Question about Televison & Video

Open Question

Purchased a VIZIO VO400E HDTV on 1/14/2010. Before I even unpacked it, I noticed fumes like circuit board or plastic coming from the package. The fumes come from the ventilation grill at the top of the set, get stronger when the set is on but persist even when the set has been off overnight. The fumes seem to have diminished slightly in the last few weeks. Though the set performs well and gives an excellent picture, I'm thinking of returning the set and buying a different brand just to be rid of the fumes. Friends who have purchased other brands of HDTV do not seem to have this problem of fumes coming from their HDTVs. Anyone have else have this problem with a VIZIO HDTV?

Well, I can tell you it shouldnt have anything to do with your not having an HD box. The TV does not require a HD signal to give you a quality picture. The HD box only gives you the enhanced HD signal, but should work as any regular TV without it. How do you have it connected?

SOURCE: Weak Coffee

Yep, it's the one inherent flaw in the single serve machines - someone else decides what 'the perfect cup of coffee' tastes like.  Quite presumptuous, actually.  
Solution I found to be acceptable:  Buy only the extra bold flavors (there's about 5 or 6 varieties) and brew using the small cup size button.  Yes, you only fill your mug about 3/4 of the way, but at least you get a decent cup of coffee.  
The ONLY flavor I found to be strong enough when brewing with the large cup control button is DOUBLE BLACK DIAMOND...the rest is crap.

SOURCE: Vizio 47" Costco hdtv has red floating areas!

After posting this problem we did call Vizio. They sent out a repairman (had to wait over a week) who fixed it by: Replacing the LVDS cable and the main board. (Just like somebody on this blog wrote somewhere!) We also had just previously called our cable company who came out (also free) and checked our system only to find the cable running around the house to the tv needed replacing as it was sending zillions of errors. The red flowing problem (called "red pixilation") was due to the Vizio LVDS cable and main board being faulty from the factory.
Just want you out there in web land to know how to get your similar problem fixed!

I want to know how a 50 inch vizio tv purchased in 2015 could be broken and the vizio people tell me to throw it away. surely someone can help me replace this inferior product.


Hi Pat.
There is a white sticker on the main board/motherboard that has numbers on it. The replacement board numbers or partial numbers,(except last 4 I believe) has to match, if not the TV may not operate correctly, or may not operate at all. Let me know.
Hope this helps.

Hi, Typical I leave the my bedroom tv on upstairs it's a Vizio 32' HDtv well typical after a few hrs it well have a notice on screen that there has been no changing of the channel it


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hi my tv fell off the wall last night about three feet to the carpet now it won't turn on the amber vizio light won't even come on when I plug it in. I took it apart and nothing appears to be...


After a fall like this (even on carpet) it probably has a cracked circuit board or a loose connector, first (since you took it apart any way) look for all connectors, than unplug them and re-plug them to make sure all plugs and boards are seated correctly, if you still don't have luck, than take out all the circuit boards and check them for cracks under a good lamp and magnifying lens, than repair the cracked traces with a good soldering gun by scratching off the varnish coating and applying solder. (if the crack is to wide you can solder a peace of coper wire to the trace on the board)

Have fun!

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

check out the power supply board! Look for popped capacitors. They either leak or swell up. They are the can shaped things on the board with the plastic coverings on them...you can usually see a swollen cap sticking up over its covering as a telltale sign.

Good luck and be careful

Have a new 40'' Vizio VO400E LCD HDTV and randomly the brightness pulses for no reason when I'm watching TV. We have it hooked up to a Directv dvr.


check to see if your TV has an ambient light sensor that automatically changes the brightness of the TV based on the lighting conditions. Sometimes the sceen on the TV can impact the sensor and dim the TV for bright scenes. You should be able to disable this feature if you like.
