Question about Hitachi 53SWX12B 53" Rear Projection Television
When turn TV on, the sound is there for a minute or two, then goes out. It will stay out for hours. To get to work again, a lot of times, I will turn the TV off for a few minutes, then back on. I may have to do this several times until the sound stays on. Once it comes back on, it stays on usually. This is the second time this has occurred. It was the main audio converter that went bad. I believe it is the same thing again. My hunch is, that a solder joint must go bad each time. I do not have a schematic for the TV it seems. I am not sure where this device is located in the TV to determine if that is it, and possibly order a new one. Not sure how hard it is to replace....but I don't want to spend a lot fixing the TV again, because it's not worth it.
I have the same problem with mine, I can also do the ol Fonzy hit it on the side and the sound will come back on. I have re-soldered many bad looking solder joints and I have finally tracked it down to a part # LSK1aF-5v it is located on the board that the main power plugs into at the very back behind a large transformer. The part can be found at parts.o2xygen.com/parts/l/46.html .

I think this will fix the sound problem the part number LKS1aF-5v can be purchased from Digikey.com, they carry it as part# 255-1268-ND, are you ready for this? The part costs a whopping $1.49. If you can solder you can fix this in about 5mins. Thanks, [email protected]
