Extra Info

•

Rebooting. When a TV is constantly rebooting due to

internal problems, most of the time no errors will be logged

or blinked. This rebooting can be recognized via a ComPair

interface and Hyperterminal (for Hyperterminal settings,

see paragraph "Stand-by software upgrade). You will see

that the loggings which are generated by the main software

keep continuing. In this case (rebooting) diagnose has to

be done via ComPair.

•

Error 3 (I

C bus 3 blocked). At the time of release of this

manual, this error was not working as expected (error 3 is

logged and can be read out). Current situation: when this

error occurs, the TV will constantly reboot due to the

blocked bus. The best way for further diagnosis here, is to

use ComPair (e.g. read out the NVM content). Instead of

error "3" it is possible you will see error "2" in the error

buffer.

•

Error 5 (PNX8535 doesn't boot). Indicates that the main

processor was not able to read his bootscript. This error will

point to a hardware problem around the PNX8535

(supplies not OK, PNX 8535 completely dead, I

between PNX and Stand-by Processor broken, etc...).

When error 5 occurs it is also possible that I

blocked (NVM). I

C2 can be indicated in the schematics as

follows : SCL-UP-MIPS, SDA-UP-MIPS, SCL-SLAVE,

SDA-SLAVE, SCL-2 or SDA-2.

•

Error 11 (I

C MUX1). Indicates a blocked (short-circuited)

C-MUX1 bus. At the time of release of this manual, this

error was not working as expected.

•

Error 12 (I

C MUX2). Indicates a blocked (short-circuited)

C-MUX2 bus. At the time of release of this manual, this

error was not working as expected.

•

Error 24 (I

C switch). As a side effect of error 24 it is

possible that error 47(no existing error) will also be logged.

•

Error 28 (DFI Ambilight MOP). It can take up to 2 minutes

or more before this error is logged. So if you suspect that

this MOP is defective: clear the error buffer, restart the TV

and wait for about 2 minutes before checking the error

buffer.

•

Error 37 (Channel decoder). When this error occurs,

there probably will be no picture and sound from tuner

input. As a side effect of error 37 it is possible that error 4

(no existing error) is also logged.

Error 46 (Pacific 3). When there is an actual problem with

or around the Pacific during start-up, you will have no

picture and error 46 will be blinked via the blinking LED

procedure. For further diagnosis you can always dump the

CSM content on USB stick (see CSM) or use ComPair.

•

Error 53. This error will indicate that the PNX8535 has

read his bootscript (if this would have failed, error 5 would

blink) but initialization was never completed because of

hardware 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). Note that it can take up to 2 minutes

before the TV starts blinking error 53.

•

Error 63 (POWER OK). When this error occurs, it means

that the POWER-OK line did not became "high". This error

is only applicable for TV's with an LCD display. For PDP

displays there will be no protection during a POWER-OK

line failure, but error 63 will be logged in the error buffer.

Caution: in case a PDP TV ends up into power-ok

protection, it can indicate that the display option code is set

to "LCD". To change the display option code to "PDP" you

need to activate SDM via the service pads (see figure

"Service mode pads"). Then change the display option

code blindly via a standard RC : key in the code "062598"

directly followed by the "MENU" button and "XXX" (where

XXX is the 3 digit decimal display option code as

mentioned in figure "Display option code overview").

•

Error 65 (DFI EPLD error). When this error occurs it

means that there is a problem with the I

towards the EPLD (picture processing EPLD, not the

Ambilight EPLD) on the DFI panel.
