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 52HFL5580 SERVICE MODE AND ADJUSTMENTS

PHILIPS 52HFL5580D/27  Service mode and adjustments

Philips 52HFL5580

Hotel mode
Before the service modes can be activated, the set needs to be switched into normal consumer mode (MTV-Mode) first. Use an iTV setup remote control (type: RC2573/01, 12nc: 3139 228 88782) to key in the code ‘024995’ (slowly) directly followed by the MENU button. The text messages “TV Is Now In MTV Mode” and “Please Do A Cold Start!” appears on the screen. Disconnect the set for a few seconds from the mains supply, reconnect the set to the mains supply again. The set is now in the normal consumer mode (MTV-Mode). After repair, place the set into hotel mode (iTV-Mode) again. Key-in the same code on the remote control as described above. The text message “TV Is Now In ITV Mode” appears. A cold start must be performed as described above. The set is now in the hotel mode (iTV-Mode) again.
Service Modes
Service Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer.
Service Default Mode (SDM)
Purpose
# To create a pre-defined setting, to get the same measurement results as given in this manual.
# To override SW protections detected by stand-by processor and make the TV start up to the step just before protection (a sort of automatic stepwise start up). See paragraph “Stepwise Start Up”.
# To override SW protections detected by MIPS. See also paragraph “Error codes”.
# To start the blinking LED procedure (not valid for protections detected by standby software).
How to Activate SDM
For this chassis there is one kinds of SDM: an analogue SDM Tuning will happen according table “SDM Default Settings”.
# Analogue SDM: use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” button.
Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” button again.
# Analogue SDM can also be activated by shorting for a moment the two solder pads on the SSB, with the indication “SDM”. Activation can be performed in all modes, except when the set has a problem with the Standby Processor. After activating this mode, “SDM” will appear in the upper right corner of the screen (if you have picture).
How to Navigate
When you press the “MENU” button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background).
How to Exit SDM
Use one of the following methods:
# Completely remove the power by removing the power plug.
Service Alignment Mode (SAM)
Purpose
# To perform (software) alignments.
# To change option settings.
# To easily identify the used software version.
# To view operation hours.
# To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: key in the code “062596” directly followed by the “INFO” button. After activating SAM with this method a service warning will appear on the screen, you can continue by pressing the red button on the RC.
How to Navigate
# In SAM, you can select the menu items with the “CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.
# With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
# With the “OK” key, it is possible to activate the selected action.
How to Exit SAM
Use one of the following methods:
# Press the “MENU” button on the RC-transmitter.
# Switch the set to STAND-BY via the RC-transmitter.
Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can call his dealer or the Customer Helpdesk. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode; therefore, modifications in this mode are not possible.
When in this chassis CSM is activated, a color bar test pattern will be visible for 5 seconds. This test pattern is generated by the Pacific3. So if you see this test pattern you can determine that the back end video chain (Pacific3, LVDS, and display) of the SSB is working. In case of a set with DFI panel, an extra test picture is generated. So you will see the Pacific3 test picture for 3 seconds and then the DFI EPLD test picture for another 3 seconds. With this extra test picture you can determine if the DFI board is working properly.
Also new in this chassis: when you activate CSM and there is a USB stick connected to the TV, the software will dump the
complete CSM content to the USB stick. The file (Csm.txt) will be saved in the root of your USB stick. This info can be handy if you do not have picture.
Another new item in this chassis is when CSM is activated, the complete error-buffer content will be shown via the blinking LED procedure.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user) menu on the screen!
How to Navigate
By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, you can navigate through the menus.
How to Exit CSM
Press “MENU” on the RC-transmitter.
