Audiovox KLV3913 TV/DVD dead

Audiovox KLV3913 is not working. Most of the time, it will turn off after a couple of seconds after I turn it on. All the LEDs flash on and then it shuts off. Occasionally, I can get it to stay on. When it stays on, the radio works but DVD and TV do not. At one point I could hear the TV audio but not see it. I have not been able to get it back to that state though.. What I tried: Unplugged from the wall and plugged it back in. Let radio play for about 10 minutes to see if it just needed to "warm up." Also... There is a slight high-pitched whining sound coming from the unit when it is OFF but plugged in. Please help. Thanks, Andrew

SOURCE: no picture.

Tell a tech you need to resolder the legs on the inverter board - this should cost you a LOT less than letting them poke around to find the problem. This is a common issue with the Darfon v144-001 boards used in the FPE3000.

SOURCE: Power Problem

Sound no picture and red dot/sparkles/speckles fix summary

This post is basically for anyone that stumbles across it trying to fix what seems like two fairly common problems with plasma tvs. I apologize for the length of it but hope it can help others.

To start off, I got a free Audiovox FPE4216P 42" Plasma TV.

The previous owner said that there was a red cloud in the top center that after time spread across the top and down the center of the screen. Some time later, they were watching it and it was as if someone simply turned the power off. After that, there was no longer any picture - menu or otherwise.

After much research on the net, it seems that fixing plasma TVs is strongly based on the educational guess method. This compounded by the fact that replacement parts are quite scarce and generally crappy customer service provided by the manufacturer if the TV is older than 14 months basically makes many of these TVs $2000 doorstops if something goes wrong with them. Luckily, my TV uses many LG boards which seem to be used in a number of different makes and models.

NO DISPLAY ISSUE:

Once I took the set apart, I first checked the power coming into it and it checked out ok. I then found a fuse on the YSUS board that had blown, upon replacing it, I no longer had sound. The indicator light on the front would turn from red to blue for about 3 min then back to red. After this happened, the LED on the power board would light up and the there was no longer any response from the power button (led on front would only stay red). I would have to unplug the set and plug it back in to duplicate the above.

I then checked the voltages for Vs, Va and 5v on the connectors coming off the power board (using the DC setting on a voltmeter) against the specs on the sticker on the back of the display panel and they checked out.

It was recommended that I change the YSUS board since the fuse had blown on that board. This seemed counter-intuitive to me since it seemed that the power was fed into the YSUS board through that fuse first as if to protect the YSUS board.

With reluctance, I purchased a "new" YSUS board. Once I popped it in - presto! I had picture! But picture with a cloudy, sparkly red "I" beam that would show through the dark areas of images including the menu screens. It seemed that as long as there was a color over where the "I" beam ran, it was fine and there was only a problem when the image was supposed to be black.

RED DOTS - SPARKLES - SPECKLES - and possibly MAL DISCHARGE ISSUE:
I say possibly mal discharge because it seems that some label this problem as such where some describe mal discharge as another problem.

After much research on the net (again), it seems that there are two fixes for this problem: 1 - a new control board and 2 - adjusting the voltages. It seems that each fix has about a 30 - 50% success rate. With the first fix, you just pop in a new board and you could be done or you could have the same problem. With the second fix, people have said that the dots have gone but the image is now crappy or they have different color dots. Some also say that merely changing voltages will only temporarily fix it. I opted for the cheaper second fix.

My power board has two potentiometers (pots) on it (adjustable dial thingies). One for the Vs and one for the Va. I first made sure that these were adjusted to spec. I took readings off of the molex connector and grounded to the support bracket of the set.
My YSUS board has 4 pots, two are labeled SetUp and SetDn and the other two are on little circuit boards rising off the YSUS board - one of which was completely inaccessible due to it's position behind the support bracket.

I first set the TV to an empty input since the red showed best against all black. Jacking up the SetUp pot seemed to have the effect of making the black really black and essentially removing the red. SetDn didn't seem to due much and I didn't mess with the other pots. When I switched to an active source everything looked great but then I started to notice that on bright images that weren't quite white, there was blotchy pixelation and redness. It then started messing with all three accessible pots and got the image to be really good but I could still see some red and now blue sparkles in the dark areas.

I was pretty satisfied with my results but there was that one other pot that I could not get to unless I removed the YSUS board. Since I knew I would have to adjust that pot multiple times, I decided to remove the board and drill a small hole in the support bracket to gain access to the pot with the board installed. For me, this was the most difficult and frightening part. I didn't want to damage the panel itself and I also didn't want to get metal shavings everywhere. I carefully masked off the area and nearby boards with paper and when I drilled I held a piece of wood behind the bracket.

I then had access to all 4 pots and just kept messing with different balances between them. I used an empty input to check the black and numerous DVD's to look for crappy picture on lighter areas. As it turns out, the menu for the Underdog DVD really showed the light image flaws.

Now, the image is about 98% perfect. When a lighter image turns to complete black, there are some, extremely diffuse red and blue brief pixel flashes (just for a millisecond) but then the black stays black. To notice it, you have to be within 3 or 4 feet of the TV which I think is too close anyway for a 42" TV and is virtually non-existent when watching DVDs.

Here is some extra part number info with possible equivalents:

YSUS: 6871QYH953A or 6870qyh005B and possibly 6871QYH053B EAX31974801 EBR31872801 EBR32642701 6870QYH105B EAX31631001 EBR32642702 1032298-hs

Control Board: 6871qch977b or 6870qch0C6b and possibly 6870qch006b 6871QCH077B 5070-5623

Power Supply Board: 667-PH42FB6-20 or 782-PH42D8-200a and possibly 6FB0192010

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.

SOURCE: 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??

SOURCE: no picture only sound

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty with some type of extended purchase plan, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Why is the picture is very dark? We can here sound but can't see the screen to fix it


Back-light fault. Low intensity. Contact any service technician to locate the faulty component, and get it repaired.
Check and replace damaged component/s at its backlight inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do a search by type in the brand name of your device at its search box. It will be best to replace the inverter board as card basis.

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 KLV3913,...


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

We have a Audiovox KLV3913 under cabinet tv/dvd combo that has a DVD stuck in it. Push the open/close button & "Open" shows on screen but door never comes open. No longer have manual & couldn't...


There has to be a small hole at the front of the door where u will be able to insert a paper clip and press then dvd shud eject. If not open door with a paper clip and manualy pull the drawer outwards, though be careful and do it slowly thus not damaging the gears of the ejection system. hope it helps. regards.viv

Won't charge


Does anyone know the warranty on this product? We should file a class action suit because obviously we are all having the same problem with the charger and they must know about it. Mine is only a couple months old and used sparingly - now its dead. I called Audiovox at 800-645-4994 and went thru automated hell to speak with someone. They referred me to www.18002526123.com which sells parts (chargers) for the DVD player. That is totally bogus - they sell a bad product then want me to flip the bill to get it repaired. I don't think so.
