I love your sense of humor.
 
I continued on my thread trying to repair my PCB.
ok well its 6:36 am i have been working all night shoot that 16 over so i can ship your package out .   i am leaving here and heading to the post office… then i gotta get home and get a couple hours of sleep before i start my other job.

Well. we return to the issue.
 
The question raised was whether the Video muxes (F253D) can be the cause of the image appears a little cut by top.
 
Are the responses are valuable only if they are reasoned.
 
Thank you.
Well, you want to try the muxes, knock yourself out, no one here is going to say no.

Without the board in hand I cant give you any advice on which part to replace, or to be specific on what. 

The problem here is, the board needs to be "TROUBLESHOT" Meaning, you need to know and understand electronics to really fix the issue without becoming the next "parts swapper" 

So in other words the board needs to have some troubleshooting done to it with appropriate equipment to figure out exactly which part is bad. So unless you are familiar with electronics repair, and know how to troubleshoot, you are going to chase your tail for days. 

So either replace every part on that board and hope it works, or send it to someone who knows how to fix electronics. 

nuff said.

Yesterday I unsolder and swap all the F253D IC's :
