Thx bro

I started out replacing individual backlights, until I realized when one of them goes, the others will soon follow.

I have a similar problem on my tv but it’s like not black or anything it’s the entire picture moving up down type flickering … would you know what could be the problem ? I wanted to chat with you if you were free

good tv

[@isaacsuedel355]

Your link for the leds says out of stock any other leds you’d recommend?

If it’s the main board can it be fixed ??

I bought a new led strip, but I have a problem with the power supply. On the instrument it shows 255 volts on the Led output. The diodes get very hot in just a few seconds. I don't believe that they would last until I lower the voltage in the menu.It is the same TV model Have you had such a problem?

[@NewsonsElectronics]

they do heat up

[@TieMrShirt]

@@NewsonsElectronics Yes, LEDs heat up immediately!

[@NewsonsElectronics]

255 sounds a bit high do the math 1led is 3volts how many in series.

[@TieMrShirt]

@@NewsonsElectronics I calculated, 20 diodes per series need 60 volts! In one of the videos, I read that the led part is for that 6-volt TV. If it works that much, I needed the maximum to be 180 volts! I have no idea what to do except reduce the voltage somehow. I'm not an expert in this, but I have to solve something already, when I already went to repair the TV.

[@threestars9788]

_If there is no back light ,is changing of strips only a solution ? Can't the TV be repaired without changing the strips ? Are all strips required to be changed as per some technicians because changing of few strips affect functioning of other strips subsequently. ? Kindly clarify

[@NewsonsElectronics]

just replace the broken leds

[@threestars9788]

@@NewsonsElectronics u mean led strips right ?

[@MrNew-us1lg]

@@threestars9788 no just a single led not the entire strip
