Question about Polaroid TLA-04011C 40 in. LCD TV
Yes you are correct you have a floating return ground on the main system control board, check all ground connections on the microprocess itself, you might take a light torch and try heating the micro area of the sys control board. There is no reset on this model its done by the microprocessor, but there is a reset lead on the micro which should read high while operating normally, Logic probe this pin while turning on the unit if it continues to stay hi even when turning off the unit then replace the Main system control.
