Audio amplifier stage with TPA3113(U168)
17MB62 uses a 6W Class D Mono Audio Amplifers for from 26” to 32” TVs. The TPA3113D2 is a 6-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements.  SpeakerGuard™ speaker protection circuitry includes an adjustable power limiter and a DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage rail lower than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs.  The TPA3113D2 can drive stereo speakers as low as 4 Ω. The high efficiency of the TPA3113D2, 87%, eliminates the need for an external heat sink when playing music.  The outputs are also fully protected against shorts to GND, VCC, and output-to-output.

POWER STAGE
The DC voltages required at various parts of the chassis and panel are provided by a main power supply unit. MB62 chassis can operate with IPS60, IPS16, IPS17, PW26, PW27 as main power supply and also with 12V adaptor.  CN706 is used for IPS60, IPS16 and IPS17 and CN1 is used for PW26 and PW27 JK9 is used for the adapter option and also CN75 inverter socket or DB32 chassis with CN709 is used to supply backlight.
The power supplies generate 18,12,5,3.3 and 12,5 volsts standy mode DC voltages.  Power stage which in ON Chassis generates 5,3.3 standby voltes and 12,8,5,3.3,2.5,1.8 and 1.2 volts supplies for other different parts of the chassis.
No Backlight Problem
If TV is working, led is normal and there is no picture and backlight on the panel.  Possible causes: Backlight pin, dimming pin, backlight supply, stby on/off pin Backlight pin should be high in open position. If it is low, please check Q181 and panel cables.
Dimming pin should be high or square wave in open position. If it is low, please check S16 for Mstar side and panel or power cables, connectors.
Back-light power supply should be in panel specs. Check CN705 for MB62, related connectors for power supply cards.
Led Blinking Problem
LED blinking, no other operation
This problem indicates a short on Vcc voltages. Protect pin should be logic high while normal operation. When there is a short circuit protect pin will be logic low. If you detect logic low on protect pin, unplug the TV set and control voltage points with a multimeter to
find the shorted voltage to ground.
No Sound Problem
No audio at main TV speaker outputs.
Check supply voltages of VDD_AUDIO, 5V_VCC and 3V3_VCC with a voltage-meter.  There may be a problem in headphone connector or headphone detect circuit (when headphone is connected, speakers are automatically muted). Measure voltage at HP_DETECT pin, it should be 3.3v.
No Sound Problem at Headphone
Check HP detect pin, when headphone is. Check 5V_VCC and 3V3_VCC with a voltemeter.
Standby On/Off Problem
Device cannot boot, TV hangs in standby mode.
Check HP detect pin, when headphone is connected. Check 5V_VCC and 3V3_VCC with a voltage meter.
Standby On/Off Problem
Device cannot boot, TV hangs in standby mode.
There may be a problem about power supply. Check 12V_VCC, 5V_VCC and 3V3_VCC with ith a voltage-meter. Also there may be a problem about SW. Try to update TV with latest SW.
It is good to check SW printout via hyper terminal [or Teraterm].  These printouts may give a clue about the problem.
No Signal Problem
Check tuner supply voltage; 3V3_TUN. Check tuner options are correctly set in Service menu. Check AGC voltage at IF_AGC pin of tuner.
