I'll give it a go (when I work out what and where these leads are)  |

| Swap leads on the screen/focus block. In other words follow the blue screen/focus wires and swap them with the red or green screen/focus wire and put the red or green wires where the blue came from. I'v had bad focus/screen blocks before. | |

| Answer to that is Nope. Changed the IC over and is still the same. Blue is blurry and doesnt seemed to be repairable with the Focus/Saturation/Lens dials.  It probably is, but it eliminates the Perfect focus, and is still very slightly off (noticabley). Red and Green I've messed a little with and they are spot on, blue wont follow suit for some reason. It seems wider or bulkier. I'll try to get a picture to show you how I mean. Anything else I should check? Perhaps another resister somewhere? |

| I'm really not happy with the way the blue is showing on the screen at the moment. I have a couple more STK392-040's here. Could it improve it if I change the blue one over perhaps? |

| I wouldn't sweat it. If you cant get it you can still adjust it in the service menu. You can try temporarily turning blue screen up to see if that helps. | |

| Picture seems a lot better, but the blue perfect focus doesnt finish when trying to save and when trying to use it, it reports no sensor data. Gonna try to sort convergence manually now. |

| Sounds like the fluid is fine. | |

| In B&W, the picture is awesome! Apart from a couple of convergence issues (some red and blue in places). Note to self or others - GREAT TIP! if your having trouble converging, go black and white, any slight green, blue or red still showing, thats the area's to converge!! Screen 'bing'... (Typo?) being to high or too low. How do you mean? I've made some really minor adjustments using the knobs and have the blue quite clear now, but perfect focus has gone tits up again (gonna try to re-save it now). All the fiddling for the last hour or so has made great improvements (hoping the fluid still good!!) |

| What happens when you play with the focus? Now don't shit yourself. You may have contaminated fluid. But you say it looks ok or better on the other side? Screen bing too low or too high can also cause a blur effect also. Check you gray scale. That means bring up the menu and turn the color all the way down. You should have a good black and white picture. If there's a r/g/b hue that means a color is to high or one's too low. | |

| Took the screen off (easier than I thought). Found a dead fly on the green lens, nice, got rid of it. Adjusted the blue to the best I could get it, but still have a slight blue ghosting effect on one side of the screen. Leftside seems better. Could this be a faulty STK IC again and I need to change the blue STK? I'm gonna have another fiddle with the convergence on the righthand side to see if I can get better results. Does the convergence settings need to be completely symetrical? I cant seem to find the correct measurements for the lines in the Service manual for a 42" version and have a bowing effect when straight move across the screen. |
