A service manual for your model/chassis series is available (free PDF - 100% clean).

It sounds like a blank raster with retrace lines (no picture) which would be some kind of video fault. You could check C-board (Video OUT (IC9001-IC9003)) and progress from there. Also, being a CRT set, there may be a few bad solder joints everywhere - especially around the flyback transformer, and, with set unplugged, look for ruptured or bulging electrolytic capacitors in the video, vertical and HV areas of the chassis. Also check the horizontal output transistor(s) and associated tuning capacitor(s) to make sure they are OK (if they are, you can rule them out as suspects). It's a start.

  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

    SOURCE: Problem for Sony Grand WEGA KDF-55WF655. Hello,

    5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
    2 possible reasons, either Lamp is gone or Ballast Supply got bad.
    Replace lamp first, in most cases it solved the problem.
    How old is this TV and did you replaced lamp recently?
    Thanks.

    I have a sony trinitron kv-32xbr400 it works but the picture is almost like its out of focus it has lines running thru it


    The description that you give indicates a video problem, it is a situation where the picture tube is over driven and makes the picture bloom and produces white lines on a angle, this is caused by an open resistor or a shorted video driver usually located on the back of the picture tube, "video board"

    Sony 32" xbr trinitron trusurround T V picture is black


    Most likely on a trinitron tube if it is dark is the high voltage capacitor has blown. This is the device that feed the 30,000 or so volts to charge the tube, it attaches at the back with a clip and ****** and a single cable coming from it.

    You can check easily if it is definately that as you will notice if you power the tv on and off once or twice if you get that static charge feel from the screen, if there is none there then almost certainly that is the problem.

    KV-32xbr400 switch problem


    Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it. in yor case you have 5 blinks that´s why the last is short to be possible the count..Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

    There are no hazards, Just a Picture tube trying to tell you something. The tube is defective. There is no way to fix it, but to replace the tube. To replace the tube is not cost friendly. Cost of tube $707.00 part number 8-735-047-05
