Audiovox FPE3000 turned off sponataneously and will not turn back on
My AVox FPE3000 30" LCD TV turned off on it's own and will not turn back on. When the power button ispressed (on remote or on the top) the red standby light goes off but the green on light does not light and the unit does not power up. The fans in the PWR supply do not run either. I checked the internal fuse in the power supply and it is good. There is no smell of magic smoke from the TV or power supply and no components appear burned inside PWR sup either. I suspect the power supply is faulty. Any ideas appreciated.

Power supply failure- I found the filter caps were all cooked dry and the yellow glue they use in this power supply turns conductive where it turns dark brown. Unsolder the devices and feet on the heatsinks and remove them along with the stand-up driver board. Change all caps-1000u/16V, 470u/16V, 47u/50V, 10u/50V. Scrape and pick off the brown glue from all devices. Re-assemble. Mine would then fire briefly and I noticed only one fan was turning. Removed the fan and found the bearing was seized in it. Power supply will now run properly with the defect fan unplugged. I won't service one of these again-the picture sucks!

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.
Open up the back of the set and follow the power cord feeding the TV, it should be connected to the circuit board which will be the power supply module. Look at the power supply first; look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find.
Same thing here. Seems like there is an issue with the power supply. There is an interesting buzzing sound coming from the power supply. The power supply is located underneath the rear panel of the set. The panel is relatively easy to remove and it looks like the Power Supply would be pretty simple to replace.
Would like to know where to get a new one. This TV is just over a year old and out of the manufacturers warranty period.
If anyone else has tinkered around with this set and has any other incite to share Id be very interested in hearing it.
Mine did the same thing and it was the back light board. Good luck getting one. I had to threaten to sue them and badger Audiovox until they mysteriously had one. Now my power suppy is bad at least I got another year out of it. This TV SUX!
