Philips PUH6101 (TPL16.1E LA) Backlight repair

[unimatrix93]

Hello everyone!



I need some help with identifying the LED SMD types on this TV's backlight strips.

Two strips showing very little dim light, so I want to solder new LED SMD's on those, but I'm not sure which size of SMD's I need to order.




I tried to find LEDs for this TV model, but I only found complete strips which are expensive:

Based on the pictures it's 3V 3535 or maybe 3528 LEDs?
Like these:

I want to make sure I order the correct LEDs but sadly I don't have phisical access to the TV at the moment so I can't identify it further.

Thanks in advance!

Desolder. Look at pads. Big pad and small pad polarity. Measure dimensions.

I have a strip from a different Philips TV here and they are 3535, however the bit that lights is smaller than your banggood listing. Having the wrong shape/size could possibly cause an extra glow on the screen due to the lens shape.

Thank you everyone!

Wish I could check the LEDs on the TV but the guy wanted it back for a few weeks, so he has a TV

I wonder If it's 3535 size. Should I order in that size?

You can get them on AliExpress or cut up a strip to use.

I contacted a few sellers on ebay and on aliexpress regarding the LED sizes on their strips I hope they will tell me... Wish I could access to the TV to check them.

It doesn't matter what the size is. Only the voltage. You are not putting them on the original pads.
