Found Samsung LNR328WX/XAA thrown in trash. After powering up backlight lids for about second or 2 and shuts off. The backlight board part number 19.26006.104 appears to have one bad transformer. It has marking 4001K511010 (GP). Can anyone point me where to purchase one of these. Boards are also available but I would like to repair board just for fun.

Re: Samsung LNR328WX/XAA
What resistance measurements do you get on the bad transformer?Originally posted by ned1 View Post
These used to be cheaper as I bought one myself. Something like $6 or $7 USD + free shipping, but prices have gone up significantly.
Only two sources that I found. It might be cheaper to buy the inverter board and have spare transformers?
$15 USD + $5 s/h (used)

$21.99 + whatever for s/h

Re: Samsung LNR328WX/XAA
Thanks for your help. I ordered replacement board since it is cheaper then just buying transformer from China for $20. The one side of transformer is completely open while other side reads 1.5K. See the picture of transformer removed from circuit.Attached FilesComment

Re: Samsung LNR328WX/XAA
You can recoup some or all of your costs by selling some of the good/spare 4001K for $10 USD + free shipping (within the USA) on ebay??Originally posted by ned1 View Post
