This TV would go through the process of turning on but there was no backlight nor picture. The front led would flash a few times and then go out.
All voltages tested good coming from the power supply but the main board did not appear to be sending the BL_ON (backlight on) signal. When I disconnected the cable between the power supply and main board, the backlight came on.
Researching on badcaps, the main board appeared to require replacement. The part number was 96-14917A. I was able to find only one used board on ebay with part BN96-15158A. According to Shopjimmy, the board was one of many direct substitutes.
With the new board installed, the TV powered up with a picture.
Since the capacitors are all crappy Samwa, I proactively replaced them. Values for BN44-00338B are as follows.
CM858, CM859 – 1000uF/25V
CM853, CM854, CB851 – 2200uF/10V
CM851, CM852 – 1000uF/35V
CM808 – 18nF/630VDC polypropylene capacitor is also a common failure. Digikey substitute part is 495-7139-ND.
