While dusting our 3 yo Akai TV there was a spark as I rubbed over the lower TV control panel. The volume control is now stuck on high. The TV screen constantly shows the volume setting at 100%. The channel changer for TV won't work for changing channels, volume or mute. We are using our cable box and VCR to change channels. I put tape over the front TV speakers so that the sound could be muted somewhat. Any suggestions as to what to do? I am afraid that a service call will cost more than the TV is worth.

the volume control is increasing randomly on it's own because the volume button on
the TV is partially stuck in, that is why its coming up occasionally.
This same thing may also happen to the remote control of the TV.
Use your find to rub the buttons on the buttons on the TV, especially the
volume control button. Do same on the remote and most definitely
problem should be solved.
Please give me a feedback if solution does not work for you.
It seems to me that one of your guns behind the lower half or your rear projection HD TV . Is either out of align but more than likely one of those projection guns are Blown. Take the projection panel of carefuly. It should snap off and on as does my Sony. There is a few screws which will have to be removed remove them. You should now have the projection glass panel completely off be careful not to scratch it place it in a safe place. Turn the TV GUNS BACK ON TO SEE WHICH COLOR IS BLOWN. Be very careful get a soft feather duster and remove all dust and or Debris it can sometimes get very dusty based on the heating system and Ventillation in your home. After you find the projection gun and model # call the Manufactuer for the replacement cost check with Ebay before ordering you may be able to find a better price than what the Manufactuer offers. I hope and Pray this will help you with your issue. If you can not remove the projector get some one with more mechanical experience to help You! Nothing beats a failure but a try!
Wow, You are asking for a complete disasemmbly. If this is necessary, you have to remove any screws you can find that are connected to the front panel. Usually they are in the top of the set ( you'll find them after removing the mirror panel and mirror ). I wouldn't remove any tubes as the tube convergence would have to be all reset and that would require a cross hair generator. I do hope this has helped in some way, but all I can do is send you my best wishes as I certainaly don't suggest disassembly if there is any other way. Good luck
Something like this Id have someone who knows there way around electronics, a qualified tech or someone you trust really well :-) Does the crackling affect the TV picture at all ? My first guess would be dust and or dampness on the audio components. Sometimes this can conduct electricity across small pc chips and reak all sorts of havoc. I had an old Tomas electric organ once, and it actually caught fire because two speaker wires were rubbing together and eventually wore thru the insulation and shorted out, but it was also making alot of crackling and static noises. Try raising and lowering the volume low to high and high to low and see if the crackling noises gets worse. Some audio amplifiers put out quite a bit of power, so I wouldnt trust leaving the TV on without a fire extinguisher handy.
