Just did one myself 3.3v rail capacitor. Diagnosed using hot and cold on capacitors to pinpoint problem. After replacing it worked and bad capacitor read correctly at 47uf but I guess had bad ESR. It wasn't bloated either. Can never trust an electrolytic like a politician.

Is the back light 3 rows each 7 bulbs connected two rows in parallel and one in series? If all bulbs in series the voltage required is 21x6 volt= 126 but it lits up at 70V hence my doubt.

they all connected in series, the LEDs are 3 volts

Sir, a personal question? Are you a member of an IP Tribe? Just listened to the background conversations and heard some accents that sounds familiar. Thanks.

Please change all the led strips otherwise the same problem may occur soon (because other led bulbs life will be reduced so same problem will occur again soon) Thanks

Multi tester can test it

Your diagnosis bit confusing 1 St you said backlight not glowing & Measured backlight voltage is not boosting then why are you going to 12 volt & 5 volt lines instead of backlight section.

Sometimes addressing the visible issue, like a bloated capacitor, is the first step in troubleshooting. It's essential to fix any obvious problems before diving deeper into more complex or hidden ones. This can help prevent further damage and ensure a more thorough inspection of the system.

Good job
