    Yea I read that. Can't locate said parts. Check C515 & 516 and the jungle IC, IC206.
    When I search my manual is pdf., it doesn't come up. Spent 1.5 searching the board for them and don't see them. I'm not very familiar with the manual and terminology. Can you help further?

    I do appreciate it

    Thanks again!

Right from the Sony manual, sounds like you know what you are doing

Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.


Let me know how this turns out.

    This indicates that you should look at three components: 2 caps and an IC. The C515 and C516 are capacitors the the IC 206 is an integrated circuit.


    Radio Shack will have the parts

    The fault and parts lie within the horizontal circuitry. It is pretty
    complicated to dig into this section unless you are a trained tv
    expert. It will still require some investigation to determine the
    exact problem area. The jungle IC spoken of in the Sony blink code is
    a monster that operates over a hundred circuit functionalities. It has
    inside almost 1 million transistors. So, it takes some skill to check it or replace it.

Sony Trinitron Problems - Red light blinks 6 times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully.Visit this site " Electro help "for more details. Google for it.
It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

The 7 blinks on this model indicates that the horizontal section of the TV has stopped working. Horizontal Deflection Stopped

Occurs when either:

1) a +B overcurrent is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).

I have the serrvice manual if you need it. Let me know where to send it to.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sony KV-32HS420 will not come on has blinking standby light


Get out your original remote and hold the "Setup" button at the same time as holding the On/Off button on the TV set. It just worked for me!! Thank goodness. I was just about to bring it for repair but there's a snowstorm. Here's the link I got this from: http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=http--esupportsonycom-perl-tutorial-displaypltutid297templateid1regionid1KSMFlag7370&sliceId=&docTypeID=DT_TUTORIALS_1_1&dialogID=53101564&stateId=0%200%2053105132
