Protection (after 3 minutes) + Error blinking

 Error 1 (I2 C bus 1 blocked). When this error occurs, the TV will go to protection and thefront LED will blink at 3 Hz. Now you can partially restartthe TV via the SDM shortcutpins on the SSB. Depending on the software version it is possible that no further diagnose (error code read-out) is possible. With the knowledge that only errors 1, 2, 4, and 63 result in a 3 Hz blinking LED, the range of possible defects is limited.

Error 2 (I2 C bus 2 blocked).When this error occurs, the TV will go to protection and thefront LED will blink at 3 Hz. Now you can partially restartthe TV via the SDM shortcut pins on the SSB. Due to hardware restriction (I2 C bus 2 is the fast I2 C bus) it will be impossible to start up the VIPER and therefore it is also impossible to read out the error codes via ComPair or via theblinking LED method. With the knowledge that only errors 1, 2, 4, and 63 result in a 3 Hz blinking LED, the range ofpossible defects is limited. When you have restarted the TVvia the SDM shortcut pins, and then pressed "CH+" on your remote control, the TV will go to protection again, and the front LED blink at 3 Hz again. This could be an indication that the problem is related to error 2.

Error 3 (I2 C bus 3 blocked).There are only three devices on I2 C bus 3: VIPER, Stand-by Processor, and NVM. The Stand-by Processor is the detection device of this error, sothis error will only occur if the VIPER or the NVM is blocking the bus. This error will also be logged when the NVM gives no acknowledge on the I2 C bus (see error 44). Note that if the 12 V supply is missing (connector 1M46 on the SSB), the DC/DC supply on the SSB will not work. Therefore the VIPER will not get supplies and could block I2 C bus 3. So, a missing 12 V can also lead to an error 3.

Error 4 (I2 C bus 4 blocked).Error 4 is displayed in SAM. No protection.Error 5 (Viper doesn’t boot). This error will point to a severe hardware problem around the VIPER (supplies not OK, VIPER completely dead, I2 C link between VIPER and Stand-by Processor broken, etc. ...).

Error 7 (8.6 V error). Except a physical problem with the 8.6 V itself, it is also possible that there is something wrong with the Audio DC Protection: see paragraph "Hardware Protections" for this.

Error 12 (12 V error). Except a physical problem with the 12 V itself, it is also possible that there is something wrong with the Audio DC Protection: see paragraph "Hardware Protections" for this.

Error 14 (Audio supply). This error is triggered in case of  too low voltage of the audio supplies and therefore a drop of the audio supply voltage of below approx. 9 V per supplyrail (or lower than 18 V rail to rail). Also a DC voltage of higher than 1 V DC on the speakers will lead to protection and error 14 blinking. For LCD sets this circuit can be foundon schematic SA3, for PDP sets this can be found on schematic C. It should be noted that for 26-inch models there is only a supply link between the amplifiers and thestand-byμ C whereas in all othermodels this link is implemented by Audio-Prot line pin 7 on 1 M02.

Error 18 (MPIF1). Error 18 is displayed in SAM. No protection

Error 21 (HDMI switch). Error 21 is displayed in SAM. No protection.Error 25 (Supply fault). When this error occurs, the TV will go to protection and the front LED will blink at 3 Hz.

Error 29 (AVIP1). This error will probably generate extra errors. You will probably alsosee errors 32 (MPIF) and error 31 (AVIP 2). Error 29 and 31 will always be logged together due to the fact that both AVIPs are inside the PNX2015 and are on the same I2 C bus. In this case start looking for the cause around AVIP (part of PNX2015).

Error 31 (AVIP2). See info on error 29.

Error 34 (Tuner 1). When this error is logged, it is not sure that there is something wrong with the tuner itself. It is also possible that there is something wrong with the communication between channel decoder and tuner. See schematic B2B.

Error 37 (Channel decoder). This error will always log error 34 (tuner) extra. This is due to the fact that the tuner I2 C bus is coming from the channel decoder.

Error 44 (NVM). This error will never occur because it is masked by error 3 (I2 C bus 3). The detection mechanism for error 3 checks on an I2 C acknowledge of the NVM. If NVM gives no acknowledge, the stand-by software assumes that the bus is blocked, the TV goes to protection and error 3 will be blinking.

• Error 53. This error will indicate that the VIPER has started to function (by reading his boot script, if this would have failed, error 5 would blink) but initialization was never completed because of hardware peripheral problems (NAND flash, ...) or software initialization problems. Possible cause could be that there is no valid software loaded (try to upgrade to the latest main software version)
