HOW TO TROUBLESHOOT AND REPAIR HV PROTECTOR/ TV GUARD 

in my next video you will also see how to turn HV guard into fridge guard, do you have an idea about it? let me know, leave a comment

Hello great video exactly what i was looking for and well explained. I have one that has stopped working, red light remains on and never goes to green. There are some resistors under the big capacitor but they are all burned and I do not know the values. Measuring with a meter ready various values from 409 Ohm to 470 Ohms but the first colour looks to be brown. Please could you tell me what value these should be? On an unrelated question. Ever since learning electronics I was told there should be a transformer to drop the voltage from 220v AC to the lower voltage. After passing the 4 diode brigde the 5.24V comes from 78L05 but where does the 12/24V DC to switch the relay come from?

A question of the day⚡do we have to use HV protector to protect a washing machine?? who watch this video also need to watch this👇 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q2oyEy30uxI.html

Any help

Main switches itself off randomly I don’t know why but it can be working then after some time in your switches itself off and it goes on the yellow late then after like 20 seconds again it switches on but I don’t know the cause of that

dear friend, i have also this type fridge guard with digital volt meter, i am using this guard approximately one year, before it shows me correct 220 volts in the meter, but now its showing 255 volts since 2 month.

I have a similar problem but mine when the relay switches it to green it immediately switches back to yellow

What can I do if the power supply to the relay reads 5.67V?

it is already operating with uncorrect 255 volts, there is no problem turning off itself , just showing uncorrect volts on the display.

We want to learn

How does the regulator work

We ni mtz bro?

Can tv , laptop , dstv be used on it at the same time ?
