Thanks for the update im glad the capacitor fixed the issue smps means basically a switched-mode power supply and the ic is just part of it testing that ic would of been the next step in fault finding if needed.

Thanks for the follow-up on the repair.
BTW, did you use the correct type of the replacement cap? It has to be Polystyrene High pulse
withstanding type.

I will always follow up any repair once sorted, that way we all gain something from the repair, thanks for your help with it. I matched all the numbers on the side so hopefully should be ok. Sounds like a pretty sophisticated little thing...

Thank you guys sooooo much, finally got round to testing,searching and buying/replacing the grey capacitor and put board back into tv and to my shock it fired up!!!

Thank God it was the cap as I don't know what a SMPS is!!!

Thanks again for this

So was it the capacitance of this grey cap out of spec?

I have a different LG power board and it occurs to me that my situation is similar to yours. I will create a new thread as my model is different.
