Screen went black while watching, now ony have sound


Look at the venting grills, you should see whit lights inside the set. If not, the backlight inverter board may have gone out or the power supply supplying the power to the inverter board may have gone out. Those are the two places to look first. It may have bad capacitors in the power supply.
