Sony Trinitron KV-SP29M53K- RM-GA002, KV-SP29M83K- RM-GA002, KV-SP29N63K- RM-GA002 – Service mode, Service adjustments, full Schematic, Disassemble procedure
Self-diagnostic function.
If an error occurs, the STANDBY Indicator will automatically begin to flash.
The number of times the STANDBY Indicator flashes translates to a probable source of the problem.If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a “0”.
HANDLING SELF DIAGNOSTIC SCREEN DISPLAY
OCP - +B overcurrent - Occurs when an overcurrent on the +B(135V) line is detected by pin 32 of IC001 (A board).
If the voltage of pin 32 of IC001 (A board) is more than 4V, the unit will automatically go to standby.
V-Protect - Occurs when an absence of the vertical deflection pulse is detected by pin 13 of IC001 (A board).IK (AKB) - If the RGB levels do not balance for 15 sec after the power is turned on, this error will be detected by IC001 (A board).
TV will stay on, but there will be 5 times LED blinking.
Power supply NG (+5V) for video processor - Occurs when IC001 internal HV protect detects an abnormal H-Pulse (frequency) due to improper power supply to IC001. TV cuts off high voltage power of anode CRT.
No picture will be detected. eg: IC602, IC604 go faulty.
