Re: Samsung LE52B620 - Flickering backlight
The replacement board arrived last week and the TV worked after I did the swap.
I ordered some [URL="https://www.ebay.com/itm/283186683036?mkevt=1&mkpid=0&emsid=e11050.m43.l1123&mkcid=7&ch=osgood&euid=100c8e2449b24a9fb87712ab1a437065&bu=43083089027&osub=-1%7E1&crd=20210914032750&segname=11050&sojTags=ch%3Dch%2Cbu%3Dbu%2Cosub%3Dosub%2Ccrd%3Dcrd%2Csegname%3Dsegname%2Cchnl%3Dmkcid"]22pF 6KV high voltage ceramic capacitor [/URL] from ebay to replace the ones...

Re: Samsung LE52B620 - Flickering backlight
Hello Lotas,
I bought a cheap multimeter and checked the resistance of those spots and the readings were the same. (23.8 & 0.4, see attachment)
What would be the next thing to check? also thanks for all the help so far!...Leave a comment:

Hello Lotas,
Thanks for the suggestion.
Ok I reflowed the solder in these areas.
If I turn the TV with the mainboard unplugged, the blacklight turns on for about 5 seconds and then turns off.
With the Mainboard plug, I get no backlight when turning out the TV. (I can see the menu's if I put a flashlight to the screen)...Leave a comment:

Samsung LE52B620 - Flickering backlight
Hello All,
My Samsung LE52B620 started to have backlight flickering about a year ago, it would only last for about 10 mins and then the backlight would stay on.
about a month ago the backlight flickering is constant and does not stop.
I think it's a problem with the power supply board (BN44-00267b) or maybe the backlight is dying?
I checked and all the caps look to be fine.
I do not believe it is a problem with the mainboard, since I unplugged it from the power supply and the backlight came out but still flickers.
