LG32LB1R TV: Identifying Zener Diodes ZD402 & ZD404 for YP2632T Power Board Replacement

Question

I spoiled my power for YP2632T. Destroyed znenerové diodes that ZD402 and ZD404 can not be read. Can anyone tell me what the diodes are? Thank you

The ZD404 diode is what?

lisek · Answer

Well look at applications FAN7601. (IC302 / 304) * FAN7601, LAF0001) - you can pre-draw this part of the layout on a piece of paper + pencil to see what pin.IC304 can it be? Zener diode connected

aadam07 · Answer

I exchanged the IC302. ZD404 is burned only. I apologize for my Polish, I Slovak.

But you ... you're licking the fox. You would at least have the trouble to check where the LEDs are instead of writing idiot not on the subject!

Malek · Answer

So what did this post bring to solve the problem? Lisek has a lot of knowledge in the subject and tries to help everyone without hitting points with haunted, empty posts.
Mirex, if you have nothing specific to write, sit down and sit on d ... e

I looked at the photo.autora and red rims ... the rest went like a piece of cake with butter ?! And the truth is hidden

mirex · Answer

Well, show it now. I would take a fairly familiar model of this manufacturer for comparison. Maybe something would come up. These are the effects when borrowing pictures from other fors, but they do not describe them humanly and do not provide links. You have the same way. Copy what you can, without thinking in general.

I see that my last post has glided into space, so I will repeat: Read on the Forum about Lgp32-Atn-Power Supply Yuyang Telecom.

mirex · Answer

Because you're totally out. That's why I reported. But the attachment itself, not the content of the whole post. Admin knows better, so do not discuss. Recently, the file from STR-W6053 has been added to the forum once again. Take a look at it and check it out. Especially when you loaded yourself once. Why the hell? Find out what is the wanted diode ZD404 ?? Do not overdo it! The correct hint is analyze the LGP32 ATN scheme and compare it with your motherboard. Maybe you can deduce what parameters the diode should have.

lisek · Answer

With your lips you took it out that is, I had to change the keyboard in the meantime, so you were faster. (' ') (' ')

aadam07 · Answer

I preanalizoval scheme Lgp32-Atn-Power Supply, but I am not mudra. It could probably be a Zener diode to 6V, but I'm not sure.

mirex · Answer

Then draw us where this LED is on. Just.

aadam07 · Answer

At the top is marked with an arrow ZD404.

mirex · Answer

We know where it is on the record!
We want to know where it is in the electronic system.
Please make a freehand drawing (diagram) of this piece of power supply.

If you can not think of a model based on the LGP32 scheme, then maybe we will succeed.

Or maybe there is no similar solution there and you have to move your head.

So a pencil, a card and to work. Exactly - where the cathode, where the anode plus all the elements associated with it. If it has any connection to the transistor, then what does this transistor do next.

aadam07 · Answer

Thank you for your help. The diode is Y13, essentially 36V.
