Thie tv i tried to remove the scraches on has failed backlights its a 2019 phillips 55 inch, i tried t cut as yes used on my car headlights the issue is i think the lcd has a antiglare coating on like someone else mentioned, as it has left some patches on the areas i tried over the scratches i might try doing the whole screen so it matches but then once i repair the backlights im wondering how the picture will look...

they sound ok then (i was only asking as i had i strip in a set that was using more volts and amps i replaced that strip set worked fine) so oredered a whole new set maybe worth trying a replacement mainboard in yours set as new firmware not solving the issue.

Can you power each strip seperatly and see what each strip is using voltage and amps wise...

As diah ritely says yes remove screen and check the backlights (98% of my repairs lately have just been failed backlights)...

can you take some pictures of the top and bottom sides of your psu and upload them thanks...

you may have to jump some pins to get the missing voltages if your just bench testing the psu (im not sure which pins though)...

Hopefully it was just a loose/dirty cable and re seating it has solved the issue all you can do now is keep it on test turning it on and off at time too hopefully the issue has now been resolved....
