Question about Televison & Video
There is backlight, but no picture and no sound.
Depending on the model, if the backlight has come on but nothing else then the main av board has fun into a fault, some models have a rest sequence to use on the original tv remote to reset to factory settings, if your model does not have this feature, then turn the power off for 10 min and plug power on and holding down the either of these, power button or menu and select. some times these work to reboot.

make sure the caps you installed are the exact replacements. Changing voltage capacity or timing will cause the circuit to fail.

Most likely this set has an "integrated" inverter, as most samsungs do--and this DOES sound like an inverter problem. Make SURE thought, there are no more bad "10 volt" caps on the power supply...ALL of them need to be replaced no matter HOW they look.

I have been having the same problem with my LG. people say there are bad capacitors on the power supply board. I don't have the know how to replace them and don't have the money to pay. I can get mine to work by blowing hot air with a hair dryer into the back of my tv through the vents over the board. Heat it up for a couple minutes and turn it off and then back on and the picture comes back. I just never turn the set off now.

This TV comes with a remote that connects to the TV via Bluetooth. It
remembers which equipment is connected to the various inputs, and
automatically changes the controls to match the input equipment - really
nice! I found that it will control all my equipment, and since it
works via bluetooth, you don't have to have direct line-of-sight to the
TV. Wish that the bluetooth part worked for my satellite equipement too!
Programmable remotes will operate this TV, but depending on how old
they are, they may not be able to hit all the features of the tv - our
older directv remotes will operate the basic features, but only the
newer models will change the input source - so you may want to use the
remote that came with the TV. We have smaller kids, and wanted to limit
their use of the tv remote, because it has a slide-out keyboard similar
to those on some cell phones to make posting to facebook (one of the
apps that comes on the tv) easy. Since our youngest is 5, we thought it
might be best to keep that remote out of harm's way.

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced.
