Damaged Manta LED1905 TV: Incorrect 24V Connection - Seeking Service Chart & Part Identification

Question

Hello Dear Users. As in the subject of broken TV Manta Led1905 - brother-in-law mistakenly connected it in tira under 24v. Unfortunately, I did not find the service chart and identification of the parts is difficult. If anyone has already dealt with this model I would ask for some help

What are the symptoms after turning on? Is Stby completely dead? U1 sooty or just in the picture it looks like this? 0ohm resistors check, are there any fuses on the board?

Evidently damaged U1 - active converter. Replace, we'll see what to do next.

After connecting the power supply, no reaction - completely dead. The problem is that I can't identify what U1 is.

The only thing I could read from U1 is the first letter "W" unfortunately nothing more

Replaced U1 and all electrolytes, the standby LED is on the board is 12v - unfortunately no 5v.

I have a similar topic, it was also connected to 24V. A blown "P" fuse with replacement still does not turn on, but UD1 heats up terribly.
I read the WC5TN from it. 95% because it's difficult to see. However, I can not find anything about this arrangement.

Hello
I have the same problem, the TV was connected to 24V and it smashed the U1 system, did anyone decipher what the system is ?? Nowhere can you find a service center for this model ....

Buddy Krystian, what layout did you put in place U1 ???
Added after 8 [minutes]:
I suspect you have inserted the wrong U1 circuit because it is responsible for 5V ?? Somewhere I found on a parallel forum that you can insert a 7805 stabilizer and the TV also starts working ...

The U1 system is a 5V converter with the symbol WC6MD (it is nowhere to be found). I inserted, after removing the U1, the most ordinary 5V stabilizer with a current of at least 3A (e.g. 78T05). The TV works, there is 5V in the place described on the plate, only the stabilizer heats up a little.
