The verticaloutput section of your TV ahs the fault. You have to contact any expereinced service technician, or the authorised service center for Sony, to rectify this fault.

The problem is in the power supply, the most common cause is an open fuse and open capacitors, if the set is more than 10 years old consideration should given in replacing the tv especially if a professional gets involved.

  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  • One blink - not used for the self-diagnosis
  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
  • 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.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
  • 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.
  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

  • Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).
  • Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Good day!

Unfortunately,the board/chassis is not available at any store online....only spare parts!!

but if you want to fix your problem on your own I'm here to teach you how to do that..

  1. Open the back cover of your TV..
  2. check the B+ supply (it is usually located at the 3rd pin of ply-back.
  3. if you don't have B+ the problem could be on the power supply section..check the possible open resistor and shorted diode and transistor..
  4. If you have B+ supply but it cut off,,please try to hang the connection of it then try to check again if it is stable when it hang the problem is the ply-back transformer..please replied it with the same type and part #..
  5. If you have voltage in B+ and the ply-back is not switch..The problem could be the Jungle I.C..please replaced it..
That is the possible trouble on your TV..please try to do that..
You have a better chances if you have failing capacitors on the chassis..
Look the actual image of it..If looks like leak/bulged on the top and bottom and sometimes have a oil on the based...please replaced it with the same value,type and ratings (uf)microfarad..

hope it helps....thank you..
