A few days ago, the user brought a 32TCL LCD TV, saying that a master had checked that the backlight was broken and could not change. I got this and asked if I could change it. I was so eager to ask for a price. I definitely promised that I could change it. After the quotation, the user also agreed. Boot check, bought a light bar on the TB. I have arrived today and I can start work. In many posts, I saw many amateurs who dare not change the light bar. Today I will share the process of changing the light bar with you. I hope I can help you.
