Therefore, a power-cycle should reset any destroyed settings as long as you DO NOT save them to memory. NOTE: Changes made to settings while in service mode are not stored into memory unless explicitly requested. All buttons should be pressed within 1 second of each other.

Service Mode via On-Screen Display: In order to bring up the service mode OSD, turn the TV on from standby mode using the following sequence of buttons on the remote control. Needless to say, if incorrect settings are applied through service mode, the TV can be pretty severely messed up or even bricked! CONSIDER YOURSELF WARNED!!! The settings / registers which can be programmed from the service mode adjust everything from picture size to scanning frequency and phase to RF tuning. The KD-34XBR960 and family have a built-in 'Service Mode' which allows extremely in-depth and low-level programming of the main microprocessor. the main microprocessor locked-up and the watchdog timer forced a hardware reset to occur. either B+ overcurrent was detected by IC5007 or Thermistor TH5002 detected an overheating condition. H-STOP : Horizontal deflection stopped.this means that the set's +5V power supply is overloaded or out. RGB levels did not balance within 2 seconds of power-on. The power supply will be shut down after 2 seconds in this condition. detected by IC2801, pin 24 (on Board BY). VSTOP : Vertical deflection pulse has stopped.As a result, transistor Q6522's output has gone high and the AC relay has been shut off. As a result, transistor Q5004's output has gone high. excessive current has flown through resistor R5013. More info about the errors is shown below: All error logs can be cleared by pressing Channel '8' -> 'ENTER' on the remote control while in the self diagnostics OSD.

The left column shows the Error code ID number and name, and the far right column shows the number of times that each error was recorded. When the TV powers up, the On-Screen Display labeled 'SELF DIAGNOSIS' will appear. 'DISPLAY' -> (Channel) '5' -> Volume Down '-' -> Power 'ON'. Self-Diagnostics via On-Screen Display: In order to bring up the self-diagnostics OSD, turn the TV on from standby mode using the following sequence of buttons on the remote control. Or Integrated Circuit IC504 is faulty (Board AZ). +5VDC Line is overloaded (Boards AZ, BY, MZ). Or Screen/G2 potentiometer is mis-adjusted. Or Integrated Circuit IC2801 is faulty (Board BY). Integrated Circuits IC9001-9003 are faulty (Board CX). Integrated Circuit IC5004 is defective (Board DZ). Integrated Circuit IC6505 is defective (Board DZ). Transistor Q5030 or Q5003 (Board DZ) is shorted out. A table of the flashing codes is shown below. If any immediate errors are detected, they will be displayed through flash codes on the TV's 'Standby' LED. Self-Diagnostics via Standby LED: During power on, the TV will automatically run self-diagnostics. The self-diagnostic mode output can be viewed either through the 'Standby' LED on the front of the TV set, or through the self-diagnostic OSD (on screen display). The KD-34XBR960 and family have a built-in self-diagnostic mode which can help identify previous or current electrical / electronic faults within the TV. A secondary problem with this set was that the variable focus was slightly off and the image was being excessively over-scanned. The main problem with the TV when I purchased it was that it would shutdown and/or reboot sporadically during use. I recently picked up a 'broken' KD-34XBR960 off craigslist, and this page documents my efforts to repair and properly calibrate this beautiful TV back to its original (or better) condition. NOTE: The information presented here also generally applies to Sony models KD-30XS955, KD-34XS955, and KD-36XS955. It is manufactured using Sony's 'WEGA' and 'Trinitron' technologies, and is compatible with resolutions up to 1920x1080 interlaced (HD1080i). The Sony KD-34XBR960 is a high definition, CRT television set manufactured in the early to mid 2000s. Service, Repair, and Calibration of an older HDTV.
