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

Do not turn this television on! Any electronic that smokes is NOT GOOD! The smoke and accompanying smell is from plastic and solder that is being melted by a short on one of the TVs logic boards. Call a local TV repair man this is not an issue you could fix yourself and will most likely be better off buying a new television. Stay away from off brands like these, spend the few extra bucks on a name brand like Sony, Toshiba, LG, or Samsung and you won't encounter these types of issues.
First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
