Question about Toshiba 57H82 57" Rear Projection Television
Hi, Acquired a 57h82, that has a convergence issue. The picture is ghosted in red and the red convergence cannot be adjusted left to right. Up and down is ok. I replaced both of the convergence chips, but it made no difference. I assume as I did the chip replacement and the issue is still exactly the same, I did it ok. Does anyone have any other ideas... I have heard that some resistors on the board can be a problem, and should be replaced, but which ones and how do I check them? Thanks
There are probably eight to ten resistors sitting behind the heat sincs the Chips mount on. You will need an Ohm Meter the easiest way to check them is just compare them with one another, you will see a pattern then you will see one that is really high or open (infinity) that is the one to change check the coor code on it to be sure you replace it with the right size
