TP.VA56.PA671 LCD TV combo board is outputting 12 volts properly from SMPS, but the power indicator light is not flashing. TV does not turn on when trying to turn it on by remote or key. In this situation, in some cases, by checking all the voltages of the TP.V56-PA671 circuit board, it can be seen that there is no voltage supply problem, but the TV is not working. In a word, all semiconductor devices and pre-regulator ICs and transistors on the circuit board of the TV are working correctly, but the power light is not turning on.

This kind of problem can occur not only in the TP.V56.PA671 combo board, but in any brand of main board, and to know why such a problem arises, one must have explicit knowledge about the operating system of an LCD TV.

The motherboard of an LCD TV is precisely like a computer. This board contains input and output devices like a computer. The LCD TV display is the output device. The LCD TV remote and switchboard work like a computer keyboard.

The LCD TV includes a processor, RAM, and graphics processor. The 25Q32CSIG memory IC works as RAM, with a storage capacity of 32 kilobytes. The TSUMV56RUU-Z1 IC contains the processor that controls the LCD TV's operating system. Moreover, the TSUMV56RUU-Z1 IC controls the graphics T-Con processor.

Now, let's come to the real point. The main topic of this article is the power supply of the TP.VA56.PA671 LCD TV board is fine, but the power indicator light is not flashing, and the TV does not turn on when you try to turn it on. Now, we try to understand why such problems occur.

TSUMV56RUU-Z1 processor IC is a component of digital electronics. Its function is signal processing and system control. A 24 MHz clock signal controls the input and output signals and voltages of this IC.

TP.V56.PA671 LCD TV Combo Board No Power Solution

(You can watch this VIDEO to solve the no-power problem of TP.VA56.PA671 LED TV Board)

The power indicator light is connected to the TP.V56.PA671 LCD TV motherboard does not flash due to various reasons. First, check the 12 supply on the board. Then, if the voltages shown in the image below are incorrect, the pre-regulator IC and transistor may be damaged.

The TP.VA56.PA671 board contains a 24 MHz SMD (Surface Mount Device) crystal oscillator to generate the constant clock signal. Two terminals of this crystal oscillator are connected to the ground with two 18pF capacitors.

Standby Voltage of TP.V56.PA671 LCD TV Mainboard

Both capacitors are sometimes damaged or shorted, resulting in the circuit stopping to produce the clock signal or changing the clock frequency. If this happens, the LCD TV's power indicator light will not flash, and the TV will not turn on. In this case, changing the two 18pF capacitors can solve the problem of the LCD TV's power indicator light not flashing.
