The LCD/LED panel has broken. This is not worth an attempt to repair.
The replacement panel will cost more than a replacement TV. Send it back
or otherwise dispose of it.

Or sell the boards on ebay. List the model and part number for each board.
You may make enough to buy a new TV.


Hey, I listed three PCB's from the TV on Ebay on Sunday, I got offers
on two of them today. I ask $65 for each pcb, I got a $50 offer on one
and a $45 offer on the other. I accepted both rather than sending away a
buyer. Fedex has them now.

That's the good news... here's the bad:

A lot of people do their own diagnosing or follow someone's (alleged) success on youtube and always assume their TV has the same issue. What happens is they buy the wrong board, or the TV doesn't need a board at all if the display itself is bad or has an open LED in the display or a wiring issue inside.

Recent Samsungs are known for LED failures. It would not surprise me if you don't get a return request on one or both of those boards. My dad always told me not to count my chickens before they're hatched.

Good luck.

This was an LCD TV for what that's worth. One board was bought by a TV
shop, the other by an individual.


Selling to TV shops is the best way to sell boards, but even they sometimes make a guess. Paypal is notorious at siding with the buyer on just a complaint, reasonable or otherwise.

I think the TV shop just made a low ball offer, if it is accepted he
can stock it.

Yes, your TV was an LCD, but other than the extraordinarily rare OLED, most TVs are LCD.

Just correcting the LED label from the previous post.

The first LCD TVs were simply called LCD as opposed to the other flat
screen tech at the time: plasma.

These TVs used CCFL tubes for back light illumination as LCDs are shutters and don't generate any light (unlike plasma and CRT).

Later, when manufacturers found a cheaper way to build back lights, they started using LED arrays to provide the back light for the LCD panel. These TVs are generally called LED, but they are still LCD TVs and use the same screen.

In the service trade, we refer to earlier LCDs as CCFLs and later ones as LED TVs.

The point of this is although you didn't post a model number, that model looks like an LED LCD, not a CCFL LCD.

It had 14 CCFL tubes running across the back panel of the TV.
I also have the inverter PCB for sale, but at the end of a month I
will probably dispose of it.


> If it is an LED back lit TV, LED failure is common and when an LED opens, there are various symptoms, most of which duplicate bad power supply or bad main boards.
No backlight LEDs to fail.

A BIG contributor to backlight
failure is the setting for it! Most
people do not go into the menus
for these flat panels, and just
watch it in default settings -
typically 'Vivid' or Dynamic
mode.

I calibrated my LED set last
year, starting with the backlight
lowered to halfway. Final
setting was 8/20, using Samsung's
scale. It is still plenty bright for
viewing where the TV is in my
house, looks awesome at night,
and neither myself nor anyone
else watching it has complained
of eye fatigue.

Moral of the story: Unless the TV
is intended for use outdoors on
sunny days, or on the sun deck of
a cruise ship(!), there is no reason
whatsoever to leave that backlight
at its maximum setting. This is
akin to leaving the Contrast
setting on an old tube TV cranked
up all the way. Which is why so
many of those hit the dump
prematurely.

The moral is correct will be lost on just about everyone. The TV's default is 100% back light right out of the box and will revert back to 100% if you sneeze loudly anywhere near them. When I first started doing LED array repairs I'd demo the proper way to adjust back light, show them where I set it and why, and I'd still see some come back a year later with LED failures, and the back light setting defaulted to 100% once again. Try this: put your back light to 50% in custom, then move to vivid, sports, theater etc. Return to custom and you'll find all your settings where you left them, *except* the back light which is now magically defaulted to 100%. It seems the engineers think people like the light pollution that bleeds through dark scenes and destroys the black level..

It's even worse if the customer chooses "demo" instead of "home" when they first perform the out-of-box procedure. The "demo" mode cranks the back light another 20% over the already too high setting. If someone buys a demo off the wall at Walmart, the TV has maybe weeks or months left to live.

So, every LED repair I do involves modifying the drive to the array, usually I shoot for 40% reduction in wattage. Most mods involve changing the source resistors on the drive mosfets to raise the feedback dc to the controller IC. Some top of the spectrum brilliance is lost but the black levels improve dramatically. It's a trade off that also virtually guarantees no returns to me.

Only one person came back and questioned the brightness of the TV (a Samsung)that I repaired. I explained what I did and why, and expressed surprise that he picked up on the picture and he was the first to do so. He told me he had two of the exact same model in adjoining rooms, and saw the A-B every day. I told him I could certainly undo the mod and explained the trade off in life, and he said he'd keep it that way.

Where were the cry ins when Obama got elected ?

Where were the blocked highways when Obama got elected ?

Who was kidnapped and forced to drink toilet water when Obama got elected ?

Who disrupted public speaking engagements when Obama got elected ?

Don't try to sell that shit to a grown Man. Liberals might buy it. You know why most conservatives are older ? Because they learn in life that liberalism does not work.

ERRRR! Not on my 2015 Samsung
smart LED! When I cycle through
all those modes back to custom,
or Movie as I use(least background
processing of picture), the backlight
is right where I left it.


Guess it depends on year, model,
and even size of Samsung.


So that customer in your last example
agreed not to go back to torch mode?
Good for him! There is hope afterall.

I think most conservatives looked at Obama, looked at Romney, shrugged,
and figured they'd be better off anyway.

Then called him a Kenyan Muslim for 8 years.

The reason people were srs upset over Trump in a way that was different
than Obama is Trump made it a point of his campaign that his presidency
would be dedicated to exacting mass revenge on the most vulnerable
people in society on behalf of the (imagined) slights his base has
"suffered" at their hands.

Should they not have taken him seriously? When someone says directly "I
am going to fuck you" I guess they should just relax and see how things go.

I'm sure conservatives thought Obama was going to fuck them, too.
Problem is that the definition conservatives have of being "fucked" is
if the government doesn't kiss their ass and do exactly what they want
100% of the time, particularly on matters of religion, taxes, and not
expelling every non-white person in the country.

> Don't try to sell that shit to a grown Man. Liberals might buy it. You know why most conservatives are older ? Because they learn in life that liberalism does not work.

I think it comes mostly from feeling bitter about girls not liking them
very much when they were younger.

I didn't especially. It's good she's thinking, but that's all. It certainly doesn't warrant any generosity. And I'm sure she has quite enough of her own. When I hand money out it's where it's going to do something truly useful.

True story: I was sitting at a restaurant with a friend who has a Sony LCD 50" that I "calibrated" (eyeballed) for him. There were several TVs running and the one near us had a baseball game on. The TV was a Sharp Aquos 60" that had a picture so cartoonishly garish that it was truly offensive to the eye. Not only were the LEDs (apparently) cranked all the way, it also must have had every "enhancement" in the picture menu checked off.

So my friend, impressed by what he was watching on the Sharp(!), asked if I could get his Sony to look like this Sharp. I told him in my best deadpan that even if I screwed with every adjustment, I couldn't possibly get the Sony to look that bad.

His look of complete confusion led me to ask him if he ever saw grass that color (a bright fluorescent green). I asked him if he ever saw a black shirt have a blue underglow to it. I explained that his Sony was adjusted to give as close a representation as a view through a window, not change the content. He finally saw what I was talking about. I didn't bother explaining the artificial black level "enhancements" this TV had, as that's best done by an A-B demo.

But go to any store that has a hundred TVs running. The one cranked to stupidity is the one most people will think has the best picture. Kind of like the old "sizzle and boom" EQ settings people like to adjust their stereos for.

LOL!

I wonder if this is the case in stores in
countries outside the U.S. I know it
was in one electronic emporium in
the Philippines. I eyeballed a 4K OLED
to sane levels as you did, but within
5 minutes of turning my back the sales
staff had the set back in torch mode!

No WONDER consumers have no
concept of accuracy when it comes
to a TV picture, and manufacturers
are largely to blame.

That's the good news... here's the bad:

A lot of people do their own diagnosing or follow someone's (alleged) success on youtube and always assume their TV has the same issue. What happens is they buy the wrong board, or the TV doesn't need a board at all if the display itself is bad or has an open LED in the display or a wiring issue inside.

Recent Samsungs are known for LED failures. It would not surprise me if you don't get a return request on one or both of those boards. My dad always told me not to count my chickens before they're hatched.

Good luck.

After I sold the first two pcb's I decided to list the third pcb.
It sold, but, it happened, the third pcb I sold is being returned.
Customer (a TV repair shop) says 'did not fix backlight problem'
The board worked when I removed it. I suspect poor trouble shooting or
I'm getting back a bad pcb. I did mark my pcb with my intials, so I'll
know if I get the same pcb back.
I posted a picture of my markings to ABSE and to my dropbox account,
this morning I also made a Ebay listing showing the picture of my
markings on the pcb. I used a very high price so no one will bid.
I hope I get back a different pcb. Today is the last day the seller
is supposed to ship it. No notice of shipping, I provided notice to
return on 6-28-17, he has had 6 business days to return.

A lot of TV "repair" facilities are guys we call "trunk monkeys"; repair shops operated out of the back of a car. These guys have no training and no state license, but just swap boards around hoping to run into a repair.

Yes, it was indeed poor troubleshooting on the buyer's end and now it's aggravation for you. Samsung LED failures are epidemic, and the repair shop should have known this. Most shops built their own LED testing tools years ago, but now anyone can buy a tester for LED strips that will light even give a voltage readout of the run voltage of any given strip at the tester's preset current limit, and do so without disassembling the display.

It's possible that the buyer made the return request in the hopes you would credit back the money and tell them to keep the board. It wouldn't surprise me if you don't hear from them again.

Too bad you also didn't remove the LED strips from the carcass before scrapping it. These bring good money and are in high demand.
