TV will suddenly change channels, change volume, or go to set up screen by itself
We had a repair man through a major electronics store come to fix our TV because the TV would suddenly change channels, change the volume, or go into the set up screen by itself. We were told that the cable box through our cable company could be sending signals to the "motherboard" of the TV and cause it to do this, and we need to unplug the TV for atleast 2 hours to let it reset itself. Well, it is happening about once a month now, and its getting annoying! Is this possible, or is there something REALLY wrong with the TV?
This was very helpful, and the remote sensor and microprocessor were replaced, but now its doing it again! I think it may be a design flaw of Toshibas overall!This was very helpful, and the remote sensor and microprocessor were replaced, but now its doing it again!

Re:
Yes and this is a common problem! First lets check out the obvious/ when theis fault starts to happen take out the batteries out of the remote control. If the problem stops then you need a new remote. If the proplem persist the remote sensor assy is bad in the tv set. Ive never heard a cable box causeing a motherboard to act up?? Wait arent mother boards in computers?? lol. believe me you need to tell the tv msn to replace the rmote sensor. Now in an extremly rare cases the microprocessor was causing the problem BUT highly unlikly. Good Luck

If the screen is still on but is black, try changing the channel on the set itself back to the channel it was originally on. If you can provide me with the model name of the TV (usually somewhere on the back of the TV), I might be able to find out how to re-set up your remote with it.
Your set requires a qualified service technician to repair it. Sears repairs all major brands, regardless of where you purchased it. There are also many other repair facilities in your local area:
there should be an audio section of your tv
Go through each of your setting s and be sure nothing was changed. goto setup and reset to factory settings. your TV will do something funky and powercycle.
THAT should fix your problem.
if not, is your cable service through your VCR? if so, remove the vcr altogether and connect your cable services directly. All should now be a go.
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
I recently bought a GE universal remote control,
SKU: 24950, that has a control code for the AOC A17W221 TV. I bought mine at Target. You can check online to see if your local store has one before you go there. It's also listed on the GE site under consumer electronics accessories with a price. Don't know if they sell it online, though.
One or more of the front switches are likely leaky. They are less than $3 apiece and I just change them all to save future problems. You might be able to push all of the buttons on the front of the set a few times such as volume up and down and channel up and down and temporarly cure the problem but the switches will likely need to be changed.
Have you checked to see if any of the front panel buttons are depressed and stuck??? this is a big problem these days?? I have also found the infared remote sensor to be bad on some sets that do crazy things all by them selfs.. A funny storry once i had was a customer called me after her mother called some goast finders as her maggy projection set would go on all by itself andf the channels would change and the volume would go up and down all by its self. funny thing I had a set just like thast in the shop at the time with the same problem and I scoped out the output pulse from the infared reciver on the set and that was putting out noise on the data line and caused the set to eratacly do all sorts of weird stuff. get the point?? its a stck button or the remote sensor is bad.
