Re: HITACHI 55HDS69 power, sound but no picture

Hi everybody! well i found a curious problem i have to buy another psu but i have the same issue, no Va & Vs, but this time i decide to explore another solution, i reflow the "logic buhin Board" and i have 5v in the grey wires, then i suppose something happening, but no...then i check the buffer board for something wrong, and i found 4 polyester cap burned, 2G103K i google this cap, and i found it´s a 400v polyester film capacitor 10x100 10% tolerance. so i got to buy some and test again, also i reflow the buffer chips,...
