Question about Labtec LCS 1040 Computer Speakers
My Sony MFM-HT75W 17in Multifunction Display shuts off 3 seconds after being switched on. Green power button stays lit but the screen goes blank. It doesn't matter what the input is: TV, PC, video
Picture not clear with white colour

Hi, I was able to fix my set by changing only three out of the six capacitors between the heat sinks opposite the plug on the board. I noticed under a microscope the caps looked a little puffy, but not much, and I checked them with a capacitance meter, but they were in tolerance, but decided to change the three closes to the edge of the board with a 1000uf, 50v, 1000uf 25v and 1000uf, 50v with the one that is 25v going in the middle, I didn't have another 1000uf,50v for the middle one. (sometimes you gotta use what you got to get what you want) So I powered my set up and it stays on . I hope this helps. I may go back and replace all six with 1000uf, 50v, but the space in there is limited and those are some large caps. I will wait until the set acts up again before i do that. I am satisfied with it for now. Again I hope this will help with what you've got going on with yours.
