LG LG 42LH3000 PSU EAX55357705/4 Help with C402 identification?

[cheeky2]

I have a LG 42LH3000 psu EAX55357705/4 that the C402 capacitor has broken down on the inverter side. The C401 is a 22pf 6KV however the C402 looks slightly larger hence I need to ensure I get the correct value for it.
So if anyone has the psu sitting around that they can tell me the value of it then it would be great so that I can order one to replace the faulty unit.
See attached picture this is from a picture found for the psu. Mine pictures are on another PC which I will upload tomorrow.
I have marked the C402 in the picture with red square so that it can be identified quickly on the PSU.
Just managed to find the information online from a picture which is a 54j 54pf 6KV, reading up it looks difficult to find however can get a replacement psu for just over £4 delivered!

Here are the pictures of the boards with failed C402 and a similar board used with the same model of the TV.
I have now ordered a PSU for it £4 delivered and caps of 56pf 6KV for repairing the existing psu, I couldn't find anyone with the 54pf 6KV. I contemplated putting two 27pf 6KV paralled but decided against that, as the holes for the components would have to be enlarged. The 2pf difference will unlikely affect the operation of the inverter part of the psu.

I have 42LH40, the board looks identical and yes, that cap it's 54pF.
Since you ordered new board, why not use it? There could be more problems.

I would try it with just the one 27pf/6kv cap It is not that critical for a value, Then if everything works, either add the second cap or get the correct one.
