Samsung LN46A530 - Bad T-Con Board?

[bheemsoth]

Good morning,

New member here looking for some help with my 4 year old Sammy LN46a530. I have some experience with TV repair (optical block replacement on KDS-R60XBR2), but LCD's are a new beast to me.

Anyways, over the last couple of days we have started seeing these red vertical lines on the screens as well as red "wavy artifacts" (best way I can think to describe it). These image issues appear on the OSD as well. The distortion and lines usually appear after the TV has been on for about 15 minutes, and sometimes go away after 30-60 minutes.

After some research I am thinking this may be a T-Con issue, but as I said I am no expert. If anyone has any input, it would be much appreciated. I have attached a few pictures to assist in troubleshooting.

Thank you in advance!
Brian

Probably a T-Con issue, but first I would try cleaning all connections of LVDS cable(s)/connectors, as there have been some LVDS issues on similar models. If you can move/press on/otherwise manipulate the connectors at both ends, you may see the problem go in and out, if LVDS cable is your issue.

Thanks for the quick reply! What would be the best method of cleaning the LVDS connectors?

I had one of these not to long ago, but it was much worse then yours and it was making a horrible sound too. I had to replace the mainboard.

Eeek...not what I was hoping for! Were the vertical lines and artifacts similar?

I just went back and read your thread - seems like a slightly different set of issues.

I'm going to try to clean the connectors and cables tonight. Hopefully it will work out!

Just wanted to come back and update this - my issue was indeed a loose LVDS cable. The TV has been stable for 2+ weeks now.

Thank you very much for your help! You have to love free/cheap fixes!
