My Aucma black and white tv only has sound but no picture, what's the problem?

my TV has a half black & half white screen & half of the TV is showing the picture including the normal sound,what can I Do,?

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

tried with resetting doesn't work?totally black screen or has a white screen display?

Depends on what is causing it...

Vertical bands of faint black are generally caused by filtering capacitors and can be found in the power supply or the 5 volt supply or even the Video processing circuit...it is not an easy task to identify the source of Video hum bars.....we also call them Jailbars.

Another problem seen is faint black lines caused by the TV set being in 4:3 mode all the time....right at the edge of where the picture ends and the black pillars begin, we see a faint black line that never goes away and is normally seen with a full screen....

That is actually image retention, but it's caused by the crystals that create the picture becoming polarized or ionized over a very long period of time....and it's not easy to DE-Polarize them !

But there are some theories out on how to do that....
Certain people suggest running the TV overnight with an ALL-WHITE picture and some suggest an ALL BLACK PICTURE...and some suggest alternating between both !!

Now, a black picture is easy to make, you just deactivate the Video Mute (blue screen) and set it to an unused Video INPUT overnight....

About the only way to make a white screen is to use the USB port for pictures and take a very bright outdoor shot of a piece of white paper that hopefully is out of focus too....That would create an all-white picture that you can plug into your TV set overnight....

Now if you decide to try this, deactivate any displays on your TV set...all you do is press the display button until the Video and/or USB input numbers disappear....

Next day , set it back to normal TV and see if it's gone or if it's REDUCED....try it again if needed, or try the exact opposite if you see NO RESULTS....

tried to look at the darkened room if their is a white screen, it could be the t-con board. if totally black screen, it could be the inverter board was busted or the screen back light itself.

This might require attention by a qualified service technician.

This seems related to the TUNER and the IF section as the sound- audio and picture- Y signal does not process with the correct alignment.

It sounds like you may have connected the dvd/video combo to the wrong spot on the television. The yellow wire cannot be placed into the green hole. You'll get a picture but it will be in black and white. You can only connect these yellow, red, and white composite wires to a component input spot on this television in order to get a color picture.

This tv have a colors wheel design in it.The tv make loud grinding motor noises or pictures flashes or freeze and pictures turn in black&white with sound.The tv colors wheel it is dying or worn out already.Don't tries to change the tv colors wheel ur self.If u don't any mechanical skills,because the colors wheel it sit way back of the tv,must take out many mechanical parts before even can come to the tv colors wheel itself to replace it.Best to hire a tv tech. to change the colors wheel,so no problems for tv funstions for later or damages more parts on the tv set,if u install the new colors wheel in the tv wrong way.

is there still a picture?
