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!!

Have power but no sound or picture


Do you have high voltage? Check by turning up one of the screen controls to see if you have retrace lines.(pinstripe diagonal lines across the screen) If present turn the screen control back down until the lines just disappear. Check diodes 6003, 6012, 6025, and resistor 3669. If you don`t get a retrace line by turning up the one of the screen controls, check for missing voltages or shorted components in the horizontal output and power supply circuits. Note: Philips TV`s can be tricky even for experienced technicians. Good luck
