I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

SOURCE: 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 ..

There is over voltage from the voltage regulator section inside. You have to check out the reason for that. In most cased, the will be due to some loose solder terminals at this section.

    Tv in standby mode blinks 2 times then pauses and blinks again


    Hello
    Check your TVs power supply regulator section for any loose sodering points in it. The regulated voltage comes from it is more thatn normal. Check out all the soldering terminals. It is best to resolder all the suspected solder terminals by applying a little more solder, without making any solder bridge short in between adjecent solder points. The fault symptom as reported by sony is:-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.
    Check for any short circuit in the secondary section of the SMPS power supply section. Check the horizontal output transistor for collector to emitter short.
    OK.
