If it is the security code you are looking for, try these solutions. See how you get on. Solutions that have been tagged as workers... try the soft fix first, then if your game,the 4 blob trick... dunno bout that one??

 I recall changing out the 8 pin eeprom chip where the security code was stored on Sony and Pioneer Head units where customers had forgotten their code when the units were brought in for service, so  you start with a fresh code. That was a few years back but:).  
Will have an 8 pin dip chip as detailed in this post if thats the case for this unit. You may need to supply your Identification toSony to order the part. This is how it used to be,and it may be doable only at a sony agent, this being a security part for the unit. Let me know howyouget on.

Lost code for sony cdx-m800


You can enter a 4-digit security code as an option after purchase of the unit. If you do so, make sure it is noted down somewhere. If you did select a code (or the previous owner has done so) this must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational. If the code is lost or forgotten I am afraid the unit has to be re-coded by a Sony dealer.
Hope this helps, Good luck with it.

Black out


this is a coincedence. The CDX-M800 had a HUGE problem with the ribbon cable on the face going bad, causing this exact problem.
$14.00 and some time will put it back into perfect condition.
