no there is not, the pads are there to solder wires to> when you cut the strip and you have more than 80 leds then power from both sides is the way to go.

if you want clean/nice colours this is the way to go> reason is that current which flows trough a LED has a huge impact on the colour the LED will provide. The less current and the more the colours will differ, because every LED is in fact a mini resistor the current can not flow at certain point any more and you get discolourations in the rest to the end of your strip.

i will always recommend to power from both sides if the strip is in one piece.

note; and ofcourse the PSU is also really important > a clean, steady and good rectifier/PSU does wonders for a ledstrip/PI

my friend, I really dont know what i did here, or what happened, but the led strip is working 100% now.

im really surprised because I didnt do anything beside restarting it.

really WTF.

Really thanks for the reply!

yes, of course.

this goes for if you had the strip only shortened at the end to match the lenght of the tv

You have your begin of the strip> it has a connector thats connected to the solderpads

now at the end where you had cut the strip, you need to roughen up the solderpads and solder on +5volts and GND a wire,

VCC = +5volts

GND= ground

these wires you connect also to your powersupply.

with this setup you are powering the leds from both sides which helps the discolourations

ok I think I got it.

I suck at soldering, and I think I lost my tools also

Do you know if there is another way to do it without solder maybe?

i have a tip: power the begin and END of the ledstrip with 5volts and GND, bring those to your PSU.

ledstrip isn't gonna need that much, 10A should do it.

Pi uses around 750mA

ledstrip uses around 5A

Hi my friend!!

thanks so much for your help.

Can you detail a little bit more how can I do it? I am not an expert in electric hahaha

Hi guys, i recentely installed hyperion on my TV, but some leds (final ones) does not light up when coloring, but when I check the RGBW checkbox, it lights ups.

I have it running on a raspberry pi 3b+, a power supply of 5v 10amp, my Tv is 65'', wich calculating leds is something like this.

top: 80

left: 40

bot: 80

right: 40

I registered this infos on hyperion software and suggested me around 16Amp of power, is this the problem at all?

1- Testing effects, the led lights goes all ok until reach this point:

2 - this is the ambilight screen capture with RGBW on, wich apparently the leds lights up oO

3 - ambilight screen capturing, leds on the left upside not working

4 - when rgbw option on, it works
