Samsung HLN617WX/XAC 61" projection TV Mfg Apr 2003 Won't go on.
According to the schematic, the Pwr PCB provides 5v to the Main PCB. When the ON button is pressed, or the remote tells the set to turn on, 5v is sent BACK to the Pwr PCB which picks up relay RL801S, which activates the 380v circuit, and shoots the 380v to the ballast, to ignite the lamp.
The lamp is not igniting. No 380vdc is going to the ballast board. The Main PCB is not returning the 5v to turn the Pwr PCB on...
Can anyone help me with this?
