This set uses Hercules IC TDA12079H1/N1EBF. Starting +5v & st by +3.3v, +1.8v are ok previously green led & simultaneously relay in power supply were switching on/off.There is no h-out. As per my knowledge set goes in st by mode after detection off any error. In this case, no st by is possible even on remote!
Later I replaced this IC, but now no green led, no h- drive & nothing else happens! Set is still dead!! Only this IC becomes slightly warm.
All above mentioned voltages are still ok! So also +B 135V.
Please somebody provide me a solution.
