I ended up buying a Phillips programmable remote and I got it to work for my comcast, dvd and my olevia tv

Go to on screen audio setup, turn off the internal TV speakers to OFF, set the audio output to 'VARIABLE' (the audio line out signal at the TV RCA JACKS (RED & WHITE) will be controlled by the TV remote), connect a set of RCA cable from the TV AUDIO LINE OUT to the audio input of the wireless speaker transmittere box and set the volume on the wireless to about 1/2 way, you can change this later. Try it and see.

Seems that the company went bankrupt last year and their website (where you would have had to go to download their firmware) is no longer in operation. I think that means you're out of luck, unfortunately :(

I sure wish I had known that before I bought my own Olevia set that needs service now, but at the time I found lots of good reviews of the sets but no news of bankruptcy ever came up.

Sounds like you have a bad signal from the antenna or the cable. Unlike analog TV if the signal level drops below a certain level you loose the picture and sound completely. The fact that digital channels are detected during channel search does not mean they have a good signal. Try moving the antenna about.

you have a bad cap in your power board these can like deivces will be puffed on the top the values will be on the side of the unit

Does the hum go away when you mute or turn down the sound completely? If it does then the issue might be one of the sources connected to it IE: DVD, Cable Box, Satellite receiver..

there should be an "LED setting" in your menu asking whether you want "LED on" or "LED off". there was on mine at least and it seems to have done the trick.

This is an intermittent problem developing on your interface board. The low-signal input is being interupted by a fault in the video processing stages and buffering stages. Get it serviced now before it bacomes a really expensive repair.

If you get no picture on all inputs (TV, DVD, ETC.) then the problem can be in the backlight inverter board or the power supply that supplys the power to the inverter board.

You need to find out if the prolem is in the power amps that drive the speakers are bad or not, Try using Powered PC speakers hooking it up to the Audio line out RCA jacks to see if you get the same problem. If it is OK then the problem is in the power amp sections, it can be bad power amp IC of bad filter capacitors in the power supply that provided power to the power amp circuits.

you require a replacement on/off switch from your local service provider.

you said you are using composite cables..? that means you have some kind of cable box ? if you want to get HD channels you have to use a HD box that is supplied by the cable company.. the HD cable box then has to connect to the tv with component cables (green,blue, red cables) or HDMI cable.. to send the HD signal to the television.

Check that the input is set to cable(catv) Re-auto program.
