Re: Samsung 710n bad image

I turned it on and it suddenly worked! No problem at all! Maybe some bad cable connection.... Thanks for your help

Re: Samsung 710n bad image

IC106: 5AG4? 5A64?
IC201: A81SC-Q530
IC600: PF4AG FDS 9933A
IC601: APL5522-AH70E

No IC501, or at least I couldn't find it. I'll check the manuals.

Re: Samsung 710n bad image

After about forever, I'm back with the photos of the board
I didn't take those of the power board because I've swapped it with one that I know for sure it works, and the symptoms persist.
Thank you for your directions!...

Re: Samsung 710n bad image

The pictures were taken using a new working cable, so it shouldn't be the cause. I've got a soldering iron and a multimeter, I should be able to go through the steps required to replace a bad cap or identifying a failing component. I'll be able to disassemble the unit in a couple weeks, maybe I should have waited before posting but I thought that maybe someone could give me directions based only on the symptoms.

Re: Samsung 710n bad image

Thanks for the replies!
@retiredcaps: I already uploaded these images for using on another forum, and deleted them from my computer. If it's that important I can download them and reupload here. As for the boards photos, it will pass some time since I don't actually have access to it right now.
@jayoung: yes it's quite similar! Thank you... the difference is that the osd is equally distorted (as you can see in the first image)

Hi all! first post
I have bought a used Samsung Syncmaster 710n, it worked fine for about a day then the image went bad, as you can see in those pictures:

I was not present when it happened, but I know that it was connected with a bad cable (such as moving it changed from a perfect image to a purple tint), and the power cord was wrongly attached such as ground was not connected. I don't know if that information...
