Sansui 18" flat screen, built in 2010.

Took a chance on troubleshooting a low hours set.
Upon powering up the set, the display stays lit for only about 20 seconds. In a dark room, you can see an image present. I checked the electrolytics in the power supply and subbed a few. Same results.
I think it has a fluorescent light source.
The power supply is available on the E-place, for around $30, plus shipping.
Trying to chose the best route.
