Question about Daewoo DTQ-20U4SC 20" TV
Unable to program the unit to accept additional channels. The TV shows one channel only. The same channel is seen on all stations from channel 7 upwards. From ch2 to ch6 I get only the raster. It goes through the programming sequence, but at the end only the same channel is seen. I have adjusted those parameters that were out of specification in the service mode adjustments. Still no change. I have tried to add the channels one by one, but no success. Every other aspects of the set appears to be working fine except the auto channeling.
Grateful your assistance.
First ensure that you are performing the auto channelling procedure correctly.
If you are sure you have done everything in the proper way, and channel tuning still does not work, than that means that the tuning board inside your TV is faulty, and is not storing channels in memory, therefore should be replaced.
