in above pics number 1 by the two yellow toped transformers there are some orange items i think these are some type of fuses cant zoom in on the pics to read board part numbers but if these items start with a f number test all of these items 11 i think
better pictures will help us all.
My suggestion would be an old Nikon Coolpix or Canon Powershot, I got my Coolpix for £35 and it takes superb macro photos of PCBs.
But anyway I can see one fuse, it's the white object next to the power connector on the inverter board, what does this measure at? (On 200 ohms.)

Those orange objects are ferrite beads not fuses. They are used to suppress interference generated by some parts of the board. Unlikely to be the fault. If you want, check them all for ohms, they should measure the same as touching probes together.

cheers tom i always wondered what the orange items were so am i rigt in thinking f on a board item fuse fb ferrite bead? and i also have just got a nikon coolpix camera of ebay £15.00 good bargain takes great pics.

On the inverter boards master is part number f2 its ok reads same as touching both probes together 00.3, slave is part number f200 also the same reading.
Are you getting good 24V to the inverters? Test with one end on the fuse (either end) and one end on the case, set meter to 200V DC.

Do you want me to connect all the boards back up to tv, and check. Or just the powerboard.
Connect everything up like the TV would be normally and check. Certain LG TVs (and in general those using the LG.Philips display panels) of this generation have a problem with the inverter driver IC failing. If you have good 24V it could be this IC which has failed.
