Question about Audiovox fpe 3207 32 in. LCD Television

Open Question

Audiovox FPE3207 LCD TV. Normally the word 'AUDIOVOX' appears, goes off, and, after a brief time, the TV comes on. Now 'AUDIOVOX' flashes, and after a while, the sound and a faint station image pops on and off as the screen tries to light, This cycle repeats, If I turn the set on and off a number of times, eventually the screen lights fully and the set operates normally. I suspect the inverter but can not find a replacement.

SOURCE: Audiovox FPE3206 - Power Light is Blue/ON but Screen is BLACK

I had the same problem, except with a flashlight I could see AUDIOVOX when i turned it on and I could see the video when I put a DVD in. It is hard to see even with a flashlight so you have to look closely. Well, I researched and investigated what might be the problem because I was upset that I had the TV for less than two years. Everyone was saying the inverter was defective. Apparently the inverter is what gives the LCD screen the back light to see the video. So I called audiovox and found that thier part's selection was only a power board and a remote control for this TV. I asked them if they could get me an inverter and they did. With shipping cost it was approximately $150.00. They ensured that I know that there is no refund on this part (which is common for electical parts). So I took a chance on it not being the right part for the problem. I replaced the defective inverter myself and it worked. It solved my problem. The inverter is a circuit board that plugs in and has a few screws to hold it in place. I had to remove the back cover first and a couple of brackets inside the tv to get to the inverter and replace it. There is a quite a few screws so I recommend writing down where each came from for easier reassembly. I hope this helps!

SOURCE: Audiovox LCD FPE3206 problems

Hi, All.
I ordered a new power supply module on ebay. Cost about 106.00 delivered. Came in a few days. I replaced the unit, bunch of screws, all wires were cable plugins, no problems at all.
After reassembly, it worked. What can I say? Sometimes ya just get lucky.

You need to verify first that you do have 24vdc feeding the inverter boards, if you do have 24vdc then we can be sure it is the inverter boards. The inverter board will have very small surface mounted fuses, check for that also.

SOURCE: the tv will not come on. it started to have trouble coming on, and them it quit all together. while it was starting to act up, when it would not come on it would reset the clock on this audiovox KLV3

This sounds like a very common issue.

If set is hard to turn on (takes several tries)but will eventually turn on here is what my guess would be.

Every set has a standby power supply that is running 7/24 if the set is plugged in and it supplies voltage to the remote circuit that turn on the main power supply for the tv and hence turn the set on.

This is an area where companies cut corners by using lower rated voltage caps. By this I mean Standby usually provides under 10 volts to trigger the set on----what they do is use filter caps rated at say 10 volts max in a circuit with 9 volts (example)=with the standby on all the time the filter caps (electrolytic caps) dry out and fail.

The problem usually begins where you have to turn set on or or two times and gradually gets worse--takes longer and more tries to get it to come up.

Once on it will stay on until turned off for a period of time.

The caps will begin to work better (regain some of the capacitance) as they get hot--hence one it is on it will seem ok.

The beauty of this problem is most of them happen when set is a year or two old (no warranty) and all you have to do is look at the top to locate bad ones.

They are generally black or blue and round and vary in --they have two connections each--a + for positive and a - for negative--not unlike a battery which in a way they are. The + and - are marked on top and bottom of most boards.

They are easy to replace and not expensive parts.

The tops are silver and metal looking with creases on top and if bad they will be puffed up on top---tops must be perfectly flat with no brown material leaking top or bottom.

If this is your problem once you id them (make a drawing) you can begin.

Here is the critical part---on each cap is also marked the value like 220uf 10 vdc---220 micro farad at 10 volts maximum.

If you find for example 6 puffed up and all are 10 vdc replace them with the same value capacitance (like the 220 uf) but go up to at least in this case (from 10 volts) to a 16 or higher rated voltage cap.

The only issue is when you go up in voltage rated value the cap is larger so sometimes there is an issue of physical space for the replacement on the board to fit them in.

The reason they cheapen these sets in this way is if 10 caps and you make 25,000 sets there is a considerable savings in parts cost.

They do not care as long as it lasts past the usual one year parts warranty.

I have taken the time to be long winded because this really sounds like it may be the problem you have.

See attached photo of a typical cap and if you have questions or need advice let me know. 8_30_2012_2_40_15_pm.jpg

Tv power comes on but no picture th name Audiovox


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.

Extremely long warm up time 25 minutes. ok once it comes on.


Just a shot in the dark- I think your main projection lamp is going bad- If the set is more than a year or 2 old it can happen. Unfortunately they are a little expensive.
How is the brightness level after it warms up??
