    The light blinks 3 I have to screw the back of the TV off? where do I get parts?

  • SACRIFICE Jul 10, 2008


    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

  • SACRIFICE Jul 10, 2008

    yes I got that info from another site and wanted to verify it. Thanks! now the next step for me is to find out what those parts are, what they look like and where to get them.

    i have the same problem with my kv-27s42 sony.

    1) does T603 mean transister 603?

    2) does R622 mean resistor 622?

    3) are these solid state components in a solid state circuit board? if so, do i have to replace the whole board?

    4) will i have to drain the crt? if so, how?

Could be a memory error .try to turn on the tv after you extract it.If it is no change, than verify final flyback transistor (replace it).make sure that the power supply have the right tensions on secondary(could be higher than normal).

The standby light should be flashing in a repeated count. That is what happens when the set detects a problem and enters a protective shutdown. The blink count will indicate the circuit in which the problem was detected. Please post that count and I should be able to provide you with details.

    Yes, that information is correct. I don't have the manual with me at the moment, but that posting (from another site) is accurate. The part designation should be close if not exact. Please ignore the response from "guest" as that info is incorrect.



  • ABRsvcs Jul 10, 2008

    I'll look up the parts in the service manual and post the part numbers and source here.

Try unpluging your T.V. for 5hours+, then turn it back on. Worked for It's called a "hard reset" by sony.

Do the following steps
  1. Check the Sony remote for a button labeled "Sleep." This allows you to cycle through the sleep settings and determine how long you want the TV to remain on.
  2. Step 2 Press the "Sleep" button. You'll see a number come up onscreen: usually 15 or 90. When you press it again the number changes, moving up and down in increments of 15. This is the number of minutes the TV will remain on before it goes to sleep. As you cycle through it, you should see a setting with the words "Sleep Off" appear onscreen. If you leave it there, the sleep setting should cancel, allowing you to turn the set off when you like. If you miss it, just keep pushing the "Sleep" button. It will continue to cycle through the options until "Sleep Off" appears once again.
  3. Step 3 Access the timer function to shut off the timer by pressing the "Menu" button, then cycling through the onscreen options until you reach the "Applications" setting. Press it, and then cycle through to the "Clock/Timers" option.
  4. Step 4 Highlight the "Timer 1" setting and press the "+" button. If it's showing a given time, you'll need to deactivate it. Use the up and down arrows and move through the possible options until you come to the "Off" setting. Leave it there; that should shut the timer off.
  5. Step 5 Repeat the process with the "Timer 2" setting, a little further down the "Clock/Timers" menu. Set it to the "Off" position just as you did with the "Timer 1" setting.
  6. Step 6 Press the "Menu" button when you are done to exit the menu and return to the screen. You should be able to view the Sony TV as normal with no danger of it turning off.

good luck

Sony trinitron kv-27ts20 wont turn on

This problem may come from a bad capacitor in the standby power supply. The part location is C605

This should be an easy fix.
