Hello there,
I believe the Audio/Video Inputs/Outputs could be going out .
If you are using the HDMI try the Component cables and connections or AV cables with the S-video
if you swap the cables around and the problem is still there let me know and we try a few more steps thank you and don't forget to Rate

Hi,
this could be a problem with the power supply in the tv, it is common especially on some Samsungs
and specific repair kits are available quite cheaply if you have good
soldering skills, this can also apply to many other Flat Screen TV's .
Usually this is caused by capacitors that have
dried up and split, you can normally tell as the capacitors are bulging
on the pcb, you can get them in a kit as I said eBayer's sometimes do them
or you can buy them indivually from a good electronics components
supplier, make sure you get the correct values for each!! marked on the
side of the capacitors in xx/x V, xxx/x uF and 105oC. (the x's represent numbers)
The picture
below shows the type of theing that happens, the brown ones are
bulging/split on the top whereas the black one is fine.
High Voltages can exist in these sets, never attempt anything while plugged in and
if in doubt do not attempt it yourself and seek the advice of a qualified TV Technician.
There could also be dry solder joints on the panel, usually applies to the power supply as it's mainly these get the hottest.
Here's an example of what dry joints look like.....

It's also worth considering claiming under the warranty for replacement or repair through you dealer if warranty is valid.
Hope this helps

Hi,
Problem is in either power supply or the Y-Sustain board.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.
Often there are fuses on that board - one or more. Check those.
if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
I hope this will help in solving the problem....

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
