ICT222 pincushion issues do you have schematics?


Schematics are never available for free. In printed form, they are sold in bundles with those from several sets packaged together. This is why service technicians are the only ones who usually buy them. In machine readable form, they are available as part of a subscription database service; again, too costly for an individual.
Even with schematics, it is DANGEROUS to work on the inside of a projection TV. There are High Voltages which can persist for WEEKS after the set is turned off.
Even if you could find and replace the bad part, readjusting the pincushion settings usually takes special instruments. Unless you are planning this as the start of a new career, you had better call a service technician.

Circuit diagrams are available online from 5-20 dollars. I doubt it will do you much good, as you will need to be an expert at tv repair in order to read the diagram, and trace the problem. It sounds to me like a bad capacitor near the horizontal deflection circuits, or a resistor near the pincushion adjustment could have blown. If you really want to learn how to fix your tv, you should visit some learning websites that explain the different areas of a tv circuit board and their functions.

Have you ever had this problem?


Generally,pincushion may be driven by a chip or IC,but pin out is normally a durable xistor. Servicer adjustments are minor for pin correction.Go to pin out circuit & measure voltages.Get back to me on your findings.
