If your Samsung LCD TV isn't powering on, start by checking the internal cable connections. It's possible the cables are improperly connected, or the Main Board or SMPS is not functioning. Also, check the fuses of each part and the output voltage of SMPS. If problems persist, the Main Board may need replacement.
What to do if my Samsung LE19C45 LCD TV has no video (analog PC signal)?
If you're not getting any video signal on your Samsung LCD TV when using an analog PC signal, the PC source should be checked first. This issue may arise from a disconnected LVDS cable between the Main Board and the Panel. Also, check CN902 and the PC cable.
