CV512H-U 42 after-sales support and maintenance manual
CV512H- U42 is a power supply, constant current driver, one of the TV boards, may receive a PAL /
SECAM standard analog television signal, for European (including UK) and other
markets. CV512H-U42 used in high efficiency switching power supply, matching backlight
power 45 W or less, typically a voltage value matching the backlight 45 V ~ 100V, dual backlight
parallel output, -42 inch to 32-inch LED backlight screen.
1. the safety instructions:
1.1 replacement, any welding components when the dial plug and cable, power supply must be
OFF.
a) BULK capacitor needs to discharge
b) can not be touched once after power on
1.2 anti-static measures (the entire production process must be anti-static!)
a) can not easily touch the IC;
b) an anti-static iron;
c) welder must wear anti-static gloves.
1.3 replacement of components that have special safety requirements, reference list should not be
free to change specifications and models.
1.4 Test and verify the board must use the matching accessories (power board, keypad, etc.), if you
use other accessories need to carefully confirm the correctness of the connection.
1.5 board storage, the use of temperature and humidity are as follows, be sure to strictly follow
the implementation:
Storage temperature / humidity: -40 ~ + 85 ℃ <= 95%.
Temperature / humidity: - 1 0 + 60 ℃. <= 95%
Note: Observe the safety instructions as described above when servicing this motherboard.
2. the main function:
1. Supports SD and HD resolutions (480P / 576i / 720p / 1080i / 1080P);
2. Low standby power (≤ 0.5 W)

5. Support USB software upgrade;
3. the basic working principle:
(1) analog signal flow:
Signal received by the antenna into the TUNER (UT1, RDA5160; U27, RDA5815), SOC
(U7 S2T512) by the TUNER I2C control, frequency selection, setting IF bandwidth, the amplitude of
the intermediate frequency signal is provided. TUNER output IF signal into the SOC internal
demodulation and decoding, and ultimately converted into video and audio signal display.

TPS563201 TI is smaller DC-DC power devices, SOT23- 6 package, the chip has the following main
characteristics:
Input voltage range: 4.5V - 17V
Output Voltage Range: 0.768V - 7V
TPS56X201 is a series of common materials, which number represents the X device can
support a maximum average current
Cycle-by-cycle current protection
A typical soft-start time 1mS
Hiccup mode overcurrent protection
Non-latching undervoltage and overtemperature shutdown protection
Through the TPS563201 features, we need to pay attention to the maintenance of the following:
Although it is a series of devices, as recommended by the replacement of BOM item
number, if you really need to use when high-profile replacement, it is recommended to replace the
use of adjacent specifications, in order to avoid circuit operates at light load mode, resulting in
excessive ripple at the time of replacement.
When output short circuit or overcurrent, the circuit will hiccup mode (typically 15mS) in
the form of work.
In the internal OVP circuit, the output will be limited to 7V, which requires special attention,
because in the re-welding process, the FB may pull the resistor short-circuit or pull-down resistor,
so that the circuit output will be limited to 7V, for the current 5V systems, will be able to make the
whole system work, but this is a wrong mode of operation. Recommended after welding need to
confirm the correctness of the output of 5V.
Undervoltage and thermal shutdown are non-latched, that is to say in the removal of these
failures, the circuit can automatically return to the normal state (do not restart the state).

RDA5160 is a support global analog and digital terrestrial and cable tuning standard IC, generally
works as follows:
Digital and analog signal RF head (CNT1 is) passing through the filter capacitance and
inductance coupling, RDA5160 into the LNA (low noise amplifier) amplifies.
The SOC selected frequency (LO) via I2C control RDA5160, disposed IF bandwidth.
SOC control by controlling the amplitude of the IF AGC, and this point should be noted that:
AGC vary during the station search, the search platform will be completed at a fixed value, but this
time the amplitude of the intermediate frequency internal RDA5160 is adjustable.
RDA5160 internal block diagram as follows:
Input frequency range: 42 MHz-1002MHz
IF may be set 6MHZ, 7MHz, 8MHz
Built-in 1.8V LDO, to note that the built-in 1.8V output requires software to control output.
I2C can configure multiple addresses.
The main features of the chip are as follows:

RDA5815 is a support for the global digital satellite signal tuning IC, the general work process is as
follows:
Digital and analog signals through the RF head (J2), after capacitive coupling filter, into the
RDA5815 LNA (low noise amplifier) to enlarge.
SOC through the I2C control RDA5815 frequency selection.
SOC through the AGC control control the amplitude of the frequency, which need to be
noted that: AGC in the search process will change, after the completion of the search station will
be fixed at a value, and this time the amplitude is RDA5815 internal adjustment.
RDA5 815 internal block diagram is as follows:
