No proper test equipment required for this. The Scaler board has failed and is not repairable with the equipment shops have. (The IC's that have failed for this problem requires a $10,000 computer operated soldering and desoldering machine to remove and replace and the IC's which, unless purchased in a large enough quantity, cost way too much.)

Answer: Purchase part number 313815866271 from Andrews, MCM or Vance Baldwin. If you have a business license, Andrews has the best price. (215.00 + 150 Core with license or 306.24 + 150 core without.)

This is NOT the crystal problem.

Hope this helps.
