i have recently replaced my convergence chips (1 day ago) and the red was now out of alignment.So we took the panel back out and cleaned up the solders more,and put it back togeher,(hooked all the wire clips back up) and after we did that we turned it on and all we seen was a green led light flashing on the board and it blinked for about 10 seconds and then the tv turned itself off,we tried it a couple of times and it kept happening.Can you please help me with this problem,i would greatly appreciate it? Thank you jonathan concerned hitachi owner
First thing to do is check your work! In other words check again all the connections and solder pads for exsessive solder and or solder bridges. next would be to check every single plug and plug socket connection for the plug or socket not seating down all the way flush to each other. Check all of the fuse in the differant power supplies. If none of this works, you will need a manual or a service schematic to trace out the circuit fault. I'm not sure if this problem is a man made one, and those can be a dog sometimes to find, or maybe the IC's you used are bad or not the original manufacturers parts. Good Luck, and let us know how you made out.
