Cable Guy messed up Bose 18 sound

Check the remote control for its infrared emission. Check it with fresh batteries. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience.

I think your problem is with the scart socket . It most likely to be a dry joint on the pin where the sound goes in to the tv. you have to take back cover off the tv and turn the chassis over to do the dry joints if you can do it yourself otherwise get an engineer to do it. Good luck.

You need to turn on the cable box again. Make sure to select the right source again for your tv.

Hello
You just check if your remote control hanset emits infrared light. There is an infrared light emitting diode, an LED [Light Emitting Diode], in front of your remote control hanset, from which that rays goes to the infrared sensor inside your TV, which in turn receives it and processes it. You can check its emission. You may have a cellphone with camera option. Set it to camera positon and face your remote controls' LED towards its lens, at a distance of say 1 feet or so, just press all keys one by one and see whether there is light comes from it or not. Your cellphone camera will sense it and you can see its image on its screen. If not, your remote handset is not working. Check its battery contacts for any dirt or rust, that prevents proper battery contacts. If it is Ok, just open it, it is snap fitted and you can open it. Check whether there is any loose solderings on the leg soldering of the above said LED, or a crystal used inside it. If all are ok, you have to replace the remote handset. OK.

1. Step 1 Take 2 to 3 people and carry the rear projection TV into your house. Once you have the big box inside, utilize the casters on the bottom to slide the television on the hard floor into the room you want to use.
   
2. Step 2 Find the rear speakers-for optimum sound you will want to attach these speakers at ear level.
   
3. Step 3 Determine which kind of cable you will need. There are 3 types: coaxial, S video, audio/video cable.
   
4. Step 4 Select the type of cable you need-you will have to find out what type of cable has been installed in your home--standard coaxial cable or 300-ohm twin lead cable.
   
5. Step 5 Decide if you need a cable box to continue the connection process. Some cable companies send out scrambled signals so you are forced into renting their descrambler.
   
6. Step 6 Set cable to "On" in the channel set-up menu.
   
7. Step 7 Program your remote to the Toshiba rear projection TV-this will allow you to control the on/off button and volume control.
   

cable signal is weak. Tech. must check house wiring.

your TV and, your cable box both "see" a series of invisible (infared) flashes of light like morse code these flases tell them what to do.one answer is to: buy a universal remote so that you can program a button for each device then when you want to control the cable box just push the "cable" button and, then volume etc. to turn your tv off push "tv" then "off" the service man was right but he should have explained this to you
also your cable remote may be programable to work with your tv like a universal remote check with your cable co.

All you need is a cheap adapter ...you can find at radio sgack...just tell them what you told me and they will fix you up!
this should fix your problem

I just realized that there is no usb port on this tv. Called tech support at vizio since I'm still under warranty. They're sending a new remote. I know it's not the remote because neither the verizon nor the vizio remote works, although the vizio remote will intermittently work if I'm one foot away from the sensor on the tv and holding the remote on a downward angle. Tech support says they will send a new remote to rule that out before they send a tech over. I'll check the posts to see if you find a solution when I finally get the tech guy out here. If not, I'll let you know what he does.

Good luck.

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.
