Ok, thanks for the tip, I'll give it a try.

Re: Samsung LE32S81B - missing standby voltage
That was my first plan, if you read my first entry it will be clear to you. But apparently I was stupid and went to look for the eeprom on the power board instead of the main one. It's my school and it looks like I had the wrong version, mine was with legs, and that's where the smd version goes....Leave a comment:

Re: Samsung LE32S81B - missing standby voltage
Yes, the volume is more than 300 and when you go to reduce it to 301 it is like 1 and when you go to 299 it is again at max then at 201 it is like 1 at 199 it is again max and so on until you reach the normal scale 1-100 but this trace remains on the screen and is not deleted.Leave a comment:

Re: Samsung LE32S81B - missing standby voltage
I finally got the diode, replaced it and the TV works, satisfied.
But my main problem that caused me to disassemble the TV is still there. When it turns on, it is amplified to max. more precisely at 300 and when you go to reduce the volume, a line remains on the screen as seen in the photo.
In addition, I also replaced all capacitors, one was bad.
Has anyone had a similar problem?...Leave a comment:

I'm bad with labeling these things, if you can help me, I took a better photo?...Leave a comment:

Re: Samsung LE32S81B - missing standby voltage
I found a short circuit (marked in red on the diagram) it is DZB801 30Vz SOT23
After I connected the voltage to the board, I got stand by voltage.
I'm wondering if that diode is there only in terms of protection, will it work without it?
Ako je trebam zamjeniti kako da nađem oznaku?...Leave a comment:

Samsung LE32S81B - missing standby voltage
Good day, instead of [URL="https://dalincom.ru/datasheet/FSQ0165R.pdf"]Q0165R[/URL] I mistakenly put [URL="https://www.onsemi.com/pdf/datasheet/cat24c256-d.pdf"]24C256[/URL] (don't ask me how) and made a short circuit. After I put Q0165R I don't have stand by voltage again. There is no voltage on the cold side. I found the schematic.
I checked a few things but didn't find anything. When I checked the DB802 diode, it showed a short circuit, but when I unsoldered one leg, it looked fine, and I still have a short circuit on its contacts. On the other side of the... -
