Thanks for that link JJ89. I hadn't seen that one and it's a good explanation and thanks for contributing to the thread.

I saw a post (#2507) in the Vizio 601i-A3 Owners thread where Larry had a working 601 in the affected WAN range, did not want to wait for it to fail, and requested a new replacement. Vizio Customer Service replace it with a new WAP set. Apparently Sharp or the chip manufacturer is picking up the the tab for the in-home replacements. After reading Larry post, I ordered my WAP replacement last week and have received a tracking notice. I much would to have an hour of downtime that a couple of weeks if my WAN set fails. Props to Vizio for the way they are handling the problem.

Not having a warranty I don't know if I qualify for that, I guess I should contact Vizio support and find out.

Anybody know what the difference is between the E601i-a3 and the E601i-a4? Please don't say "1A". Just wondered if this is an updated version.

UPDATE: TV is still operating great as of this date and Vizio has just done a software update to ver 2.0.21. I noticed that with this update that the TV boots up faster.

I wanted to ask, being as I didn't exactly do my homework before relocating overseas, is there a way to swap out the power supply for one that likes 240v and 50hz? I have the e701-a3 and love it (I hope to continue to).
post #37 of 68
240 VAC to 120 VAC is easily accomplished using a 2:1 Step Down Transformer. The 50 Hz should not be a problem, but international broadcasting standards and frequencies can be a challenge. For example, PAL is used in Europe. Most of the players supported both NTSC and PAL.

"240 VAC to 120 VAC is easily accomplished using a 2:1 Step Down Transformer."

That part was the only part I researched. The 50hz A/C I didn't. I'm guessing that as the hz is lower here than in the states, the tv would not get as much electricity as it did. As far as the refresh rates, I figured the set top boxes available here would be able to adjust from the 50hz to 60 for over the air broadcasts. I also have the tv hooked into a tower, so we watch our movies and stream through that instead of using the built in apps. Unfortunately, I made the assumption that a step down voltage converter would fix the 110v need and then I found out that there may be an issue with the hertz as the step down converters don't adjust the hertz rate of the a/c current.

Thanks for your help.

The 50 Hz is an electrical frequency and most power supplies will easily filter 50 or 60 Hz. However an electric clock will use the line frequency and 60 Hz clocks and AC motors will run slower with 50 Hz electricity. For devices that are "dual voltage", for example, electric razors, PCs, Laptops, and other electronic equipment, the physical plug or electric cord, can present a challenge because the electrical receptacles can differ from country to country. Here is a Web site that might be helpful for identifying the proper plugs or adapter plugs, AC voltages, and AC frequencies, http://kropla.com/electric2.htm. Radio Shake has a lot of international power adapters.

I forgot to mention DVD Region Codes. The players and media have to be compatible. Living abroad can be wonderful, but there are challenges.

Has anyone had a problem turning off the E601i with the remote or set's power switch? Power cycling fixed the problem, but the question is wonder what caused it? Just askin'.
post #41 of 68
We've got the majority of our appliances sorted out. The only two hang ups were on our surround sound stereo and the e701i-a3. Power requirements for both are 110v @ 60hz. The rest of our gear, fortunately the majority of our things have switching adapters, so all we need is the adapter to get it into the socket and the rest is handled by the device. We were not so lucky with the tv and surround sound system.

Well it's been 6 months and the board warranty has run out and the set is still running great so I guess all is well in TV land.

Hey there, first time poster here..

 

i bought my refurbished e601i-a3 and it lasted for about two months before i got the horizontal lines down my screen. after doing some research and finding this thread i got a new ZG tcon board and replaced the old ZG board that came with the tv. unfortunately, i still have the same exact lines going down my scree! can you help me troubleshoot with what else might be wrong? i hope it wasn't the static electricity, i was pretty cautious about it, i wore gloves and tried not to rub my feet on the carpet lol. maybe it's not the video card? if not, what else could it be? isn't the t-con board solely responsible for the infamous vertical lines?

 

i'm pulling my hair out trying to get this tv to work again! 

post #44 of 68

possibly bad ribbon cables to the t-con board?

post #45 of 68
Thread Starter 
A bad ribbon cable is the last thing that I would suspect (unless you can see some obvious cuts or frays). There are only three boards in the set (not including the panel) if you changed out the T-con board and you still have the problem then you could have bought a bad board. The main board works with the T-con board to supply data to the panel in time, by this I mean that the set is a computer and all data is transferred between those two boards in time or I should say in sync and depends on a clock timing thing. That's why it takes so long for the TV to boot up, the two boards need to be in sync and it's waiting for the clocks on each board to lock together. The sync'd data is then passed to the panel which distributes the data to the many receptors to make a picture. The fact that you say it worked fine for two months leads me to believe that the problem is either with the timing controller (T-con) board or the main board although the panel could be at fault but that's least likely IMO. If you bought the t-con board from an online dealer and it came with a warranty, see if they will replace it as defective. If you took the back off the TV make sure that you put all the screws back in the proper place and put back any ground wires that you might have taken off. Sorry but that's the best advice that I can give from my armchair.

If all these pictures aren't large enough for you, you can download them all at my website in full hi-res here http://www.eaa1358.com/Vizio/

Vizio tech support was helpful in that they gave me three URL's on the web to obtain replacement boards and they said that they partner with these sites and here they are;

VizParts - (888) 260-7765 www.vizparts.com.
Encompass Parts - (800) 432-8542 www.encompassparts.com.
Shopjimmy 877-881-6492 www.Shopjimmy.com

Well that's it and I hope that this information was helpful to you.


I know you mentioned you originally didn't have picture but there was sound.  Which board would you suggest me replacing for neither picture nor sound?  When I turn the TV on, it blinks like a strobe with no images.  Just a black screen blinking.  I can turn it on by remote or manually but that's it.

It's hard to say that you didn't have sound because with no picture you wouldn't know where you were channel wise and know that you should have sound at that point. This happened to me, the only reason that I knew that I had sound was because the picture went out while watching a program and the sound was still there! When I tried to change channels I lost the sound and didn't know where I was anymore. In answer to your question, on the E601i-a3 I would change out the T-Con board first.
post #48 of 68

Hello, and thanks for this very descriptive explanation.  It is the most comprehensive I've found online so far.

I have the E701i-a3, (which we all agree is similar enough in design).  

My tv has a small segment of LED backlight on the lower portion of the screen about 10 inches long that is dark.  I've so far learned that the LEDs are likely wired like Christmas lights, where if one small bulb is faulty the whole section will be dark.

I intend to remove the segment of LED and either solder in a new LED if I can find the bad one, or else replace that LED module.

My question for you is how to specifically get these LED modules out, and if necessary, can these be bought individually.

Please help.

Thanks

I haven't had this problem before so I can't help you specifically, but if the panel comes apart and you can get to the affected led string, then I would turn the tv on and use a VM (one lead to ground and the other on the string) starting at one end and proceeding through the string checking for voltage until you find the dead spot, that should get you to the bad led. But it could also be the power supply board which I think has more than one voltage feed to the led backlighting (I think it has two) check to see that both outputs are feeding voltage first. It's just a suggestion!

Here's a list of board #s for the E701i-a3:
Power Board = Vizio 09-70CAR000-00 Power Supply / LED Board
Main Board = Vizio 01-60CAP001-00 Main Board ( This board is the same for the E601i-a3)
T-Con Board = Sharp RUNTK5261TPZH T-Con Board

I purchased the Vizio E601i-a3 a little over a year ago and have had no problems till the other day. My issue is there is a bright white light in the top left corner. The picture looks horrible. There is no difference between SD and HD. The picture is grainy and real bright. I can adjust it to be darker but the picture is just bad. Was just curious if anyone has had this issue. Would like some input on what parts I might try or if I'm just doomed! Thanks
post #51 of 68
Have you tried talking to Visio support about a warranty repair? The additional one year warranty on the E601i-A3 might extend to your problem.

Well as of this post date the TV is still working great. I have added to my TV by purchasing the VHT-215 soundbar and the XCV100 Skype camera, both are working great! I read a post somewhere that said that the Skype camera didn't work with the E series TV's but with the latest software load of 2.0.21 that Vizio installed and now having access to the Skype app I decided to buy the camera and try it out. I made a Skype video call to my son in Seattle from here in Alabama and it worked just fine for me.

Sorry "Firedog" about being so late to answer you (somehow I missed your post). I ordered my parts from "shopjimmy.com" but there are others such as; "tristatemodule.com" "rivervalleyelectronics.net" and "discount-merchant.com" Just look to see who's giving the best deal today.
post #57 of 68
Flyguy, thanks for all the info. I changed my tcon board on my e601 but after powering up again it now shows no picture (prior it had a thin vertical green line over all images). When I plug the tv into the electrical outlet I hear a random "popping" sound from the speakers for the first 30 seconds. It seems there is some power being supplied at least initially since the speakers are popping but not sure what the issue is now. Power button on the tv and the remote are not turning the tv on. Anyone have ideas on my issue here? Thanks for any info!

The TV being locked up and wont respond to the remote or the TV on-off switch is usually caused by not being patient when entering commands with the remote. Unplug the TV and then re-plug it back in and that will usually restore the on-off switch and the remote capability. Be patient with the input of the remote and give the TV time to respond. Check all voltages on the power board and make sure that the edge lit LED's are turning on. If all that checks out then I would replace the mainboard.

Fly guy, I checked the power supplied to the power supply board and Ian not getting the correct power supplied from the power supply board to the main board. The labels next to the wire harness lists post 1 at 3.3 volts and I get 6.4; posts 4, 8 and 9 at 12V I get 26.3V and the tcon post #14 at 12V and I get no reading at all on that one. I assume this means the power supply board is bad?

Here's a URL for the power board if you care to replace the one that you have now. http://www.shopjimmy.com/vizio-09-60cap000-00-power-supply-led-board.htm
