Hitachi 53SWX12B: Sound goes out for a while, then comes back on

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 had this Hitachi 53SWX12B now for about 7 years. The sounds is starting to faze in and out. I was trying to find a solution on the web but not finding one. Please let me know what needs to be replaced and the step by step instructions with pictures if possible to fix. Also need source to buy replacement parts. Thanks!

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,

Hitachi 53SWX12B: Sound goes out for a while, then comes back on


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 .
