Are you talking about this one

Because this monitor doesn't have speakers, an audio board or even audio entries so there is no audio chip to fix.
On the other hand if by audio chip you are referring to the chip that amplifies the sound then it's very easy to replace: you unscrew the safety screws that are keeping it glued to the radiator, unsolder the pins and it will just pop out. Finding one will be relatively easy, there are dozens of sites that are selling  IC like that, just google for it. It will cost you less than $50.

Sounds like T'Con board fault. Contact any service technician. When video signal interfaces, it goes overloaded. If you wish to get some details; check the site linked here. Pull up older posts.

Samsung 403T no power


1) Fuse is good?
2) You must have 5vdc stanby voltage the minute you plug the set into the wall, this is a must have before going further. Please look for that first, then report back what you find. Pictures and Sch will be a great help. See example of my pictures here: http://s807.photobucket.com/home/budm/allalbums

Samsung 403T 40'' monitor has no power. (CK40PSNB)


FYI, I have found the real solution for this issue with Samsung 403T. It is a design flaw which leads to this problem after a while. Luckily, it can be easily corrected, but it requires medium soldering/electronics skills.

Anybody interested in how to fix it feel free to email me and I'll provide you with the solution. Please make sure that the symptoms of your monitor are exactly the same with the ones described above.

I only get power saving mode on my screen then screen goes black


inside the power pack is a pulse IC chip they fail and cause all kinds of havoc also caps can cause issues unaccounted for, I would start at replacement of the IC about 2 dollars on E bay, and replace any bad capacitors you can see, they look domed or are leaking color from the top creases. after that get back with me and we can either proceed or you can rate me fixya, have a great weekend
