I have a goodmans LD3201 TV and the display in the corner of the tv is constantly on mono. I have tried altering the settings for sound on the menu but there does not appear to be an option for changing sound to nicam although there is a box next to the mono one which is unlit. This is driving me scatty as I have now brought a home cinema set which also will not work on this TV but will work with others in the house straight away. Please can anyone help me as I have trauled the internet with no luck looking for a clue!! Thanks

SOURCE: Green box keeps popping up in upper right corner

You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

SOURCE: Small black box in upper left corner of Sony TV - need to remove

I had a similar problem on my Toshiba Regza but trying my fix couldn't hurt. I use a satellite dish for TV (if you do the same this might work)... I turned off my receiver, took the programming card out, cleaned it with my shirt (especially the part that looks like a computer chip), put it back in the receiver, turned it back on and when everything reinitialized the black rectangle was gone.

Hope this helps.

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.

Sharp Aquos LC-32D44U stuck in ""Mono"

I dont know if this will work for you, but its worth a try. I had the same problem.

1. I changed to a station that was having the problem (an analog station with MONO displayed on the screen).
2. I unplugged the TV for about 15-20 minutes. (I was thinking maybe something needed to refresh, so thats why i unplugged the tv.)
3. I plugged the tv back in and voila. The station showed up as MONO then immediately swtiched to STEREO.

After that, i was able to use the AUDIO feature on the remote to actually change from MONO to SAP, etc.

Ive had my Sharp for about 5 months now, and thats the first time its happend to me. Luckily, i solved the problem...this time.

Hope it helps.

Stereo/Mono Fluctuation Screen Display Problem

I had the same problem.

All I did was unplug the standard cable wire from my tv and used RCA cables to connect my TV to my digital cable box the the Input 1 jack in the back. It also increased the video quality.

Volumne on Akai LCT3285TA

Often a signal might experience a super-quick "drop" in signal strength, and the display is automatically adjusting the now weaker audio signal to "mono" (temporary, as for best quality). But the dropout is usually so brief you will then see the "stronger" signal restored [full strength], and now the audio is "stereo".

It's like a "bump" or "disturbance" that occasionally affects the cable/satellite/OTA (antennae) signal being fed into the TV, and your display's attempts to compensate for the weaker signal [going to mono, then back to stereo once back to full strength].
Connecting it to your cable directly (bypassing the box) or an antenna would give you a true over-the-air signal, which would be proper MTS and would not give you any more pop ups.
