Haier 25t6d a td power supply 10B voltage is how many volts

Is it a color TV that needs to be repaired or what? This problem needs to be dealt with by a professional for you, it is recommended to find Haier after-sales service, the general situation is 140 volts to 145 volts, so it will be more dangerous to deal with it yourself, Haier after-sales service is good, and professional, find them, after all, it is a Fortune 500 company, and after-sales service is a benchmark in the industry.

Let's put it this way:Last year, I also had my own color TV high-voltage package leakage ignition,Damaged,To be replaced,And this color TV was purchased for ten years,I can't buy the original high-voltage package at all,I know by checking the information,As long as the new one is purchased,Same as the old foot pass、The foot voltage value is the same、The foot arrangement is the same。 In addition, when I went to buy, I happened to be in the electrical accessories store their high-voltage package reference book, I asked the boss, he helped with a suitable high-voltage package, I installed and used it for a year and a half, normal.

The 25-inch color TV can be interchangeable with the 29-inch high-voltage package.

Ask Haier's customer service, and they will know for sure.

I can ask Haier customer service to give you an answer.

There are so many people who use Haier's products.

I think my Haier TV has been available for seven or eight years.

The voltage of this model is certainly the same as the others.

I don't understand this, so I'd better ask Haier customer service.

Ah, I really don't know, sorry.

Consult Haier's customer service, don't worry.

Isn't this the same as any other appliance?

It's usually the same voltage, and nothing else.

You're going to ask if this is going to be changed or what?

I don't know much about these voltages.

Find after-sales, or ask customer service.

Is it to change the power supply or whatever.

9656 power block 1 pin 260 volts, 2, 3, 5 pin 0 volts, 4 over 13 volts, no output voltage, power block is broken? Xiao Di Pi is a novice and has no information on how to fix it, so thank you for burying it first.

**)The 25TA-S power supply circuit is a typical self-excited pulse width modulated switching power supply. The main circuit structure is a step-down type, which is a cold core power supply, and the circuit is mainly composed of switch tube V513, excitation tube V512, switch transformer T511, rectifier filter circuit, etc. The AC220V power supply voltage is rectified by a bridge composed of VD503 VD656 and C503 C506 and smoothed filtering by C507 to obtain a DC voltage of about 300V, which is added to the collector of the switch V513.

V513 and the primary group 3-7 and feedback winding 1-2 of the switching transformer T511 form a self-excited intermittent oscillator, which generates an intermittent oscillation pulse of about 560V(P-P) at the collector of V513, and its pulse width is controlled by the excitation capacitor C514. The V512 collector and emitter are connected between the base and emitter of the switch V513, and the conduction state of V512, that is, the current flowing through V512, can control the on-time of V513, the current flowing through V512 is large, and the on-time of V513 is short and the voltage is low; The current flowing through V512 decreases, that is, the shunt effect decreases, and the on-time of V513 increases, and the voltage increases. The working state of V512 is controlled by the control circuit composed of V563, VD561 and N501. The control circuit adopts direct sampling, and the optocoupler transmits error information.

The V506 is an error comparison amplifier, and the N501 transmits error information. The error information changes the current flowing through N501, and the change produces an error voltage on the resistor R511, which controls the conduction state of V512, thereby changing the length of the conduction time of V513 and achieving the purpose of width adjustment. When the output DC voltage B1-130 volts increases, the V553 current increases, and the V511 current increases through the photocoupler coupling, the V513 on-time is shortened, and the output voltage decreases to achieve the purpose of voltage stabilization, and vice versa.

1) The pulse voltage output by the secondary [10] pin of the switching transformer T511 is rectified by VD552, C552 and C562 filtered and outputs 190V voltage as the power supply of the video amplifier circuit circuit;

2) The pulse voltage output by the secondary [9] pin is output by VD551, C551 rectification, and C561 filtering output 130V voltage as the main circuit power supply;

3) The pulse voltage output by the secondary [11] pin is rectified by VD553 and filtered by C563, and the output voltage of 24V is used as the power supply of the field scanning block N451 after V551 is adjusted;

4) The pulse voltage output by the secondary [12] pin is rectified by VD554, C554 and filtered by C564, and 15V is output as a small signal power supply, and +5V voltage is obtained by N553 voltage regulation for CPU and control circuit, after V554 adjustment, N551 voltage is stabilized and output 12V voltage as high-frequency tuning and other circuit power supply, and then 5V voltage is output as N201 chip power supply by N552 voltage regulation;

5) The pulse voltage output by the secondary [14] pin is rectified by VD555 and filtered by C565, and the current limiting output voltage of R562 is 20V as the power supply of N301 and N302 power amplifier blocks.

You swapped out the resistor at the e-pole.

The Haier 25T6D-TD power supply is STR-F6656

Drawings of the power supply part of the machine:

Call 4006-999-999 headquarters** and ask the after-sales engineer to know.

Hello! Generally, the voltage of a laptop is about 19V, and the power consumption mainly depends on the configuration, and you can find the parameters you need on the power adapter

Yes, yes, that's fine, but let's not talk about voltage, we should say what the peak power is.

Haier 25T5D a T, +B voltage is only 80 volts.

Disconnect the power supply, put the positive and negative poles of the filter capacitor C563 on the street after +B rectification, test +b again, and change the high-voltage package if +B is normal.
