Question about Audiovox FPE3000 30 in. HD-Ready LCD Television
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. j
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!

All I do is turn on the unit so the red light goes of then I bang the power supply until the fan comes on. The screen comes up shortly after.

I would suggest getting a schematic of the set and using a multimeter looking at the power supply test points to determine what is happening exactly with the power supply.

Thanks,
I will attempt to find a schematic. I have been looking for a couple of days and have been unsuccessful. Guess if I can't find one I can just reverse engineer it.

I am having the same problem with my FPE3000. Did you have any luck repairing it?

I have a similar problem with our 3000. The unit was turned off one evening and will not come back on the next morning. The Green light on the power supply is lit, but neither of the fans in the supply run and the TV will not come on. I have had no luck in finding a replacement power supply from any net search or the company direct, any suggestions?
I have exactly the same problem with FPE3000 .I am trying to find another power adapter but is impossible.
Hello all,
I have been unsuccessful in getting a schematic for the unit. I did open the power supply (brick) and found nothing burnt. No evidence of overheating although these are the symptoms. I have found in my case that when the unit will not turn on I unplug the unit from the wall and after a couple of hours when I plug it in it works. This confirms that the problem is in the ps and not in the television itself. Sometimes this works for a few days but the most recent time it has lasted weeks without shutting down. I have been looking for a replacement for the ps but have been skunked on that. I suspect the internal ps parts are used in other power supplies but do not have schematics or any other demo units to compare parts to. If anyone can score a schematic please post and I will take readings/troubleshoot. In the meantime my solution is working for me.
I always suspected the Power Supply (PS) would fail on this TV. The fans often make funny noises.
Now the thing seems to have failed but not completely, I see the Audiovox logo and then blank.
Has anyone tried a new PS? Did it work?
We can help you costomer make the special power supply if you can send us the old power adapter.

I Repaired Power Supply (PS) on this TV.
Now every time when turn on the TV, I see the Audiovox logo for half a second and then black screen(back light goes off)and minute later green indicator light blinks.
is it the power supply which is shorted or the pwr supply regulator
