PHILIPS 32PFL5332: BLINKING ERROR CODES INFORMATION

ERROR -1
I2C bus 1 blocked.
TV will go to protection and the front LED will blink at 3Hz.  Now it can partially restart the TV via SDM shortcut pins on the SSB.  Depending on the software version it is possible that no further diagnose is possible.  With knowledge that only errors 1,2,4 and 63 result in a 3Hz blinking LED, the range of possible defects is limited.


ERROR -2
I2C bus 2 blocked.
  When this error occurs the TV will go to protection and the front LED will blink at 3Hz.  No can restart the the TV partially via the SDM shortcut pins on the SSB.  Due to hardware restriction [I2C bus 2 is the fast I2C bus]; it will be not possible to start up the VIPER and therefore, it is also impossible to read out error codes via ComPair or via blinking LED method.  With knowledge that only errors 1,2,4 and 63 result in a 3Hz blinking LED, the range of possible defects is limited.  When restarted the TV via the SDM shortcut pins and then pressed "CH+" on the remote control, the TV will go to protection again, and the front LED blink at 3Hz again.  This could be an indication that the problem is related to error-2.


ERROR-3
I2C bus 3 blocked.
There are only thre devices on I2C bus-3.  VIPER, Standby processor, and NVM.  Standby processor is the detection device of the error, so this will only occur if the VIPER or the NVM is blocking the Bus.  This error is also be logged when the NVM gives no acknowledge on the I2C bus.  Note that, if the 12V supply is missing [connector M46 on the SSB], the DC/DC supply on the SSB will not work.  Therefore, the VIPER will not get supplies and could block I2C bus-3.  So a missing 12V can also lead to an error-3. 


ERROR-4
I2C bus-4 blocked.
Error-4 is displayed in SAM.  No protection.


ERROR-5
Error-5 (Viper doesn't boot)
This error will point to a severe hardware problem around the VIPER [sypplies not OK, VIPER completely dead, I2C between VIPER  and standby processor broken etc:-.


ERROR-7
Error-7 (8-6V error)
Except a physical problem at the 8.6V itself, it is also possible that there is something wrong with the audio DC protection.  


ERROR-12
Error-12 (12V error)
Except a physical problem at the 12V itself, it is possible that there is something wrong with the audio DC protection.
