Re: Vizio E70u-D3

Thanx Andrew..

Now that I have gone thru the mourning period, things aren't TOTALLY shot..

As you can see by the pic, the main area of the TV is still there and is viable..

I am wondering if the small strips of scrambled-ness (marked in red on the pic) are the results of misaligned bond connectors rather than caused by the actual break (marked in green)...

Is it possible the small crack would affect the opposite side of the panel??

If I can fix those two scrambled areas marked in red, I would still have a viable TV that I can use at home... Instead of a 70", it would be a 67"

I am so frakin' depressed!!

Re: Vizio E70u-D3

Yea, I think yer right.. I think it best to keep the panel where it is and gently move the assembled onto the screen...

Helper couldn't get over here yesterday so we're shooting for today..

Re: Vizio E70u-D3

Think I would choose the first one, seems like it's the procedure with less stress on the panel.

Or whichever puts less stress on panel.

Ahhhh...I see you have a lovely little helper there...a young budding engineer perhaps...

Re: Vizio E70u-D3

Can we see the pictures of the old LED with the LENS removed?

Do you need them powered???

Went ahead and did both powered and unpowered..

Although the pics make the LEDs look purple, they are a definitive blue...

Re: Vizio E70u-D3

Taaa daaaaa!!!!

And no cracks in the display panel.. so far.

I have to admit, I was skeptical of the idea that I could have an entire set of LED strips the wrong color...

What could have possible caused that?? Is there a market for a set purple/blacklight LED strips??

Anywhoo, we're cooking with gas now..

One last dilemma..

When I broke down the TV to the bare panel (I am a one man operation) I laid the TV on a flat surface and then proceeded to remove all the screws and fasteners that held the metal back of the TV to the panel and diffusing sheets... I then lifted the metal back off. Not an easy task, considering I have two bum shoulders..

My original plan was to simply reverse the process.. Unfortunately, that plan did not survive contact with reality.. When I took the metal back off, the plastic frame that holds the diffuser sheets in place and forms the support frame for the display panel came off in pieces.. Not broken, but designed sections..

So, being nimble on my feet, I took the diffuser sheets off the display panel and placed them onto the metal back of the TV (LEDs facing up)... I then proceeded to re-affix the panel support frame on top of the diffuser sheets and secured to the metal frame back...

So, now I am left with this... The assembled metal back and the display panel facing downward...

I am THINKING that my best bet would be to flip the metal back of the TV and, with the LEDs and diffuser sheets facing downward, place the assembled unit onto the display panel very VERY gently.. I can probably get my daughter to come out and help me lift it and place it..

The only other alternative is to take the display panel, flip it front side up and then place it gently onto the assembled back part of the TV... At first I was thinking that's the worst possible way to go. But, as I typed it out and visualized it, it didn't seem to be as bad.. Especially if I have a helper to help me maintain the integrity of the panel without any major bends...

What's ya'all's thinking???

That last pic is just because my granddaughter is so gosh darned cute..

Re: Vizio E70u-D3

OK I ordered another set of LED strips.. Seller was kind enough to throw in the LED power PCB connector...

Hopefully, the LED strips was the issue....

I'll update the thread when they arrive...

Thanx to all for all the help..

[Michale32086]

Re: Vizio E70u-D3

OK I figured out the issue with the LED strips that don't come on.. Turns out when I was using my LED tester before cracking the unit open, I enlarged the connectors so they are not making a good connection..

Crimping them back into shape solved the not coming on problem..

Re: Vizio E70u-D3

Change out the LED strips for the COOL WHITE type. This will fix your problem. You could probably use the PURPLE LED strips as decorative lights.

Yea, it's weird that this entire set would have the wrong LEDs...

Closeups of the connectors that don't light up full strip and half strip..

Re: Vizio E70u-D3

OK Update on this...

I am just going to throw a bunch of data out there in hopes that it makes sense to someone..

First off I got it disassembled down to the bare LEDs.. I am fairly sure I didn't crack the panel.. hope hope...

Once off, the LEDs throw off a distinctive blue-ish glow, rather than a purple.. But it's close enough that i can see how it could look purple under all the mylar sheets and diffusers and panel...

However, some of the LEDs are distinctly white, while the majority are definitely distinctly blue-ish.. The pictures don't show it properly, but the LEDs are distinctly blue-ish, not purple... And a handful are distinctly white..


As you can see by the pictures, one full strip is off and another half strip is off.. but I DID swap those strips out for others that are fully working so I know the strips are good.. It must be in the Power PCB or PCB to Strip connector...

That's what I got so far..

The "fix" according to that is to replace all the LED strips..
