I have the LG HT904TA All in one Home Theatre System plugged in to my LG 50PS60 Plasma TV with a HDMI Cable. All has been working fine for just over 4 yrs now.
Recently, while watching a DVD with surround sound on, suddenly the sound from the speakers stopped. So I rebooted both the TV & Home Theatre & tried playing the DVD again. The sound came on briefly for 1-2 seconds & went silent again.
I tried playing a program on TV & the same result, sound comes on 1-2 seconds & then silence.
So I switched to the sound from TV in built Speakers & sound is fine. I can play TV programs & DVD with sound from the TV speakers without problem.
However, if I switch the sound to the Home Theatre I get sound only for 1-2 secs & then silence (this only if I reboot the Home Theatre first).. if not then silence throughout. The DVD player in the Home Theatre works fine.
I tried with a different HDMI cable, same result.
I opened the cover to look at the 2 boards in there to see if there are any obvious burn marks or bulging caps or leaks. All looks okay. Checked the only fuse I saw next to the power in. It's also okay. I did see some burn marks on 2 wires of the cable going one board to the other. It seems it was touching the heat sink. I checked on the continuity of those 2 wires from end-end. They are okay. Could this have caused some component on either board to short?
Any ideas from anyone?
