No sound. Connected to only a HD cable box via HDMI cable and red/yellow/white audio cables. We purchased the set used and I have no idea how old it is.
Right now I am having a signal resent from the cable company. They said the reset process could tak eup to 45 minutes. I removed the audio cables and have only the hdmi cable connecting the tv to the cable box.
I will keep you posted.
Thank you for your help.
I did the reboot you told me to do prior to contacting the cable company. After I rebooted by unplugging the power cable from the back of the cable box, I would not ever get the power indicator light to remain steady. My problem is most likely with the cable box and not the television. We shall see.......
OK. Service and power have been restored to the cable box and the tv is now picking up the signal. But, still no sound. So I hooked up a DVD player using the s-video connection and the yellow/red/white audio cable to the back of the tv, selected s-cable and got the dvd video to show up, but NO SOUND! Next suggestion?
Okay, this is rare. One of two things would cause THIS. Either the TV's EEPROM (processor) locked up and needs to be rebooted, or the Mainboard's Audio processing in the TV is faulty.
Try a hard reboot of the TV. Disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. Plug it back in and power it on. If you still have the same problem, then you need a new Mainboard. This is the board that houses all of the AV Inputs on the back of the TV, as well as processes sound, and the amplifier that drives the internal speakers.
In this case you can purchase the Mainboard for your set at the link below and replace it yourself in about 20 minutes with nothing more than a screwdriver:
You rock! This worked. Thanks!
