My tv when on turns red blinks six times and off

Not sure if you can see this, but I have a KDL46XBR5 and this is the self diagnostic function listed in the service manual.

Six red blinking lights, pause, six more lights may indicate a faulty backlight or a problem related to your backlight. This doesn't necessarily mean you have to replace anything, could be a ground screw is loose, or one of the many cable connectors need to be reseated while the unit is off. See attached to see if this helps.

If not, google "self diagnostic function kdl-37m4000" and see if that helps. At least this should point you in the right direction

Power supply tv

Only between exact same models. Even then some models have several different versions depending on type of LCD panel used. If you have another power supply from the same model and all the plugs are the same you should be fine.
