Re: Samsung lnr408dx/xac, no image, backlight ok, changed 2 capacitors

Just to say thank you... The TV's working and the humming hissing sound disappeared when I plug a vga/hdmi source.
Here's my family watching netflix on it :

Thanks again !
Ps: that cp fuse looks like a programmed obsolescence from Samsung. What do you think ?Re: Samsung lnr408dx/xac, no image, ...nd the humming

Re: Samsung lnr408dx/xac, no image, backlight ok, changed 2 capacitors

God this fuse is tiny. Do you have a way to solder it without covering the whole chip with solder ??!! I searched the whole internet and youtube and found nothing to show me how to do it.

Thank you.

Ok. First thank you for your help.
I did what you asked. Here's the result:
5.38 on the left side and 0.24 on the right side. I presume this is in Volts.
Also:
The backlight is definitely working. Here's a picture i've taken of the open Tv in the dark :

But, i noticed a hissing sound. I made a recording of it with the power on and off chime in case it could help to diagnose another problem. Here:...

Thank you for your reply. I managed to access the T-con board and I have included a picture here : [url]https://www.dropbox.com/s/pyic7mjcrm8ppy6/2013-03-16_13-17-48_HDR.jpg[/url]
I don't see any fuse though. I finally bought a multimeter and tested every removable fuse I could find on every board but every one of them (there's 4) seems to be fine.
Here's a picture of the whole set :

Hi,
I found this 40'' tv (Samsung lnr408dx/xac, made in 2005) near a trash in front of an electronic store and brought it home.

I plugged it and got a little electronic melody and the backlight seems to be working since there is a little glow that appear but there is no image. It's black. I plugged a VGA connector and connected it to my computer and Windows recognized the screen as a Samsung TV. So some electronic seems to be OK.

After looking on YouTube I learned about the bulged capacitors problem. I opened the TV and yes there was two small bulged capacitors...
