If I lay the panel screen down on the floor, won't I have access to the LEDs once I take the back off completely?

Saw this post after I edited my last one.
Ok,thanks budm.
This being an Emerson, is it worth fixing it?
$75 for the led set and I spent $25 for the TV.
Or should I not bother?

You can do it for repair experience, now you already know how to find out which string works as which one does not work.
I would open the panel and test each LED to see how many are bad,.

I need all those or just some?

Two already went, and who know when the third one will go, the main concern is that how the use one were used, if they were driving them on hard which is typical then do not expect the used one will last either.
Once you replace them you should also turn down the backlights level on the on screen user menu.
At this point it is a gamble, I would do all 3, it is 50" panel which will NOT be EASY to disassemble.

So if I'm understanding this right, there are 3 rows of LEDs.
And you believe 2 are out.

I don't know. The listing says he has 3 of them. Should I ask? What would I need. 2 left and 2 right?

Oh, one of those LG Innotek LED which commonly failed.
Expensive.

I do not know what kind of LED strings set up are being used in side the panel.
Can you find the make and model number sticker on the LCD panel?

Re: Emerson LF501EM5F shuts down right after turning on.

Can I purchase/ replace those string?

Re: Emerson LF501EM5F shuts down right after turning on.

That does not make sense for the Vdrops on the return to be that low, but the bottom line is that we know the other two strings are not lighting up.

0.81 just checked it again now it's 0.83.

[budm]

Re: Emerson LF501EM5F shuts down right after turning on.

Red 60vdc, yellow got as high as 9vdc, blue got to 80vdc, grey drops below 0.86vdc when turned on, black 80vdc and white 0.8.1vdc

BTW, is that 8.1V or 0.81V?

Re: Emerson LF501EM5F shuts down right after turning on.

Yes with the yellow out also.
I out the grey back in just now too and the screen it lighter than it was white yellow and grey out.

[budm]

Re: Emerson LF501EM5F shuts down right after turning on.

Yellow out, white in, bottom half is lighter than top.

So just the White one in place you do see the backlights come on for seconds?

Re: Emerson LF501EM5F shuts down right after turning on.

Not even a flash for seconds?
Remove the Yellow, and put grey back in and see, if still nothing remove the grey and put the white one back in and see. Need to know which one lights up the screen at least one of them will come on for seconds.
I will need to trace the pins on the connector again.
