Hi again folks!
Over the weekend an associate and I worked on a Neotec 2515C monitor chassis that is simply NOT working properly. We have a vertical roll issue and some strange horizontal tearing.
This chassis was swapped into other games and displayed the same behavior, so we know that it is faulty. Solder joints were checked and reflowed, caps were all replaced but the issue still persists.
He told me that the last thing we should try is replacing the horizontal and vertical ICs. So I removed them from the board; one has the following markings, "LA7851 5A6" and looks just like a regular chip, the other is "LA7836 3G3" which is very small and sort of looks like a hair pick.
My questions are: Where can I find these? I've searched and found LA7836 and LA7851 but each has different 3 character codes underneath it...what IS that code? I want to be sure that we get the correct chips.
Thanks in advance for your help!
