Question about Sony FD Trinitron WEGA KV-36HS500 36" TV

1 Answer

Sony wega trinitron won't turn on

Our tv worked fine until last night. Now, it won't turn on. It is receiving power and the tv tries to click on; but the screen doesn't get that
static-y sound. Then, five red blinks (4 blinks and a very short 5th blink, actually), and ... nothing. The TV is a Sony FD Trinitron Wega, Model # KV-32XBR400. Thanks.

  • 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.
  • and some times the eprom ic is fulty ...
  • try to unplug your tv from the main power for 5 hours then press the power button and keep pressing for 7 seconds then release ,if this do not work ,you should take your tv to a qualified person
  • i hope this helps ..

    Sounds like a problem with the vertical circuit. If yuo can solder and are comfortable with working inside the set, you may be able to repair this.

    Keep us posted.
