TV was working, it then stopped and a arcing sound could be heard. Power stayed on buy I isolated it straight away. Check back of unit and tried to restart after waiting about ten minutes. Blue arc was seen from right (of the three) "module" at the base of the screen.
I have never had an issue with the set in the past.
Is it repairable or is it dead?

Re: LG RP TV wents fizz, now no picture or sound
The flyback transformer or the "spitter" has a problem and should be replaced. Figure on about $100 for the part(s) and the local labor charge as the cost. Call around. This is a simple diagnosis as the insulation has broken down in the part.

Your unit has some sort
of PSU fault, or a problem that is shutting down the Power Supply
Unit, PSU. This happens so that no further damage, and possible fire will
occur. The sound is it starting up, shutting down, over and over. You need to take the unit to a reputable service
centre/man and ask for a firm "Quote" for the work to be done.
Sounds like youre lamp might gave blown pull it out and see if it is shattered check your owners manual to see where it is located most of these are on the right side as you stand in front of the tv but some are also in the back.
If this is similar to the d52w20 then I almost garantee you need to replace a capacitor. You can check to make sure that's what you need by unplugging the tv, taking off the back cover and feeling the top of 3 capacitors. On my d52w20, CP150 (rated at 2200uf 16V) was blown and the top was bulged out. You should also check CP120 and CP114 to see if either are blown. I don't have a clear picture of where it's located, but I have a picture of what you should see after you take off the back cover.
In the middle of the picture you see an aluminum heatsink in the shape of a 'C' with the opening facing away from you. That is where CP150 is located. CP120 and CP114 should be located nearby, but if you can feel a bulge on any of the tops of those 3 capacitors replacing them should fix your problem. Replace the existing capacitors with a higher voltage rating of either 25v or 35v.
"4 capacitors on the power/deflection board. CP110 220uf 200v. CP120 220uf 35 Volts. CP114 220uf 35 volts. CP150 2200 16 volt. also check entire delfection board for cold solder especially around flyback. bad connections here can cause problems like some of the fp fuses blowing and cutting off convergence supply"
