Re: Samsung UN46EH5000, No Backlight

so i got the leds from aliexpress and soldered them on. it measured 3.1v like the OEM's but once i put the plastic cap on, it wasnt as blueish like the others. it looks slightly less bright too. the bottom of the led's design also didnt match the positive and negative square design but it did solder on using solder paste and heat gun. from another youtube video someone suggested using this [url]http://www.digikey.com/product-detail/en/lumileds/MXA8-PW50-0000/1416-1096-1-ND/4031760[/url]

i'll give it try and hope 5000k will ma...

Re: Samsung UN46EH5000, No Backlight

i took the strips off and used a heat gun and heated it from under the strip. couple of minutes later the led on top got hot enough to move with a tweezer. there were no burn marks left at the bottom either. still waiting for the led's from aliexpress.

heres a youtube video I'll try to repair with except I'll use the heat gun from under the strip to not damage the led's. [url]https://www.youtube.com/watch?v=0uBhca7zyXI[/url]Re: Samsung UN46EH5000, No Backlight...gun and heated

Re: Samsung UN46EH5000, No Backlight

i saw those samsung leds from aliexpress but the size is slightly bigger than the ones on the strips. my measurement show 3.5x3mm. the samsung led is 3.5x3.5mm. anyways, i will order the samsung led and try to solder paste it on. thanks for your help.

Re: Samsung UN46EH5000, No Backlight

any luck in replacing the led's? i bought a led tester for $40 on ebay and it shows 5 leds are out. i managed to take out the leds with a heat gun but dont know what led's to buy. i see several on aliexpress and digikey but not sure which one to order. from using the tester, the leds are reading 3.1v. these from aliexpress seems very close in design and great feedbacks but not sure about the specs.
