Daewoo TV - "HEAT RUN" on screen.
 

We have a DTQ-20V1FC that has a white screen with "HEAT RUN" displayed
on the screen. If I go into factory service mode and reset to factory
adjustments, it disappears but when I unplug the set from AC, it then
reappears until I go into service mode again and do reset. Have anyone
had any success with this set for this problem? Should I change the
EEPROM?
