I recently moved and apparently after I moved, I'm guessing that the projector moved and it looks blurry and double picture, how cam I fix this?


you might have a bad connection going to the convergence move , a connector might have came off. Or the cable that that you are using going to the set, is defective and needs to be replaced.

Sounds like a loose solder connection on the Convergence board or the convergence power board. If you are savvy and electrically safe, tap on the boards with an insulated screwdriver to see which has the loose connection, and you can resolder to fix. Repair from a service center = $150-300

replace the convergence ICs STK392-120 you will need both of them also check the 6.8 ohm resistors right next to the ICs as often 1 or 2 of them burn open. You should be able to notice the discoloration in the center of the resistors.

Are your colors out of convergence also? If so this is a classic symptom of bad Convergence ICs.

Hour glass as picture


It is possible that your television needs to be degaussed. Gaussing occurs in televisions that have magnets, (usually speakers) placed to close to the unit. A degaussing coil can be purchased at a good electronic supply store. Simply follow the instructions that come with it. If this does not fix the problem, the television will require repair by a qualified service center.

You have a PIN CUSHION problem, is usually a bad capacitor or open resistor in the above cicuit. Check all the caps around the horizontal output transister for ESR leakage.
