It could be the power supply or the short circuits in the backlight inverter board tah caused the power supply to go into the shutdown mode. Those are the two main things to check.

    Does the back-light inverter board let the power light come on and flash off then back on once every two minutes no sound or picture new power supply installed. This is the same problem before new power supply.

AUTOMATIC SCREEN BLACKOUT after power on


The power supply is not latching. This is common on those machines when they have bad capacitors. You can change the whole power supply out if you are versed in electronic disassembly.

It seems to be a PSU (Power Supply Unit) problem. When you unplug it and replug, the screen comes on for a moment. That means that the capacitor does not hold charge for long. Open the back and look for bulged or burst capacitors on the module where the power cord meets inside. Replace the whole module if you can not replace the capacitor with exactly the same specs.

Sanyo ce32ldy1b lcd 160gb black screen with sound


It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!
