On your remote control (with tv off) 1. press Display, channel 5, Volume Up and then Power this brings up the service mode (you will see some green text on your screen) 2. Press channel 2 to scroll through options until you see "Micro" in the upper left of your screen (channel 2 cycles up through the options, channel 5 cycles down) 3. Press channel 1 to scroll through suboptions until you see "DIOF" appear under "Micro" (channel 1 cycles up through the suboptions, channel 4 cycles down) 4. Press channel six until the default value (12:60) changes to 12:40 (channel 3 increases the value, channel 6 decreases the value) 5. Once the value has been changed to 12:40, press Muting and you should see red text in the upper right hand corner that says "Write" 6. Simply turn the power off and back on for the change to take effect. Your volume problems should now be fixed.
I cannot be sure of the exact model but... Press and hold the TV's volume up and volume down buttons simultaneously. On many older televisions, this opens the device menu without the use of a remote. Otherwise, use the menu button, which you can navigate in a similar fashion.
Also, somewhere should be an input button. Press it multiple times times to switch between various inputs (the input must match whatever input you are using). Usually after these menus are opened you can use vol up vol down to change things.
Controlling the TV power and volume is probably all you'll be able to do with that control. The Comcast remotes are meant to be used with their converter boxes, and normally people want to change channels on the box while the TV stays on the box output channel (usually 3, sometimes 4). The remote's channel up and down buttons and number keypad only send out the codes recognized by the converter box. You'll need to fall back to the TV remote if you want to control more than power and volume.
the problem is with the control panel of your tv...make sure your remote doesnt have any part in this...just remove and the batteries and check if the channels still are changing.....see if the onboard switch for channel changing is stuck ?..if stuck u can use homemade tools to pull it back......if your tv is within your gurantee period...just giv a call to customer care....if not u can take it to a local repair shop...there is nothin that u can urself do to make it right ...sorry....for further info contact at
due to the long time the buttons were not used, they tend to get stuck and this causes channels eighter to stay in one station or continou scanning. it could be resolved by spraying WD40 on the buttons and press it many times then dry it before operating the unit.
I have the same problem, except that it would turn on by itself and then start changing channels. I had a can of compressed air and sprayed the button areas to see if there were sticking. It worked for a coupe of days, then started happening again. So I searched the web and found a response to a question someone else posted and the ensuing reply "most likely you have one of 2 things going on one is the foam between the buttons and the switches or you may have a switch getting leaky and would need replaced" Looks like I may have to taking the cover off and find some type of electronic cleaner, or replace the buttons. I find it odd that I got hits for the same issue with the same model. hhhhmmmmm?
