TCL and Thomson - L32B2810/MT31BP-AP – Alignment procedure - how to upgrades the software – detailed description
Alignment
Procedure - MM31BP Series
These chassis
are designed for European LCD TV markets with MPEG4 for both TCL/THOMSON
brands. The main chip is from Mediatek (MT5531 series)
MT5531 FLASH
Size and Key Blocks Location’s Assignment – MT31BP-AP (V0 91).DOCX
To
communicate with the TV product for debugging, adjustments and so, it is
required suitable 0-5V serial Interface like in the following picture
Pre-Conditions
and DC/DC Check
Before power
on, please check the board according to the relevant block diagram and circuit
diagram, and make sure that no serious issue or mistake can destroy the board.
For example, the output of DC/DC and LDO should not be shorted to ground.
Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram, circuit diagram and voltage specification within 5% margin.
For example, check SoC voltage (AV3V3, VCCK-1V2, etc.), DDR voltage (DDRV) , amplifier voltage (Main_Power), etc… Only the standby voltage is necessary if there is no software in the flash.

To manage quicker mass reflashing, a predefined OAD DVB-T channel (freq:850MHz
/ bandwidth:8MHz) is embedded to SW core and only available into Factory mode.
Some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe', dsmmerge.exe, …) from Intellbyte Inc. http://www.intellibyte.com/ might be
necessary to create appropriate DVB SSU TS. Over some predefine settings such
as repeated datablock insertion, null packets size, … (controllable in configuration
file), here below are mandatory OUI entries structure to prepare DSM-CC
carousel image format:
[SW Entry are referring to following PKG image file name “V8-0MT310x-LF1Vyyy.pkg”
See enclosed necessary Data Broadcast Carousel configuration file format details (DBC)]
To build an
OAD TS, it’s necessary to create a temporary common and interchangeable DSM
file format using below command and arguments:
‘bin2dsm.exe -v -v -v -m0,0,"TCL_HW5881",0 -n200 -z102400 -nz -o%FILE%.dsm -h"OUI=CUST_OAD_OUI
model=CUST_OAD_HW_MODEL version=CUST_OAD_HW_VERSION vm=0xffff" -s"OUI=CUST_OAD_OUI
model=CUST_OAD_SW_MODEL version=CUST_OAD_SW_VERSION vm=0xffff" %FILE%.pkg’
Then, OAD TS can be completed using below command and arguments:
‘dsmsectn.exe -v -dvbssu -mpegts -patpmt -nit_ter -sdt -o%FILE%.ts -gTCL_HW5881.dbc %FILE%.dsm’
For more robustness, TS can be played with following presets such as modulation:QAM-64, guard interval:1/8, coding rate:2/3 to ensure ~22Mbps.
OAD reflashing process is managed within 4 steps operation: multiplex detection, DVB transfer, flashing and warm-start.

UART & IR
Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with its VGA port well connected to suitable UART device or an IR emitter device correctly facing up TV (see below “Product Assembly - section 2.0”
How to activate “Factory key”).
The SoC’s RS232 mode is automatically enabled at power-on and doesn’t require any command initialization frame. <0x30 0x30 0x30 0x2E 0x30 0x65 0x30 0x74 0x30 0x0D 0xE2> from host to TV.
So correctly setup UART parser engine for further serial communication, it’s necessary to send following command frame <0xAA 0x06 0x10 0x01 0xA7 0xEF> within following COM presets 115200/8/n/1; “PS” caption might be toggled and displayed on bottom left screen (“S” like Serial) if successful.
To communicate with TV depending on SIACP revision layout implementation, you may need to fulfill UART/IR commands protocol and format described on enclosed SIACP requirements document.

Project ID Modification
There are different IDs stored into system memory depending on different Panels settings and Models features, but there’s only one key branching ProjectID that includes all. So, it’s not recommended to modify PaneID with
Hyper terminal as other ID features may not change.
To modify ProjectID, you need to go through “Factory menu - Other - Project info - Project ID”, then spin left or right with RCU “◄/►” key” keys to suitable ID (Project name is dynamically refreshed).
Below is none exhaustive Project ID table for reference. Project list and all relative information are dispatched and updated as a new firmware package is released.

Philips 26LL590121- CRT TV, Service mode and adjustments, convergence adjustments, How to test an opto-isolator, How to check a programmable regulator IC and more....
Common to all models of Philips large screen CRT TV sets 0n F8 Chassis
POWER SUPPLY DESCRIPTIONThe F8 chassis family uses a free-running switch-mode power supply with a single controller IC. As AC power is applied to the set, approximately 160volts DC is developed by the bridge rectifiers and fed to the primary winding of the power transformer, then to the FET switch. The start voltage for the power supply is taken from the hot leg of the AC input. This voltage goes to controller IC 7520. A separate operating voltage is developed from the power transformer, rectified, and applied to IC 7520. The power supply is on all the time; there is no standby mode. The set is turned on and off by the microprocessor switching the +8 volt regulator on and off. The +8 volt is the supply voltage for the signal processor.
IC7520 is regulated by means of a feedback circuit, monitoring the +11 volt secondary line. Any voltage variations are reflected back to the controller IC 7520 through an Opto-Coupler IC and change the operating frequency of the power supply as needed. REMEMBER TO USE AN ISOLATION TRANSFORMER WHEN SERVICING THIS CHASSIS.
Complete Circuit Description
When AC is applied, current flow through the Bridge Rectifier circuit causes two simultaneous events to occur:
1. Capacitor 2508 begins to charge to 160 volts DC.
2. Capacitor 2540 begins to charge to 14.5 volts DC.
When capacitor 2508 is fully charged, 160 volts is applied to the drain of 7518, through transformer 5545. When capacitor 2540 is fully charged, 14.5 volts is applied to pin 1 of 7520. This voltage will cause 7520 to begin oscillating and putting out a pulse train on pin 3. These pulses will cause 7518 to conduct which will cause a field to build up in the primary winding of transformer 5545. When this field collapses, a field will be induced in the secondary windings. Pins 8 and 9 of 5545 will output to diode 6540, which will rectify the pulses. Capacitor 2540 will filter the pulses and provide approximately 12.5 volts to pin 1 of 7520. This now becomes the RUN voltage for 7520.
Feedback control is accomplished by monitoring the 140 volt line. The 140 volt, +VBATT supply is sent through resistor 3571 to pin 3 of the Programmable Regulator IC, 7570. This regulator will turn on at 2.5 volts DC. Current will then begin to flow through the diode portion of the Opto-Isolator IC, 7581. The intensity of light caused by this current flow will then control the conduction of the transistor portion of 7581. The voltage appearing on pin 4 of 7581 is then monitored by pin 14 of 7520 where it is compared to a 2.5 volt reference voltage. Changes felt on pin 14 will control the width of the pulses coming out of pin 3. These pulse changes will determine the “on” time of 7518
F8 CHASSIS INTRODUCTION
The F8 chassis is a leader TV chassis produced by Philips Consumer Electronics Company for the 1999 model year. The F8 chassis is used in sets with 25“ and 27“ screen sizes. The F8 chassis is a global design and is oriented front to rear, or ”north to south“, as it has been called. The F8 chassis tuning system features 181 channels with on-screen display (OSD). The main tuning system uses a tuner, a microcomputer IC, and a memory IC mounted on the main chassis. The microcomputer communicates with the memory IC, the customer keyboard, remote receiver, U/V tuner, signal processor IC and the audio output IC via the I2C bus. The memory IC retains the settings for favorite stations, customer-preferred settings, and service/factory data.
The F8 chassis uses a Very Large Scale (VLSI) Integrated Circuit for signal processing. This IC performs video IF, sound IF processing, AGC control, horizontal and vertical drive and synchronization, also luminance/chrominance processing. The on-screen graphics and closed caption decoding are done within the microprocessor, and then sent to the signal processor IC to be added to the main signal.
The F8 chassis utilizes a switch mode power supply for the main voltage source. The chassis has a hot chassis ground reference on the primary side of the power supply, and a cold ground reference on the secondary side of the power supply and the rest of the chassis. ALWAYS USE AN ISOLATION TRANSFORMER WHEN SERVICING THIS CHASSIS FOR YOUR SAFETY.
Vertical Circuit
The vertical drive signals are internally generated in IC7250 and are output on pins 46 and 47. From there they are sent to the Vertical Output IC, 7401, pins 1 and 7.
Inside the IC, the waveforms are amplified, shaped and output on pins 5 and 6. The output on pin 5 is the waveform that drives the yoke and provides feedback to the IC.
The output on pin 6 is the Vertical Synchronization pulse that is sent to pin 37 of the microprocessor.
Horizontal Circuit
The horizontal drive pulse is internally generated in IC7250 and is output on pin 40.
This pulse is amplified by transistor 7461 and transformer coupled by 5461 to the base of the Horizontal Output, 7460, where it is amplified.
Shaping takes place in the collector circuit (C2463 and C2465), which results in a perfectly timed 825 volt peak-to-peak pulse to drive the deflection yoke and the flyback transformer.
The Flyback Transformer secondary windings produce 10 working voltages:
VlotAux-11V, VlotAux+11V and VlotAux+50V all supply power to the vertical output IC, 7401.
The 187 volt VideoSupply, the filament voltage, Screen voltage (VG2) and Focus voltage all go to the CRT board.
The EHT voltage goes to the anode connection on the CRT.
The VT_Supply and the VlotAux+5V Supply both go to the Tuner. The VT_Supply is zenered down to 33 volts for tuning voltage and the VlotAux+5V supply acts as B+ for the Tuner and also becomes the +5 volt supply. The VlotAux+5V supply also provides voltage to the Audio Circuits.
Shutdown Circuits
Three of the shutdown protection circuits are derived from pins 7 and 10 of the Flyback Transformer.
If the voltage on the filament line (pin 7) goes too low, transistor 7482 will turn on and apply a positive voltage to the P9StbyOn+Protn line.
If the voltage on the filament line (pin 7) goes too high, transistor 7462 will turn on causing transistor 7463 to turn on and apply a positive voltage to the HEW_Protn line.
If the beam current (pin 10) becomes excessive, the voltage on the EHT line will go toward the negative direction. This action will cause transistor 7481 to turn on and place a positive voltage on the P9StbyOn+Protn line.
For sets having East West correction circuitry, pin 10 of 5545 is being monitored by transistor 7470. Transistors 7470, 7481 and 7482 all control transistor 7605. In the event of a problem, 7605 will bring pin 16 of the Microprocessor, 7600 low, shutting the set down.
How to Check an Opto-Isolator
Procedure
Using a basic diagram taken from the F8 schematic, we are going to determine whether or not IC7581 is functioning properly.
Step -1
Apply the positive lead of a variable DC power supply to the positive terminal of capacitor 2561. Connect the negative lead of the power supply to pin 1 of IC7570. By connecting them this way we are able to use resistors 3685 and 3575 as protection for IC7570.
Step -2
Apply the positive lead of an ohm meter to pin 5 and the negative lead to pin 4 of 7581. Set the ohmmeter to the 2K scale or greater.
Step -3
Slowly increase the DC voltage from 0 to 5 volts. If the IC is good, you will see the reading on the ohmmeter start decreasing as the voltage approaches 5 volts.
CAUTION: Do not exceed 5 volts DC.
How to Check a Programmable Regulator IC
Procedure
Using a basic diagram taken from the F8 schematic, we are going to determine whether or not IC7570 is functioning properly.
Step -1
Apply the positive lead of a variable DC power supply to pin 3 of IC7570 and the negative lead to cold (chassis) ground.
Step -2
Apply the positive lead of your DVM to pin 1 of IC7570 and the negative lead to cold ground.
Step #3-
Slowly increase the DC voltage from 0 to 2.5 volts. If the IC is good, you will begin to see a DC voltage reading on your DVM as soon as the applied DC voltage is 2.5 volts.
