Backlight powers off - Backlight is OK, capacitors have been replaced
This 40 inch Samsung TV was a dump find in 2013…replaced leaky capacitors and all was well until a month ago and the backlight turned off, but could hear the sound. Held a flashlight up to the LCD….it was still working. Capacitors had leaked onto power board again. Cleaned it up, ordered new capacitors. Worked fine for a couple of weeks, then the same symptom….working fine then no picture.
I took the back off and let it run that way. It stayed on longer, but eventually powered off.
I think the backlight itself is still OK and the backlight tubes are OK since there is no dimming….they are either on or off.
As I wasn’t too happy with the quality of the capacitors, I may order new, better ones. Anything else I should check on the power board?
