Default Sony KV-24FS120 Video Blanking (and what is IK Shutdown?)

Hi Everyone,

Here's the scoop. I've got a Sony KV-24FS120 TV which after being on
for several hours, begins to blank the video for several seconds while
flashing what I understand is a diagnostic code, then pops the video
back on. Once the cycle starts, it does not stop. The interval between
blank screens appears to depend on the brightness of the picture. While
all this is happening, the audio is fine, and I do not notice any
stopping of the HV whistle.

If I understand the diagnostic blinking correctly, the problem is B+ OCP
(blinking twice), and B+ OVP (blinking three times). With each
fault, either two or three blinks occurs. Once or twice the LED blinked
four times.

Bringing up the diagnostic screen (Disp, 5, Vol-, Pwr), lists the
following information:

2: +B OCP 0
3: +B OVP N/A
4: VSTOP 0
5: AKB 1
101: WDT N/A

Yup, I agree these settings don't agree totally with the # of blinks.
When I first noticed the blinking pattern (I'm new to this whole
diagnostic blinking thing), there **may** have been one time it blinked
five times (explaining the AKB '1').

So, with all my hot air above, are there any suggestions?

Also, just what does the "IK" in "IK Blanking" mean? I've Googled and
Googled, but no definitions.

Thanks a bunch!
