If I take the back panel off there is a ceramic 5 fuse right where the power supply comes in the back, it is blown, could that be why there is no pic, I mean could it really be that simple, I tried a lower amp fuse but it did not work,

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. 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/ It will be best to replace the power supply regulator board as card basis.
Fuses can be bought from most of the electronic spare part shops. But, before replacing the fuse, you should check out the cause for the blown off the present fuse, and should rectify it; otherwise, replacing a new fuse at this condition might make problem more complicated.
If you get no sound but the hum, there is a problem on the power supply panel inside this TV set. The only way to repair this set would be to replace the power supply panel. But before you condemn the power supply panel, open the set and disconnect the back-lite inverter supply and make sure that is not loading down the TV sets power supply. You would not see a picture if you disconnected the inverter circuit, but the sound should come on. Good Luck
If that fuse is blown chances are its because the Power supply has developed a short. The power supply will need replacement. You can easially install a power supply yourself just a few screws and couple of wire sockets and the old board pops right out. You can get the power boards from www.tvcircuitboards.com

sound like you might have blown a fuse, or the power supply board is bad. if you can take the back off of the unit and check the fuse it is located right where the power comes into the unit, if that is good look at the power supply board and look at the caps in particular and see if they are bulged out like in the picture below, replace them and you will be all set...
You need the ysus board. This is a very common problem with LG's. If it is coming up with the fuse removed you are essentially removing the short from the power supply so that it can come up and deliver other voltages for sound and all. Check out encompassparts.com if you are going to try to repair this yourself. Thanks
There are two easy fixes you can try. Both require you to take the back panel off. If you are not comfortable doing this, take it to a repair shop.
Place the TV face down on a soft/solid surface.
After you get the back panel off, there are three silver boxes. There are white and black wires leading from the off switch to the top silver box. Take the cover off that box.
Inside is a ceramic fuse. Test that fuse. If it is blown, your local electronics shop can find a replacement.
If not, disconnect the white and black wires from the PC board. Remove the 6 screws holding it in place.
Look for scorch marks under the board.
Cut a thick piece of plastic and tape id down over the scorch marks.
Re-attach the board with the six screws and re-connect the black and white wires.
Turn the power switch to the OFF position and plug in the TV.
Turn on the power switch while WATCHING the board you just removed.
If you hear a sizzle, turn off the switch and get a thicker piece of plasic.
If not, the TV should come back on.
Re-assemble the silver box and put the back on.
You have a short in the power supply. Look at the regulator and or rectifier diodes. These are all on th primary side of the SMPS (switched mode power supply) the secondary side if shorted shouldn't cause a blown fuse at all.
