A good article throwing 'light' on replacing lights! Something I never venture to do, because I have put a limit upto panel. Anything from T-Con board to panel, I never take up! But good to add up knowledge, especially when it comes from veteran like you!

Albert; I hate to work on CCFL tubes on TV's. I would rather work with LED lights instead. I agree it is time consuming but I love doing this kind of work which I found rewarding in many repair cases.

Beh: yes, I buy a lot of broken TV's from Customers who throw their TV's away and sell parts for good income. I get a lot of LED strip but there are a lot of models out there and keeping up with that is a lot of work nd time consuming.

some times the only way is to buy a broken panel tv and sacrifice the parts to other ones and by experience, the best way is: if you have a bad LED replace all strip, not just that one. well done and thanks.
cheers

Kostas: yes I am very aware of that but the damage was great and I found it easier to replace the strips instead of the damaged LED light. have a blessed day

Repairing the Led backlight strips is still a lot of work and they cause a lot of problems compared to the old CCFL backlight tubes. So good job and gaining another happy customer. These timeconsuming repaires will be over when OLED panels have become common goods. They require no backlight and each individual pixel is extremely energy-efficient too. Since only today's LED TVs need a backlight to produce brightness, the future is probably brighter in both ways.

Hello Waleed.
You could replace the bad leds with other ones.There is no reason to replace the whole strip of leds.
I have a stock of all the leds ,eg 2.7 volt,5 volt (LG models) .It is very easy to order online.They are very cheap.
Then you could replace individually.But you have to take care about the reflector of each one to attach it with glue.I use gun thermal glue.Also because usually the new leds have stronger light it is better to use black glue around the reflector and make a black dot at the center of it with a marker because there will be brighter spots at the lcd.
