| I took the board out again and found the new resistors to be discolored as though they had been heated. Can any tell me what the correct value of these resistors are RZ123 and RZ124, they are grey in color and have the following color bands. Orange, White, Gold, Gold and finally White. I think the replacement resistors couldn't handle the heat has anyone any got any good internet sites to get repalcement resistors? Also I know they are 3.9 ohm but what wattage and tolerance? Has anyone replaced these pars and if so where did you get the replacements. |

| The line on a blue screen looks black and runs vertical in the centre of the screen. When a TV Channel is selected the line turns into red green and blue and looks like the screen has been drawn on using whiteboard markers/pens. There is also a green V-shape to the left of the line. Could it be the replacement 3.9 ohm resitors or ICs? There is nothing on the rear of the screen, lens or mirror so I am really stuck now has anyone heard of this before or got any ideas on what is causing this? |

| I replaced the resistors and the convergence is fine now - thanks for the help. But I now have a line right down the middle of the screen anyone got an ideas o this one? |

| I founf ther pico fuses thanks - they a green in color, they both checked good. I did find two 3.9 Ohm resistors bad RZ142 and RZ143 any ideas where I can get suitable replacements? Thanks for the help so far. |

| Thanks for the info - I have found the 3.9 ohm resistors but I am unable to locate the pico fuses could you explain what they look like? |

| Also check the 3.5 amp pico fuses under the heat sinks. |
