I have a Sony Projection TV KP-53v80. I tried to turn it on today bu there is no picture no sound. The Timer/Standby indicator flashes 4 times. What does this mean?


No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
Check IC1509, Q1505

It can be just an adjustment of your screen control. There is a "sweet spot" on the control where it allows the picture to come through. This is a common problem with sets that are getting old. If there is a problem with the high voltage from the color tubes then it will shut down the video until the problem is gone and it is safe again to show the picture. This is known as going into a shutdown procedure to protect the set. A technician will be needed to fix your problem since it will require proper troubleshooting and knowledge of high voltage system and safety procedures.

Sounds like one of the tubes is shorting out causing the set to go into a shutdown status so it won't cause any major damage to the set or house.

It's not a digital hi-def tv, so you either need a cable/sat box..or a converter once hi-def goes in and analog stops.

Heres how you get into the service menu. BUT be very careful write down anything that you change as this can screw your set up and if you write down everything you will be able to change it back if it affects your set. You may want to consider getting the service manual which will explain all the details on the convergence adjustments. If so let me know and I will post a link where you can get one along with free tech support to help you out with it.
Put the TV in Standby Mode.
  • Then press the following buttons on the remote:

    {DISPLAY} {5} {VOL+} {POWER}
    or
    {DISPLAY} {5} {POWER}
    or
    {DISPLAY} {5} {PICTURE} {POWER}
    or
    {DISPLAY} {5} {VOL+} {PICTURE} {POWER}

  • The TV will turn on with the Service Menu displayed.

  • Use numbers {1} and {4} to select the item to adjust.
  • Use numbers {3} and {6} to adjust the value of the data.
  • Press {MUTE} then {ENTER} to save new settings.
  • The words "WRITE" in red will show up in the upper right corner if saved.
  • Turn the TV off to exit the service menu.
