neon Tube power supply faulty T8006G V3.0

[bohaboha]

Hi everyone needs your help with this Neon Tube power supply
Here are some pictures
Large capacitor has 320V but then nothing.has removed some parts but is not sure that they are bad except that they sounded bad on the circuit

Re: neon Tube power supply faulty T8006G V3.0

Check these low-resistance resistors, if they are open, change transistors, diodes, the green capacitor is in order.

Re: neon Tube power supply faulty T8006G V3.0

have tested them six resistors in the row below and after the capacitor, but no reading at all has lifted one side on all I must know their value
first

Re: neon Tube power supply faulty T8006G V3.0

maybe because it's really low value that my multimeter can't read

On them, black dots are burnout, they burned out.

Re: neon Tube power supply faulty T8006G V3.0

Very observant. How can I measure them? Have not managed to read current values on the fuse but good on large capacitor

Re: neon Tube power supply faulty T8006G V3.0

How can I measure them?

A strange question, take a multimeter, set a resistance measurement of 200 Om on it and measure the resistance on these resistors.

Re: neon Tube power supply faulty T8006G V3.0

I have done so but no reading at all because I wonder how to do it

Re: neon Tube power supply faulty T8006G V3.0

Well, it means they are in the cliff, burned out.

Re: neon Tube power supply faulty T8006G V3.0

Sure but all it is a bit strange then must be some other component that causes maybe the transistors or some of the capacitor around therefore the first blue diode is not good either

[lotas]

Re: neon Tube power supply faulty T8006G V3.0

The resistors burned out because the transistors burned out, the blue diode is not a diode, it's a dinistor, you can't just check it and it very rarely burns out in this circuit.

Re: neon Tube power supply faulty T8006G V3.0

That explains everything. so it is called Denistor it is denoted by "D" thought it was diode, it should be measured as Diode or?then I have to find two transistors or some equivalent otherwise it will not be quickly repaired + I have another that is broken but it is a bit different
