VIZIO 60" E60-C3 Bad Single LED In Each Strip

[Michale32086]

One of the more exciting aspects of TV repair, at least for me, is repairing bad LED strips.. Mostly in LGs..

Having to pull a display panel off of a 60" LED adds a whole new degree of difficulty..

The symptom is an LED TV that blinks on, then off very quickly... Once I eliminate a power PCB issue, it's invariably an LED strip problem..

But usually it's a single strip that is bad. In some instances, 2 or more... Replace them and everything is copacetic...

But this Vizio has something I have never seen before..

This Vizio has a bad single LED in each strip. The picture has the bottom set cut off, but it's the same thing. A single LED does not come on..

Conventional wisdom says that I have to replace the entire array... But I wanted to get some confirmation that, because a single LED from each strip has gone out, there isn't any other factor at work here...

The factor at work? Shit Chinese LEDs that last about a thousand hours before popping. The other LEDs are still lighting because the LEDs failed short circuit instead of open circuit.

If you look at the bottom side of the strip, do you dark brown area due to heat where the LEDs are on top?

So, in other words, nothing out of the ordinary??

Upon closer examination, I did confirm that an entire strip is now bad..

I coulda swore it was good initially, but it's possible I missed it..

But if I switch it out, it's likely I'll still have a bad LED on each strip...

Most of the bad strip that I found with shorted LED or over driven will have dark brown area showing the sign of over heat.

Hmm, E60-C3 is the TV model number, I wonder who makes the LCD panel.

Yea, that's the only tag on the frame...

The serial number on the panel sticker would lead me to believe it's a Sharp. Strictly guessing.

UPDATE..

I got in 2 replacement LED strips..

On the plus side, the LEDs DO stay on...

On the down side, several of them blink and then go off...

Looks like I'll be replacing the entire LED array

Thanx to all for the replies...

Re: VIZIO 60" E60-C3 Bad Single LED In Each Strip

UPDATE II...

Got the replacement LED strips in and I can report complete success... Maybe...

All the LED strips come on and stay on.. No bad LEDs in the array...

BUT...

At power-up, all the strips come on bright and steady.. After 10-20 secs, some strips dim and some strips don't.

I have seen this before on other TVs I have broken down where the whole array will dim after a few seconds or so, but never seen it go piecemeal like this..

Is this possibly some sort of screen-saver process?? Or am I looking at a Power PCB issue??

I suspect you're seeing regional dimming of a "No Signal" box floating around the screen.
Common, and the effect looks awful, but it lets the mfgr claim some stupid contrast ratio performance figures which aren't even remotely realistic.

Re: VIZIO 60" E60-C3 Bad Single LED In Each Strip

OK.. That's what I was hoping it would be..

OK Now I begin the arduous task of putting it back together..

Not looking forward to that..

Thanx for the reply...
