I had same problem - no picture, but sound worked - LG 42PC3d - was two months past warranty, but LG agreed to fix it as a warranty call. Service guy was out within a week to replace the Z SUS(?) board. Works fine now. This must be a typical problem, as LG did fix it, even though the warranty had expired. Good luck.

The problem is the "Y-SUS" board. It is inside the set on the left side with several aluminum heat sinks, under the left side brace bar. You can order this board from Union Electronics at www.ued.com .Search for part number: TNPA3243AB-PA
It lists for about 115$

Z-Sustain PCB will cure it.
It is inside the TV, on the Right Hand Side.
www.chsinteractive.co.uk or Google for a replacement.

Doesn't sound like a fuse-related symptom but rather the sign of a failing capacitor in the high voltage supply; when weakening, their characteristics can improve slightly with warmth but it is likely going to get worse.
I don't know your set so can't say if the HV supply is integrated with the main supply or not.
Your model number is incomplete so you will need to add some characters to get the right part.
This company does offer some warranty on their items which are primarily gathered from disassembled sets but check with them:
If you replace the failing board, don't throw the other away, it is a repairable item if you find the right technician.
