I have a Toshiba 32a33 TV, I have tried to program channels into the TV but it doesn't work. I tried to do it both manually and using the automatic channel tuner but it doesn't work. What should I do? It can't seem to find any working channels on either TV or cable. All it has is the white screen no sound.

Either the tuner or the video IF stage circuit of your TV is faulty. Tuner has no repair, can be replaced as a unit. If the fault is with video IF stage, it can be repaired. But, both the work is skilled one. You must have through knowledge in electronics, and work experience to do this work.

SOURCE: TV's tuner will not recieve all channels

Since you are not using a set top box, you will probably only get channels up into the 70's, if available in your town, as most channels above this are digital, which analog cannot convert.  As for the digital tuner, I have the same problen.  It will not pick up any digital channels.  Because of this, I have had to get a digital box(why in the hell should I have a digital tuner?) to recieve digital channels.  I have the same tv you have, except a standard def.  If you ever find out why your digital tuner won't work, I'd love to know myself.  good luck, hope this helps.

You'll most likely need a Sansui remote made to work with your specific model TV. I have similar problems with my Toshiba TV. Check eBay.

There is a button under the bottom edge of the screen (with the controls) that has the options "Normal" and "CATV" - press this and it should solve your problem.

My Serial number is 94590994 and I cant tell what universal remote I need. TV is Stuck on channel 2

Do yourself a favor and save time, money and aggravation and locate an original remote, universals if they will program will be missing key features the original had.

If you insist on a Universal, use your computer and Google with the model number search for remote. that should give you a few hundred different remotes that might work.

Hi,

All you need to do now is to buy a new tact switch and replace all of them to resolve the issue. I'm not sure how it looks like the one installed in your unit but you may click this link to buy online. Watch the video below for more info regarding soldering and desoldering the parts on the board.

Toshiba 32a33. I'll be watching tv and the volume bar shows goes down to 0 (no sound) when it is in this mode the remote control will not work on the volume, you can get up and manually up the volume...

1st check to see if your remote volume down button is stuck. 2nd do you have wireless internet (router) or any other wireless devices phones,ceiling fans, another Toshiba remote, if so try unplugging them (or remove the batteries if it's a remote) while it's changing the volume one at a time. If a different device makes it stop try changing the channel on it. Also make sure the t.v doesn't have a mind of its own and remove the batteries out of the t.v remote, let it ride for a couple days if it happens without the remote being in play then you know your t.v is acting strange, if it stops then starts back up when you start using the remote again then you know your dealing with a remote issue. Sometimes Freq.'s merge causing remotes/wireless devices to conflict with each other.

Universal remote works for basics but won't change input

Rich,

good day , what button can you see infront of your TV screen?

Not familiar with this model but if you'll manage to locate a button marked as "TV/AV" or "AV" press this button until it the display switch to A/V mode (audio/video). Or if this is a really old model, from Tuner mode or channel model. set the channel station to 1 then press the " - channel " button and see if it will change from tuner mode to A/V mode

cheers,
mark
