 NOTES ON CHIP COMPONENT REPLACEMENT

Never reuse a disconnected chip component.
Notice that the minus (--) side of a Tantalum capacitor may be damaged by heat.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable.

The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts.
The flexible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

Before Repair and Adjustment:
Disconnect AC power, discharge Power Supply Capacitors C566~C569, C782 and C591 through a 10Ω, 5W resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid over current.  Current consumption at AC 120V, 60 Hz in NO SIGNAL mode should be ~650mA.

Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
• No sound is heard when the power is turned on.
• Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
If this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
Note : When the protection circuitry functions, the unit will not operate unless the power is first turned OFF and then ON again.

Power supply: AC 120 V, 60Hz

Always respect voltages. It makes sense to avoid exposure to electrical shock.  While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

These chassis are designed for Latin America (LA) markets ready for IPTV. The main chip is from Mstar and supports below features matrix.

All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage (100 ~ 240 VAC)
All voltages have to be measured with respect to ground, unless otherwise stated
All final tests have to be done on a complete set including LCD panel in a room with temperature of 25+or-7°C

The Picture Performance assessment such as White Balance (luminance and colour temperature) has to be performed into subdued lighted room after at least 45min of warm-up in order to avoid any temperature drift influence (colorimetry vs time)

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 spec. The error should less than 5%. 

For example, the voltage for main chip (+3V3, AV3.3, +1V2, CORE1V, etc.), the voltage for DDR (DDRV), the voltage for amplifier (AMP-VCC), etc...

Project ID Modification
There are different ID stored into the NVM depending on different Panels settings and Models features, but there’s only one key branching Project ID that includes all. So, it’s not recommended to modify Panel ID with Hyper terminal as other ID features may not change.
To modify Project ID, you need to go through “Design menu Service menu Project ID”, then spin left or right with RCU “Zoom±” keys to suitable ID (Project name is dynamically refreshed).
