I'm posting this not because there is a problem with this TV, but to help some with similar issue. I have used this forum many times and it just helps me to learn more.
The symptom of the TV was that it would turn the display on for just a split second. I could see it was on, but there was no backlight.
I suspected part of the BL was out.
Then I noticed a slightly bulged cap. After replacing it the TV works perfectly.
Thank you for all the help I find here!

Vizio E48u-D0 not turning on, Pwr LED on and off
Hi everyone.
Working on this LED TV.
TV started with sound issues, would make like interference noise. One day it just did not turn on anymore.
Replaced the power board already but no change in symptoms. TV makes no sound, has no picture but pwr LED is on. Upon remote power on, the pwr LED goes brighter and then slowly dims to off. The pwr LED does come on and goes off infrequently.
On the main board connector J4 at top of board shows 18V on pin 1-4. I only measure 17.5V. Would that be an issue?
Pin 9, PS-on, has no value printed but I measure 3.3V.

Re: Samsung LN-S3241D, powers up, has sound, has image, but no backlight
It is the F1 fuse. I bridged it and now have backlight. TV works.
Thanks you bud.
Now where do I find this fuse, partnumber, or can I just leave it bridged?
Thank you again, great call!Leave a comment:

Re: Samsung LN-S3241D, powers up, has sound, has image, but no backlight
Thank you for the response.
If I see this correctly it is the one with a marking "20" on it.
It does not show open with the ohm meter.
How do I check this the correct way? And could I bridge it?
Thanks again....Leave a comment:
