sony TV blinks

I have a sony rear projection TV model KP-53HS10. The timer/standby light flashes 5 times. Picture blinks, sound is normal. I have it plugged into a wall outlet and have unplugged it, waited and plugged it back in. It's normal for about 2 min and the 5 flashes reappear with no apparent pattern. Any help with the diagnostic code?

Is this a board a DIY can change.? Where is it located and/or where can I get a schematic?

A free schematic of this Sony

A free schematic of this Sony TV set can be downloaded from here:http://www.schematicsforfree.com/arch... Simply go to the website and find the Model number on the list and download for free. You are allowed I think one a month unless you pay a fee. The A-1346-873-A "D" board at my source( http://www.partstore.com/PartNumberSe... says this board is not available. A tech should be able to repair this board. Good Luck, and let us know how this repair turns out.

Before I call someone listed

Before I call someone listed with sony, is this a problem that can be fixed at the house or will the set have to go to the shop? Is this a board that I could spray some freeze over it to locate the faulty component and then change that piece? Any idea what this will cost to repair?

Thanks

Most likely in the shope as

Most likely in the shope as the TV set will need to be looked at with a schematic to see where the problem is. Unless you can read a schematic, use a multimeter, and trouble shoot solid state electronic printed circuit boards, you will not be able to repair this TV set. i doubt that freeze spray would help you in this repair, Good Luck and keep us posted on this repair.

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.

Check the HV regulator

Check the HV regulator transistor (Q8008) may have  a Gate to Source short.

If this was one of our small sets I'd like to experiment with it but being this is the main expensive set I'll leave to the pro's and stay out of the dog house. I'll post a thread when it's finished.

negrito, Four blinks - No

negrito, Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505.  This could also be because of a bad capacitor or the vertical output IC.  You will need to get the service manual for this set to find where all the Parts are located my friend.
  Good Luck and let us know if you get thisn TV set repaired and what the problem(s) were.

I have a sony kv32fs120. It has no picture but has 5 blinks on the standby red light. Two t.v. repair guys stopped by and told me it was the flyback transformer' they said it would be more economical to do it myself and showed me how. my question is this, 5 blinks stands for akb video patch. not to question them but before i purchase the wrong thing which is it and where can i purchase it
