Question about Toshiba 32A43 32" TV

1 Answer

Toshiba tv 32a43 changes input by itself

I turn the TV on, and it automatically scrolls through all of the input options. I cannot get it to stay on any of the input modes. The remote control doesn't work either.

I will try to explain this: I first presume there is a physical button on the set for the input options.

I have seen this a lot:
Not the plastic button on the set but the tiny push switch behind it.
These are called momentary switches as only should function when the plastic button is pressed and contacts the momentary switch.

They go bad, and will internally engage without be touched.

The simple way to prove/disprove this is to open the set and get at that switch which usually is soldered into a small circuit board--two pins for the switch and maybe two more tabs for mounting.

If individual switches unsolder and REMOVE THE INPUT SWITCH (the one under the plastic button on the set)

Set should now operate normally and remote should have same feature on it. If it works you do not have to replace anything.

FYI: the reason the remote may not be working is the buttons on the set have PRIORITY over the remote.

Both the remote and the buttons go to the same area inside the set but buttons are #1 in line.

You need the original remote controller to be able to switch input modes.Universal ones usually don't work. If you don't have the original remote and can't find it ever or if it is too expensive you can buy an rf modulator ( very cheap) and connect your dvd player, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me. It placed the connection to channel 4 and other cable channels are still working,

You can buy the RF Modulator from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180299245670

When we try to turn on the tv (toshiba model 32A43) it makes the sound of turning on then off and the screen stays black and a red light by the power button keeps binking


You're either losing high voltage or power supply is not producing the horizontal drive signal, Check for 130v on the collector of the horizontal output transistor, if you're missing your voltage, you have a power supply problem. If voltage is too high you have something open in the power supply such as a low value resistor. If its low, something is shorted in power supply, possibly voltage regulator ic.

Toshiba 32a43 32' picture garbled mess


If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!

Tv will not stay on just tv


Look at the IR emmiter "eye" on your remote thru your Cell phone camera. You can tell if the remote is constantly emitting a signal.

Vertical hold problem


There is a fault in either the input video amp, sync amp, sync separator, or the vertical scan generator areas. Most of the time this type of failure is caused by capacitors in these areas going off spec from age and use.

An experienced TV tech who is familiar with your set should be able to service this for you.

There are a number of things that can cause this.

If you have a compact flourescent lamp in the room, this can cause some models of TV sets to go nuts, or not respond to the remote. These compact flourescent lamps use a frequency band that is close to the data carrier freqency of the remote.

Excellent article about compact flourescent lamps interfering with appliance IR remotes:
http://www.neptunlight.com/files/IR-and-CFLs.pdf


The other thing that can be wrong is there may be a fault in the keypad assembly on the TV set, or a fault condition with the uPC.
