Hack Your Sony Big Screen

By Seth Kintigh

In the beginning there was a TV.  Well, before that there was a Seth.  And God wanted Seth to have that TV (long story, just trust me on this).  Unfortunately the TV God wanted Seth to have was from Building 19, so it wasn't perfect.  So Seth had a tech look at it and order new parts (on Sony.  I love Sony - they also fixed a cd player of mine that was out of warrantee).  Seth also asked the tech to make a few adjustments to the screen, so the tech attempted to enter the Diagnostic Mode of the TV.  It took a few tries and Seth was able to memorize the code (users are not allowed access to these sacred codes - only techs).  And so Seth went forth and hacked his TV.  He reverse-engineered many of the functions, and then following The Meaning Of Life* he created this web page to share this holy knowledge with all.

* The Meaning Of Life (as told to me by Prof. Vaz (EE, WPI) as told to him by ???)

  1. Tell everyone everything you know.
  2. Work like hell <-- love it.
  3. Have fun.

He also told me that sparks are 30 kV/cm.  Ouch.

My tv is the KP-53S65 53 inch Sony big screen television.  I'm sure this info pertains to other TVs of the S65 series and most likely to many other Sony TVs.  Let me know.

For some reason you may have to unplug your TV for a few seconds before these codes will work.  Having done that, to enter the diagnostic mode you press on the remote (in order, not all at once):

Congratulations, you are now in service mode and the top of your screen reads something like

SERVICE IC SSCN 4
0000 0

SERVICE means you are in service mode.  IC is the function group you are in of 8 categories.  SSCN is the function of that group (IC) of 3-96 functions.  4 (or perhaps a different number for you) is the current setting of that function (SSCN).

Most of the buttons on your remote still act the same, with the following exceptions:
1: Scrolls up one function
4: Scrolls down one function
2: Scrolls up one category
5: Scrolls down one category
3: Increments current setting
6: Decrements current setting
7: null
9: null?
Jump: null?

8: Resets settings (to those in non-volatile memory?)
0: Reads (from save?) settings
Mute: Write settings to non-volatile memory
Enter: Confirms Reset, Read and Write.

What I learned

Undoing the damage

I thought I had my convergence perfect after a month of tweaking.  Then I bought a DVD player and watched Contact in letterbox.  Rather than tweak more I decided to start over.  In case you screw things up so bad that you don't know what you're doing anymore (i.e. you turn off the green cannon) here's how to fix it:

Unplug for a few seconds then press:

Wait a few seconds.

This resets everything (?) back to the way the factory ships it to the stores.
