vizio e470vle power supply debacle

[SToomey006]

Idk what happened I typed paragraphs and they all disappeared so give it another try... long story short i need a new power supply for my e470vle. I was troubleshooting the board and like the amateur I am hen it comes to the inner workings of components, After diagnosing the fact that there were zero volts coming off any of the pins at CN201 (where the harness plugs the wires into the supply that goes to the main board. at every single port I had zero volts. Then i checked every fuse, believe there re 12 on the pwr sup alone, and then the voltage coming in at the plug adapter, which ws a solid 120v. So i tested every diode, fise and resistor and they all read correctly. Then I made a foolosh mood and pressed down on the board and the bottom ht the chssis, and my drivers side space suffers the moet w stuff like that. But anyway, I fried a part of the board so im just going to check it, howver i was hoping that there's something else i can like we can hook the lights up and go from thrt
So yea if you have any questions o comments PLESE help me out here. SOOO excited about this tv i just want it to work :-/ have a good night ghentlemen and thanyou for your time

Re: vizio e470vle power supply debacle

Sean,
The E470VLE model uses 3 different types of Power supply boards to my knowledge, could be more.
Please be very specific and give us the part number of the board. The part number for your board should be located on a barcode sticker and start with the numbers
0050-04XXX-XXXX

Re: vizio e470vle power supply debacle

the board part number is: 050004071210
and thankyou appreciate the help

Re: vizio e470vle power supply debacle

woh i just reread my post from last night aaaand it looks like an autocorrect nightmare. Sorry bout that. Not sure i can edit it, dont see an option to do so. I was half asleep and frustrated I had lost the original message i was typing. to clarify, I had the board plugged in to check voltage, but had unscrewed it from the chasis, then went to unplug it and accidentally grounded one of the hot contacts on the bottom of the board by touching the chasis. Thankfully the board wasn't connected to the main board or anything else at that moment so that was lucky but man, in hind site it was very careless. Wow Just read more of that, i can't even understand what I wrote. I wish i could say I was drunk or something but can't even say that lol. So I'm not sure how you deductively reasoned out what I was asking, or maybe you just happened to address my main question that I didn't communicate AT ALL. Which was whether or not other power supplies are compatible. Cuz the exact one I had is def more expensive than many I've seen, and it failed anyway, so would it be prudent to go with a more reliable one? And on top of that I've seen a bunch of online sellers that say for example, we're out of stock on that, but these 4 or 5 other options are "compatible" with that one.... Sounds good on paper and some are less expensive, but I just want to be sure before I get ahead of myself again and pull the trigger on the wrong part. Again apologies for that first post, Idk what the hell happened there lol

Re: vizio e470vle power supply debacle

Is this the board? Vizio 0500-0407-1210 (DELTA DPS-270DP)
http://www.shopjimmy.com/vizio-0500-...upply-unit.htm
So what DCV do you have between the two legs of the main filter cap in the primary side of the circuit?

Re: vizio e470vle power supply debacle

Yes ideed that is the exact board that I have. I'm wondering if other "compatible" boards are in fact compatible and if so then wouldnt it make sense to go with one that's more reliable? My board is sold out in a number of locations ive looked, which leads me to believe its probably a popular replacement part...yea? Anyway I'm not sure the DCV at that location you asked about on the primary side. I'm unfamiliar with what that is but more importantly, well i'm not sure to be honest at this point it seems foolish to try any further diagnostics since I roasted CY1 while trying to unhook the power cable without the board screwed to the chasis. Couldn't feel any more foolish and was devastated when I did that. Hours of research and testing components straight down the drain. (Its all down the drain as far as I understand anyway) and for some reason the area that really got the brunt of the roastage was all the way across on this resistor which seemingly is miles from whatever CY1 is (I didnt get that far in my studies the other night) But yea R820 like REALY cooked something fierce comparatively, and singed the board along its path towards L801? Under the bridge behind the bridge rectifier, a fairly decent sized something or other next to a copper coil.... (sorry for my lack of vocabulary) My electronics experience is primarilly to and from components and installation. This is my first real adventure inside a faulty component, let alone a circuit board inside said component. I'm getting there knowledge wise and understanding but the problem I'm faced with was my carelessness shorting out the board and cooking possibly those two spots simultaneously or one leading to the other somehow. The gold fillament that connects that resistor (820) to good old unknown L801. Is there even a way to fix the connection, or is it even worth while to attemt? lord knows what got cooked when i did that but thnkfully i didn't have the main board or the other two (i assume) illumination harnesses that normally would be plugged into the board.
So anyway long story short I'm all about trying to fix this board but I have a feeling my careless mistake made it nothing more than an expensive paperweight/parts board :-/ And if thats the case is there a better more reliable board that will serve the same purpose. or if for no other reason some of the other boards are less ecpensive as well

Re: vizio e470vle power supply debacle

Does anyone know if you HAVE to replace the power supply with the same exact model as was in your particular tv? Or are there other compatible power supplies that will perform the same function if not better? Given the fact my supply failed, I'd like to hope there's a better option. Plus all it does is supply x amount of current to the main board and to i believe illumination or the backlight whichever or both lol. Thoughts?

Re: vizio e470vle power supply debacle

It has to have the same pin out for the connectors, same Voltage rating, same or higher current rating.
Per shopjimmy, it does not show any sub for this power supply.

Re: vizio e470vle power supply debacle

AHA! Ok i see. I got mixed up on shopjimmy, I had searched via tv model number instead of the part number n the board and had seen a bunch of compatible parts etc. ONE of which I think might have worked... the 1290 (last 4) but theres no sense in chancing it or screwing around over 10 or 20 bucks. Thank you both for all your help. And Nick's Tvs, now I know what you meant by the e470vle using 3 different boards. I wasn't sure if you meant it was capable of using any of the three, or that dep on which e470vle it is it could have and need only one of the 3. Now that I reread it w you asking for the model number etc it's glaringly obvious lol. Thanks again guys I'll post again when I put the new one in.

Fairly comfortable w the procedure but that being said I dont want to overlook anything like last time. Any common errors or areas of concern in terms or installation of the new power supply? Do i need to put the tv back together again b4 i try it or can i just mount the board on the chassis and plug it into the main board and the other 2 wires and hookup an ac cord and go from there? Oh I dont have the original power cord but my lg has the exact same 3 prong female plug that you plug into this one. I know this sounds stupid but just to verify, THAT doen't matter bc 120v is 120v end of story. And there's nothing on the cord like an xbox power supply for example or a computer cord w the little box. It's just wall socket to back of tv just like the vizio version of the same.
