 volts DC across the 2 big capacitors at all times when the TV is on, even after the backlight dies that reading does not change.
Can someone point me in the right direction on what I should test to narrow down the problem please?
