Question about Zenith IQC50H94W 50" Rear Projection Television
Our TV has a Blue arc on the bottom of the screen that you can see when its in video mode. On regular channels you see blue also. I tried to align the lines up but it won't move. It seems if we leave the TV on for a few days it will work for awhile but then will go away again. My son tried hitting it a few times and it worked for awhile but then the blue came back again.
You need to replace your STK392-150 I.C.'s, Also, check all of the large nearby resistors, make sure none are burned, and remember, you have to check the resistance out of circuit with a meter.
once the resistors are checked, and the convergence I.C.'s replaced, you should be able to converge the picture through the user menu.
