Re: Samsung LN46A550 Picture Issue

So I just wanted to update this and close it out. I installed the new tcon board and it fixed the problem completely, the picture is fine again. I just wanted to sincerely thank all of you who helped me troubleshoot this. The measurement of tcon voltages was a key item leading to a good Dx and fix. I am active on a large Home Automation forum where there is a similar level of help we all give and it's great to see that here as well where everyone chips in and helps the newbies and stuff, so thanks again for the assist.

I have a Samsung LN37A550 with same picture issues as the photos shown by T-Rex at beginning of this thread. Based on this thread and other things I've read on this site, it seems to be a T-Con board problem. I just removed the T-Con board and ordered the 'repair service' from Shop Jimmy [they are out of stock on new boards].

I will return to this thread and post the results in a week or so when I get the repaired board back and install it. Thanks for all who posted here - this really helped diagnose the problem.

4/20/14 Update: I got my repaired T-con board back from ShopJimmy yesterday and just installed it back in my tv [LN37A550] today - the picture is back to normal and everything works find.

Thanks so much to T-Rex and everyone for posting the info in this thread; before I came upon this info i was thinking would have to junk this tv and buy a new one. But thanks to this forum I am back in tv viewing business!

Talking of replacing boards - I always repair and replace AS15 / AS19 chips because my theory is at least you know its 100% working with no compatibility issues.

for those that cant replace the chips there are services on ebay for TCON repair here in the UK so imagine other countries have people offering similar services.
