Question about Sony KP-53S70 53" Rear Projection Television
I had the TV on and it seems the red color started arcing up in the middle and down on the left and right. I wasn't changing channels or anything. Any way of adjusting it? I know how to get the front panel off already if that helps you when you explain your diagnosis.
How do i get the colour menu to display on the screen?

I have seen this before check your TV to see if it uses the STK-392-110 3 channel convergence module. If it does you may have to replace them (there are two of them). You may read something about replacing them with the STK392-150s but don't do it since the replacement requires the changing of the bias resistors, and you need to know ecactly what you are doing. You will need to desolder the the old modules and solder in the new ones (new 110s not 150s). I would advise you to get a schematic and check the voltages on the chips before changing them just to make sure they are bad.
