Re: Samsung LE40A656A1F Black to Red Screen Error

I'll check that out in the morning Tom, I am actually starting to wonder if its just down to it been turned off for so long, its gone on and off now twice but for a good few hours has stayed normal, Ill play if from here for now and see what happens, cheers for the good advice thus far however

Re: Samsung LE40A656A1F Black to Red Screen Error

Yes its set to Default, inside that menu I did notice a EEPROM reset option, as you said corruption of that could be a possibility would a reset be advisable?

Try it, but since it is going away occasionally it sounds like a loose connector or a T-con problem.

OK mate I'll give it a shot but I think your probably correct with the latter explanation(s) Ill give the LVDS a pull and put it back in, if not I've already priced up both a LVDS & TCON replacement, Ill buy the LVDS first has its the cheapest, if that doesn't solve it then the TCON haha finally the mainboard, even if non of them work I've got the parts and can resell cheers for all your help Tom you've been a star

Re: Samsung LE40A656A1F Black to Red Screen Error

Well I'm pleased to say after opening it back up and unplugging the cable which runs from the main board to the t-con and cleaning around the t-con (some area I'd previously not cleaned) the problem has been solved with no extra costs incurred

Not sure if it was the dust all over the board of the t-con or the cable possibly been knocked when cleaning it first time round :? but won't lie I'm a happy chappy and its been almost problem free since.

So what is the problem you may now ask hahaha.......

Well I wired my spare desktop PC upto it but having wired up the soundcard to the selected ports on the back of the tv I'm not getting any sound, does anyone have any ideas to why this may NOT be happening lol, I really wanted to use it so I can skype my family round the world don't fancy having to buy external speaker system just for the PC sound, the PC soundcard works fine I've checked it so the fault definitely lays within the tv or its settings?

Where have you connected audio in? This TV has PC audio in port, as well as DVI/HDMI audio in, you can select which one the PC uses I think from the menus.

Re: Samsung LE40A656A1F Black to Red Screen Error

Mmmmm did not know that, well I attached the PC via the PC port and a normal PC monitor cable, I used a mini jack to RCA lead to wire the sound card to the two RCA ports marked PC Audio

Try the little jack like a headphones jack, I think that is PC audio input.

Re: Samsung LE40A656A1F Black to Red Screen Error

I just repaired a Samsung with a similar issue by cleaning the connectors at both ends of the LVDS cable. It may not help your issue, but it is worth a try.

THANK YOU!!!! I had one that was doing this and that's all it was!!!

Yep, info-menu-mute-power works on every Samsung from ancient CRT RPTV to 6 month old plasmas.

Just fyi, this does not work on US Samsung TVs. I know you and the original question poster is in the UK, but I just wanted to toss this out there so if someone else from the States come across it, they don't think there is something more wrong with their TV when it doesn't work for them, but thank you for posting about it!
