Question about Audiovox FPE3000 30 in. HD-Ready LCD Television
30" Flat Panel LCD TV
When I turned the TV on this morning there is no picture but there is sound. THe AUDIOVOX logo screen does not appear when the TV is turned on and the manual volume and chchannel buttons do not function although the remote does.
This can be a Power supply failure- some of the filter caps could cooked dry and the yellow glue they use in this power supply turns conductive where it turns dark brown. You can unsolder the devices and feet on the heatsinks and remove them along with the stand-up driver board. Change some of the filter caps-1000u/16V, 470u/16V, 47u/50V, 10u/50V. Scrape and pick off the brown glue from all devices. Removed the fan and found the bearing was seized in it. Power supply will now run properly with the defect fan unplugged.

The first thing that comes to mind is that the brightness and contrast or turned all the way down. See if you can't turn them up. Otherwise it may be the backlight inverter or backlight itself. Most likely the inverter, sometimes you can tell by looking really close to the screen, if you can still see a faint image then the inverter needs to be replaced. Probably a job for a technician but that depends how comfortable you feel opening up the TV and ordering parts online.
