Most commonly, the power supply, and or scan failure causes this. There may be some bad caps, in these areas. In the horizontal output area, the flyback and the horizontal output transistor may also be defective. There may also be some damage to the power supply in this case.

I have a sony wega trinitron, when the tv is turned on, (no visual, or sound) the red stand by light blinks 7 times, and you hear the tv click off? Please help


Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Here's my suggestion , unhook all the external components to the TV and leave the TV unplugged for more than a few minutes (a day/overnight). The next day plug the TV into the wall outlet (not the powerstrip) without anything hooked up to it, and turn it on. See if it comes on. Sometimes unplugging for a few minutes/hours is not long enough for it to reset itself.

Sony wega trinitron won't turn on


  • 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 ..
