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

3 Answers

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. j

    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?

    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?

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.

    I have found by just calling the company and asking for the service documentation and the engineering diagrams they will send the for a fee, but you will have factory approved docs to go from.

Sound but no picture


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.

Good Luck!

Is there a fuse and where on 32 audiovox, no power


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.

Audiovox model FPE3000, has sound and picture but


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.

Audiovox LCD FPE3206 problems


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.

Thanks
