Thanks for doing this at night. When you do your videos during the day it is often useless video due to the brilliant outdoor light on either side of the set you have set up as a backrest. Congrats on this fix! Wonderful picture from what was headed to recycling.
It always makes me smile to see that the screen comes back. Great fix Allen. Can never get fed up and always brings a warm pleasurable feeling doing this repair. Customers thinks it’s black magic LOL Regards, Brian 👍👏🏴👍👏🏴
A quick FYI, on some screens you can fit the LGP (prism sheet) upside down so the melted bit is at the top and not the bottom, just make sure the etched surface remains towards the front and they are usually much better, for a cheap repair.
I've seen a lot of tv's fixed by deliberately removing signals that the manufacturers thought it needed, only seems to work with tv's, I'm sure if i pulled a stick of ram from my pc and taped over some pins my pc still wouldn't work, or disconnected some of the injector wiring on my diesel van, pulled a few cables from my consumer unit to find my hall lights dont work, why are tv's working with things missing it makes no sense....
These 50" models will work 99% of the times with ckv line blocks and picture is 100% perfect.this is caused by keeping the tv on still pictures for long.if you check ckv line with multimeter every time you pause you ll see voltage increase which causes the film diodes to burn in side of the screen.
I found 58" TU from an e-recycle and blocked one line on the ribbon, The picture is great and everything, but with UA-cam half of screen loses green color, BUT only on UA-cam content, advertisements with UA-cam are fine, great picture otherwise. That is the strangest fault.
Hi Allen, Can you do a video on screen lights, back light vs edge light , i have panasonic tx58ex700b lights shading at the bottom, was suprised it had led strip at the bottom? Great video by the way, paul uk
I bought a Vizio back in July of 2020 I have here had the issue that the Sony had. I'm thinking that this is from the part that both LG and Sony buy. My TV was assembled in Mexico. TV's that are assembled in Mexico probably could have different parts made by different suppliers. I know Sony buys the parts from multiple suppliers and they only assemble their TV's.
White LEDs are actually blue, but have a phosphor coating or plastic that contains the coating that converts it to white. On these, there are probably plastic lenses over the top of the LED chips. If they fall off (they are glued on usually), the color will show as blue instead of white. You'd have to perform surgery and remove the LCD glass to expose the backlight chips to fix it. Not impossible, but you have to be careful.
I had a similar issue with my Lg. Kept resetting. Found the ribbon cable was not clipped in properly so it was rebooting to try to connect to the network repeatedly. Was a very easy and costless fix. By the way I found the solution here on UA-cam.
Hi I have a issue and I really need help I replace backlight in a samsung UN65TU8000FXZA after installing the new light I test all with my backlight tester all work fine. After putting the tv back and plugging it in the backlight is not powering on.The powerboard is working because I'm getting power about 280v for the backlight. So my question is what could be the problem could it be the white connection between the powerboard and the lights. I forgot to mention I test the backlight using my backlight tester and the backlight work. I have some needle leads to my backlight tester so that's how I was able to test inside white connections.
LCD screens have always been unreliable just as plasma screens were but to disconnect data lines that inform the micro their is a fault is downright dangerous if this set set on fire in the middle of the night someone could be seriously hurt or even worse please don't bodge like this it's unsafe
Manufacturers are getting lazy where Quality Assurance is concerned. They also fail to stand behind their products (true also of LG refrigerators). I've owned a 47 inch Samsung flat screen since 2005 and it continues to work perfectly. Yet, when I 'upgraded' to a Hisense 65H9G the TV lasted less than 4 years. The fault turned out to be a failing motherboard, causing continuous reboots followed by a shutdown. Root cause was super-cheap, low quality memory. Anyhow, this problem is so common on this TV that replacement motherboards are unavailable. Fortunately there are several repair services who can tackle this issue, but I find it sad that Hisense is completely unwilling to address the problem or even issue a revised motherboard for repair. Apparently manufacturers seem to think it's entirely acceptable for their huge flat screens to last just a few years.
I own 2005 46 inch Samsung as well. I have thought to upgrade it, but unless I am going to spend $1500 to $2000 I wont bother. These cheap TVs are designed to last 4-6 years. I paid $100 dollars for it when my newer 2011 Samsung died.

The bootloop is caused by a bad TCON PMIC, which is a screen issue. Disconnect the LVDS to see whether it stays on.
There is no LVDS in this model of TV, the T-CON is part of the main CPU.
@@tyronenelson9124 However; disconnect the connection from the mainboard to the panel and see, whether the bootloop persists.

Hi Allen,what will the tv not do correctly,know the pins have been covered ?

Nice picture,good fix

Is it true ? Do these "smart" TVs - have a camera inside their gubbins ?

Got a 49in with same fault
What is it with these Samsung screens, LCD panels never used to fail so why are they? that's very suspicious.
@@tyronenelson9124 yes the company who made all of these has now gone bankrupt. No surprise
@@allenfleckney5969 Interesting.
result there. hope it lasts
nice you can replace your other worse monitor one
