Hisense TF21R08N repair the power supply of the TV that was struck by lightning

If you can't find the accessories of the original parameters, you can replace the Huamei universal power module, this universal power module works stably and reliably, I have replaced a lot of power supplies with it, and there will be no problems within three or five years. If you don't know how to use it, there are detailed instructions in the box, and you will know a little about maintenance.

If you change it like that, the power supply will not work normally, even if it can be at the time, but it will definitely not work for a long time. First of all, you can't replace the fast recovery diode with a normal diode. The ohm is the fuse resistor, and if you replace it with 180 ohms, the power will be insufficient.

The power supply starts frequently.

How big is your 3R9K, is the in5339 the same as the original parameters, make sure the power supply is okay, you check the wired signal channel, lightning high voltage through the wired damage to the signal channel. Thunderbolt broke our landline through broadband, I wish you success!

Thank you for your enthusiasm, because I didn't find the components of the original model, so I replaced the wrong model, the original resistance was replaced by 180 euros, I don't know if there is any impact? I don't know if it's okay? RM11C (fast recovery) is replaced by IN5399 (normal), I heard some people say that they need to change all, I don't know if they need to change all of them?

I don't know if there is a mistake in the component number and parameters you said, if it is correct, it should be your resistor changed to the wrong one: the previous one is the ohm resistor, you changed it to 180 ohms, check it carefully to see if it is wrong.

[FLY] Press and hold the menu button of the remote control for 5 seconds to return to the bus state[ FLY] Remote control shutdown exit using the user remote control CN-30501 Press the menu to select the sound menu''Volume''Enter the password 1147 to enter the bus [fly], remote control shutdown and exit [fly].

It's fixed, and it's out of the bus. Thank you for your reply, thank you Lotus Home Appliance Repair.

Is the landlord also a trainer?

Dear Hisense users, hello!

Press the menu button of the remote control--- select the factory mode--- factory options--- select the mother block to empty, I hope it can help you, I wish you a happy life.

Personally, I think that the sound of this TV horizontal bright line is good and sometimes bad:There may be leakage between the solder joints of the electric soldering plate,You wash the big board with banana water,See if there are solder joints touched together。

The field block serial number is soldered, or broken.

The power supply of the field output has virtual soldering, and it can be repaired again.

Virtual soldering! Didn't fix it before!

I haven't dismantled it,I think the repair shop can solve it,The TV thing is very troublesome,It turned out to be a master of a TV factory working,He looked at the circuit,He knew where there was a problem,Change a resistor to get it,You can ask Hisense to repair it,Just look at the data to solve the problem。

Try rewriting the bus data.

After testing, 0076 or 0076A remote control is used to add a - key in the lower right corner, which is the T1 button, press the mute button first, then press the T1 button, the screen displays M, press the super receiver to convert between M and WD, and press the T1 key to exit.
