Hi,
Just found your post from last September. Did you ever sort out your problem? I have almost the same model, mine being the 28", (that's probably the two imported and sold by Powerhouse!), and my set is now doing the same:
My JVC AV-28X35HKE television has just started to give a problem. It will mostly turn on at the first attempt of the day and all will be well, but thereafter either won't turn on or when it is on, the volume/channel controls do not operate. I have also noted the following:
- Pushbuttons on the set do nothing either
- Switching off at the main button and even unplugging for several minutes does not help
- The stand by button remains lit (red). If I can turn the set on, it goes green
- I have other remotes in use with the set, and they do not work with it either
- Just in case one of the above remotes has a button stuck, I have even removed them from the room to establish if they are affecting the set
- I have even disconnected the scarts to no avail
The above is copied from my posting currently near the top of the forum. It may be too late for you but let's see......
