Question about Toshiba 32A33 32" TV

1 Answer

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?

Re: TV will suddenly change channels, change volume, or...

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

TV turns on & off by itself. Channels also change by themselves.

Make sure your remote is totally away from the set.
Make sure the buttons on the set are not sticky
If both of those are ok, it's your E-Prom in the set. RCA's are notorious for this, not a major repair, maybe $75-100. The 8 leg e-rom is only about $6.00

Volume stuck maxed out

the intrenal switch that controls the volume up is shorted. you need to have it replaced. the short of the switch doesn't allow any other buttons on the set to work because the micro is recieving the volume up command. it's as if there is an invisible finger pushing the volume up button. the switch is a tachtile switch which is very inexpencive to repair about $50.00 total. if you want to do the repair yourself be aware there are voltages that remain in the set that can be harmful. 50% of the time the cause of these switches shorting is improper screen cleaning. some people spray glass cleaner directly on the screen, this is bad. the cleaner drips into the set and lands on the PC board where the buttons are housed. but I've seen the other 50% also which is hummidity, dust(not anyones fault this just happens), and simple switch failure. so becareful repairing it your self

Keeps changing channels/volume by itself

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.

Why shouldn't it be worth fixing? It's only 4 years old, my own TV is 15yo, I fixed it twice but it's still kick'n! You have a problem in the power supply, do you have electronic's know how? And test equipment? Soldering equipment? If so we could walk you through it, If not A repair man should only cost 80 to 100 to fix it.

Only receiving Channels 50 and above; no lower channels

It could be anything from corrupted data in the EEPROM (a memory IC that stores all the channel information and picture settings) which is usually caused by bad ground solder connections inside the tuner itself which is built into the main circuit board and would have to be repaired, not replaced or components inside the tuner section of the main PCB. With that being said - if you have to get a technican to come to the house and repair the set then it would probably be best to buy a new HDTV set. If you can take it to a repair shop capable of fixing the tuner, it could cost close to $200 to repair is my guess, and may work OK for another year or two before the picture tube finally wears out.

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?

TV problem

Any chance for a screenshot? The three colors are the three scanning electron guns firing on the screen instead of painting a picture, and yes, this is major repair. Not sure if it will be worth the repair cost, but you could get an estimate if you like the picture the set produces, when functional. Good luck!

TV changes channels itself

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.
