What's the voltage of this zener diode ?

Guys,

What's the voltage of this zener diode ?
I took some pictures, I can see J62 ?? I'm not sure...so small...
Please have a look,

Cheers

Looks like similar with this one...:

but not sure...

anyone knows ?

Is it bad? How is it figured out to be ZENER Diode? More details needed. You can also can test what the Zener Voltage is by searching how to test Zener diode.

Ok, I can find the cut off voltage with testing it ? diode DMM test ? or ?

Or the easy way is to search the net:'how to test a zener diode with a digital multimeter'
So is it shorted out?

Re: What's the voltage of this zener diode ?

Ok thanks...the power supply must be higher than the zener and 1K resistor...ok...I'll find some in my box...

Where is it used in the circuit?

[bianchi77]

Re: What's the voltage of this zener diode ?

I tried with 18V but the meter it's equal to 18V so the zener voltage is more than 18V isn't it ??...

Re: What's the voltage of this zener diode ?

Well, how does it tested out using diode mode on the meter, that would have been my first test, and where is it used in the circuit?

Re: What's the voltage of this zener diode ?

It's 0.7V on diode test DMM....It's located on secondary side of switching power supply...could be 26V for its cut off ? from the symbol I saw on it ?

Re: What's the voltage of this zener diode ?

It's 0.6V on diode test DMM....It's located on secondary side of switching power supply...could be 26V for its cut off ? from the symbol I saw on it ?

Need the Pictures of the top and bottom side of the board where this diode is locate, and the pictures of the whole top and bottom side of the board so we can tell how this diode is being used.

Re: What's the voltage of this zener diode ?

Ok, I'll take picture and post soon...cheers

Here's the photo from the zener diode location

Toshiba TV?
What is the model number of this TV?
Pictures of the whole board?
It looks like it is connected to the IC, cannot tell much, no pictures of the bottom side.
The more details we have the better.
Did you remove lots of parts form the board?
BTW, it looks like there are two diodes in parallel, pictures are too blur.

Re: What's the voltage of this zener diode ?

Yes there's diode next to it ..yup I removed them all...my friend gave me the board as a part....

[bianchi77]

Re: What's the voltage of this zener diode ?

Not a problem, I'll take the picture, I have no idea what the model number of this TV...
