Good Luck

This classic a HV supply problem. The possible culpits are deffective flyback transformer, Hv rectifier or the horizontal output transistor
SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.
If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
