I'm pretty sure the convergance chip is out. My

- There is a simple reason you just have a cross on the screen when you try to engage the magic focus---whoever adjusted the Convergence the last time with a remote did not when done reset the sensors--set has at least 6 sensors inside the screen that do the magic focus---After convergence is done you while the convergence grid is still up push a button (on the remote) and the sensors reset--screen will blink with red, green, blue boxes etc for a couple of minutes and if ok --sometimes it will not reset--you are able to get the magic focus to work.

Understand---it is just a gimmic---it only adjusts convergence at about 16 points on the screen.


If you really want to see what you have--remove the entire front plastic grill under the screen in front of the set----two screws on either side in the back and it pulls off---behind it is an inspection plate--remove the plate and look carefully at the front of the circuit boards---towards the left front there is a tiny square switch---it usually has a tiny blue button on the front of it----WITH THE SET ON (BE CAREFUL!) USE SOMETHING NOT METAL---I like to use a pencil (the eraser end) and push gently on the blue button--this will call up the set's internal convergence grid---BE VERY CAREFUL WHEN YOU DO THIS NOT TO GET CLOSE TO ANYTHING WITH YOUR HANDS--LOTS OF HIGH VOLTAGES ARE PRESENT!

TAKE A LOOK AT THE GRID--IF RED AND OR BLUE ARE BADLY SKEWED--IT IS NOT GOING TO ADJUST----TO EXIT JUST PUSH THE SWITCH AGAIN

If the chips are bad (will not adjust or looks 3d) this is a very easy set to replace them on IF YOU KNOW HOW TO SOLDER AND CHECK JUST A FEW THINGS


You can buy a pair of the chips on EBAY for less than 13 dollars plus shipping---sometimes there will be a damaged or bad resistor around them that also needs to be located and replaced---I CAN TELL YOU WHAT AND WHERE TO LOOK FOR THIS.

CHECK IT OUT AND IF YOU WANT INSTRUCTIONS/HELP let me know---I have done hundreds of these sets---if you select my user name here you can look at all my SOLUTIONS here---there are a few recently for the exact same model and brand set you have---WITH THE SAME PROBLEM.
