Help to replace integrated circuit.

Very good afternoon, as the title says I require your wisdom of how I can replace an integrated circuit, in my country I do not get it, and I know that another integrated circuit can be put to replace this one without needing to have the same serial number, making it With a couple of resistors and knowing which are the pins of the integrated circuit that I want to replace, the question is that I can't find the diagram of this integrated circuit and I don't know why another integrated circuit could replace it. This circuit belongs to a kalley tv board model K-LEDHD32HDSZT2 and the board model is: RSAG7.820.6625 / ROH. attached image of the integrated circuit which I need to replace, I really appreciate your help and your answers.

Thanks for your answer, the question is that I can't find the datasheet of that controller, it doesn't appear that way, so I made the query thanks.

Thanks for the link, the question is, I don't know if I read it wrong but this is 7 pins and the one with the board I'm working with is 8 pins. I apologize if I could not read it.

Perfect friend thank you very much, I found it on a Chinese page but I found it, now the question is: why else can I replace it to adapt it to the board? since for them I must use 2 resistors one of 100 ohm and another of 1 k. Thank you.

is that I already have the datasheet, according to the video I saw, it says that the one used for this type of replacements is the viper 22A, but I don't know what you say, if I can use that one or should I use another one.

I leave the OZ531T controller datasheet link http://www.go-gddq.com/html/s225/2017-07/1525561.htm

ok I understand, but the FB pin can't go straight right ?, should it go with the 100 and 1 k resistors?

Friend Victor, I have a question for you or anyone who knows, any data would help me a lot, I can replace the OZ531T with a MAP8800 or MAP8802 ?, I have been comparing and I see that both are very similar thanks.

I understand, but the question is how it would work because the TV is a single board, in the same board comes the source and the main. How would I do it? Because if the TV were like that of an LG that has a separate main board and main board. This brings both functions in a single plate. Greetings and thanks for your response.
