  • Page 5: Warning And Cautions

    Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. Circuit adjustments that are critical for safe operation are identifi ed in this manual. Follow these procedures whenever critical components are replaced or improper operation is suspected.
  • Page 6: Safety Check-Out

    KV-34FV310/38FV310 SAFETY CHECK-OUT Leakage Test After correcting the original service problem, perform the following The AC leakage from any exposed metal part to earth ground and from safety checks before releasing the set to the customer: all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes).
  • Page 7: Self-Diagnostic Function

    KV-34FV310/38FV310 Self Diagnosis SELF-DIAGNOSTIC FUNCTION Supported model The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to fl ash. The number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY/TIMER LED fl ash indicators is listed in the instruction manual for the user’s knowledge and reference.
  • Page 8 KV-34FV310/38FV310 Stopping the Standby/Timer LED Flash Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER LAMP from fl ashing. Self-Diagnostic Screen Display For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confi rmed, it is possible to bring up past occurrences of failure on the screen for confi...
  • Page 9 KV-34FV310/38FV310 +B overcurrent (OCP) Occurs when an overcurrent on the +B (135V) line is detected by pin 48 of IC001 (A Board). If the voltage of pin 48 of IC001 (A Board) is less than 1V when V.SYNC is more than seven verticals in a period, the unit will automatically turn off. +B over voltage (OVP) Occurs when a high is felt onpin 2 of IC501 (A Board).
