How much is Haier color TV 21TA1 T

Hello, thank you for asking the company.

Hello, this model of TV has been discontinued, thank you for your attention to Haier TV.

You are welcome to ask the company questions again.

We wish you a happy work life

Landlord, this model is a later CRT product, there should be a lot of matching picture tubes, and the movement may have been replaced, so now it is more difficult to say which high-voltage package to use.

First of all, it is recommended that the landlord directly change the TV,If the landlord really wants to know and wants to repair it,It is recommended that you first see which movement is the product (the main chip model on the motherboard),Then say which picture tube (Beijing Panasonic or Huaying or other?) Maybe someone will be able to help you.

This phenomenon is the action of the protection circuit, you can first disconnect the circuit and connect the 60W fake load to see if the power supply is still protected? If you still protect, start to check the power supply, if you don't protect, you can check the circuit of the field can be disconnected one by one to judge the voltage, thank you.

You first follow the operation of the station netizens, if not, it is recommended that you let the after-sales service come to help you repair it.

Protected or short circuited.

Check whether the large switch feet have corresponding high and low level changes. No, you can try a new data.

First measure the voltage of each pole of the line push tube to know whether the line is started.
