Re: LG55UB850V no picture or audio - flashing LED's help please?
I think the problem we have is with the angle of the camera in some of the photos. It can make things look different to how they look to the naked eye.
Regarding the coil filter 2R2, again the camera photo might look like it has some sort of heat damage, but it looks completely normal to the naked eye, and identical looking to the other 2R2 coil filters on the board. My meter doesn't test inductance, however all 3 of the 2R2 coil filters read 1.5ohms when on the resistance setting.
I have checked the micro switches and they are not stuck down. When pressing or pressing an holding for 2 seconds, they briefly stop the buzzing and the LD goes out, then the LD comes back on and after a second or so the 2 second buzzing cycle begins again.
I see there are quite a number of T-Con boards for sale second hand which have the correct part number for my tv, so I think for the relatively small outlay it may be worth buying one and swapping it out to see what if any difference it makes. If no different then I can hopefully sell it on again!
There still aren't any second hand main boards for sale anywhere that I can find - lots of hits on google search but they all show 'out of stock' of used second hand boards.
