REPAIRING AND NOT THROWING AWAY

REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

PHILIPS QFU2,2E LA CHASSIS LCD TVS [PFL SERIES] - ERROR CODE OVERVIEW - DETAILS

PHILIPS [PFL Seires]  QFU2,2E LA CHASSIS LCD TVs  - ERROR CODE OVERVIEW - DETAILS


ERROR CODE OVERVIEW
CLICK ON THE TABLE TO ZOOM IN
Error Codes Details
Error 13 (I2C bus M3, SSB + SRF bus blocked). Current  situation: when this error occurs, the TV can reboot due to the blocked bus. The best way for further diagnosis here, is to check the logging output.
Error 14 (I2C bus M2, BE bus blocked). Current situation:  when this error occurs. The best way for further diagnosis here is to check the logging output.
Error 15 (Fusion doesn’t boot). Indicates that the main processor was not able to read his boot script. This error will point to a hardware problem around the Fusion (supplies not OK, Fusion device completely dead, link between Mips and Stand-by Processor broken, etc...)
Other root causes for this error can be due to hardware problems regarding the DDR’s and the boot script reading from the Fusion device.
Error 16 (12V). This voltage is made in the power supply and results in protection (LAYER 1 error = 3) in case of absence. When SDM (maintain grounding continuously) is activated we see blinking LED LAYER 2 error = 16.
Error 17 (Display Supply). Here the status of the “Power OK” is checked by software, no protection will occur during failure of the display supply, only error logging. LED blinking of LAYER 1 error = 3 in CSM, in SDM this gives LAYER 2 error = 17.
Error 18(I2C bus M1, FE bus blocked). Current situation:  when this error occurs. The best way for further diagnosis here, is to check the logging output.
Error 23 (HDMI mux). When there is no I2C communication towards the HDMI mux after start-up, LAYER 2 error = 23 will be logged and displayed via the blinking LED procedure if SDM is switched on.
Error 24 (I2C switch). When there is no I2C communication towards the I2C switch, LAYER 2 error = 24 will be logged and displayed via the blinking LED procedure when SDM is switched on.
Error 27 (Channel dec DVB-T2). When there is no I2C communication towards the DVB-T channel decoder, LAYER 2 error = 27 will be logged and displayed via the blinking LED procedure if SDM is switched on.
Error 28(Channel dec DVB-S2). When there is no I2C communication towards the DVB-S channel decoder, LAYER 2 error = 28 will be logged and displayed via the blinking LED procedure if SDM is switched on.
Error 31 (Lnb controller). When there is no I2C communication towards this device, LAYER 2 error = 31 will be logged and displayed via the blinking LED procedure if SDM is activated.
Error 34 (Tuner). When there is no I2C communication towards the tuner during start-up, LAYER 2 error = 34 will be logged and displayed via the blinking LED procedure when SDM is switched on.
Error 35 (main NVM). When there is no I2C communication towards the main NVM during start-up, LAYER 2 error = 35 will be displayed via the blinking LED procedure when SDM is switched “on”. All service modes (CSM, SAM and SDM) are accessible during this failure,
observed in the Uart logging as follows: "<< ERRO >>> PFPOW_.C: First Error (id19,Layer_1= 2 Layer_= 35)".
Error 36 (Tuner DVB-S). When there is no I2C communication towards the DVB-S tuner during start-up, LAYER 2 error = 36 will be logged and displayed via the blinking LED procedure when SDM is switched “on”.
Error 37 (Class-D). When there is no I2C communication towards the Class-D amplifier during start-up, LAYER 2 error = 37 will be logged and displayed via the blinking LED procedure when SDM is switched “on”.
Error 38(FPGA ScanBacklight). When there is no I2C communication towards this FPGA device during start-up, LAYER 2 error = 38 will be logged and displayed via the blinking LED procedure when SDM is switched “on”. This device supports the backlight + boost pwm control,
scanning, 3D drive and ambilight buffering.
Error 42 (Temp sensor). Only applicable for TV sets equipped/stuffed with temperature devices.
Error 43 (Light sensor). When there is no I2C communication towards the light sensor device during start-up, LAYER 2 error = 43 will be logged and displayed via the blinking LED procedure when SDM is switched “on”.
Error 44 (Touch control). When there is no I2C communication towards the touch control micro processor during start-up, LAYER 2 error = 44 will be logged and displayed via the blinking LED procedure when SDM is switched “on”.
Error 46 (RF4CE). When there is no I2C communication towards the RF4CE driver during start-up, LAYER 2 error = 46 will be logged and displayed via the blinking LED procedure when SDM is switched “on”.
Error 53. This error will indicate that the Fusion device has read his boot script (when this would have failed, error 15 would blink) but initialization was never completed because of hardware problems (NAND flash, DDR...) 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 a few minutes before the TV starts blinking LAYER 1 error = 2 or in SDM (maintain grounding continuously), LAYER 2 error = 53.
