Question about Daewoo DTQ-20U4SC 20" TV

1 Answer

I have a Daewoo 20" model DTQ-20U9SC which is four years old. I have an intermittent problem since yesterday. In the middle of a program on any channel there suddenly appears a big black square in the middle of the screen and perhaps 2" around the perimeter actually shows the program. Is this a problem with the picture tube or could you give me some idea? thank you.

It sounds like you have somehow activated closed captions? have a troll through your user manual and set it to OFF. See if this is the problem?

I have a Daewoo TV # DTQ-20U6SC,the sound is just to low. What can be done about the problem?

You can try using the audio input - RCA jack audio in- to feed an external signal from a DVD and if there is good sound then the output is good and working. If so the preamp is the suspect and there can be issues in the SIF section which might need a signal injection and voltage test to confirm the loss of amplification.

I have Daewoo tv model # DTQ-20U6SC. The sound is just low. I'd like to know what the problem is.

Any sound problem can be confirmed only if the signal is traced and identified so as to confirm the section. You will need an AF- audio frequency - generator to inject and confirm the section where the amplification is low .
Also a check on the pre-amp output and a signal to the INPUT can confirm the output amplfier.
Finally check the speakers, test with a working speaker.
