Hey guys and gals.... I was just given a three year old Samsung TV (Model LN-S3241D).











The issue with it is that any video source will degrade on the screen.
The Picture starts off nice, bright, and clear and slowly degrades to a
dark black image in which you can barely see anything. Total time for
the problem to begin is about five minutes.





If I'm running a DVD player and it happens and I turn off the DVD player
but not the TV. The image comes in bright and clear once I turn the
video source back on again and the screen image will degrade again.
Tried different DVDs, video game systems, signal inputs for cable TV
(Cable box, direct coaxial cable feed, etc....) I don't turn off the TV
to reset it.





What would be the goes of this and what is the possible fix. This TV
didn't cost me a cent so if I can get it working for free or cheap works
for me.



I like free and cheap.... so come on guys. Help me out.

Probably backlight power supply dying.





EDIT: found this http://www.fixya.com/support/t4282295-samsung_ln_s3241d



Has something to do with a heat issue involving the backlight power supply.



I have an older 50in Pioneer Elite plasma that had thermal issues. Pulled the back off, cleaned dust bunnies out and hot wired the fans to run full speed whenever the display is on. Has worked fine ever since.
 

Any way to fix it?

Sounds like a bad inverter to me. If you aren't experienced in replacing TV parts, scrap it.
