Help - I have a Tecwood TV 40AO2USB that does not power ON. It has power and after flashing it little blue led for 10-12 times it stays on (blue) and no matter what I do I cannot get it to do anything else, other than power OFF. Can someone guide me what checks to do; I have a Fluke Meter and I am competent in using it, as well as identify key board components. I have the cover off and have checked for the obvious (loose cables, blown capacitors etc.). It does not help that I do not have User or Service Manual for this TV!
