Sony Trinitron CRT reset default service menu settings?

[bytestorm]

Hi!

I got a really nice KV-14LM1x CRT with a FE-2 chassi that my friend accidently made into a paperweight when he was in the service menu.
Now it only shows an error code of 5 blinks from the diode and that means unstable AKB. (the RGB values are totally off or something I read in another forumpost.)

Anyhow, I cant get anything to display at all, not seeing if I can enter into the service menu either.. so my thoughts are, can I somehow reset the settings to factory default or something? Without seeing any menu? I have the service manual and will open the TV soon, but I cant think that its defective since it just turned off suddenly when he was in the service menu "checking around".

Should be some eeprom or such holding all the settings.

Anyone experienced this 5 blink syndrome before?

Thanks in advance
