Facing TV Problems? Ask a TV Technician.
Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out, Matt.
Could you give me the full model number of the tv, please?Does this happen on all inputs/sources?Does it also affect the samsung menu screens?Does it improve eventually, or only after powering off and cooling down?
Thank you for that information, can you please send me the above requested info as well? You can also upload a photo with the paperclip/attach icon.
Thank you for confirming,
that can be a hardware issue (thermal fault, bad solder joints, etc), or it can simply be from contamination that is causing over heating.Vacuum off all the external vent holes, and blow it out as best you can with compressed air. If you are up for it, removing the back cover would facilitate this more easily (carefully, power unplugged, no hdmi connected).
If no change, we'll address hardware issues next.
Yes I'm here, your replies have just come through.
I'm seeing a pink stripe on the left side of the tv, is that always there, or was it just that particular show/image?
Both issues are pointing to a faulty tcon board as the primary suspect here, though it could be the main as well.
Is this something you are looking to repair yourself?
Yes it is a thermal fault, but the underlying circuit board would need to be replaced.
If comfortable doing that yourself and the part can be found it may be worth it.
If not, based on the age of the tv, it isn't worth fixing - you could buy a new one for less than the cost of repairs.
Yes searching for it now
I'm having trouble finding anything, probably because you're in AU.
Can you take the back panel off, and look at the board at the top in the middle, that is the one we're looking for. It should have a board number marked on it.
We can't do email, but you can attach here same as you did before.
The main board is the one with the input ports
power board is the one with teh power cord
and the remaining one is the tcon
Yes it is the one in the middle, but I need a closeup of that board please to see the markings on it so I can get a part number, then hopefully find a part source.
Thats it, thanks.
Here is one: http://www.ebay.com/itm/Original-T-Con-Board-Samsung-S240LABMB3V0-7-BN41-01663-BN41-01663A-For-46-TV-/262152303911
No it should not matter, we are matching actual part numbers, I saw S240LABMB3V0 on your bard, correct?
Only that it is an intermittent fault, and with having the back off it can probably breath a bit better and keep cool.
The old board comes out with a few screws and wiring harnesses, it doesn't need any soldering, it is a plug and play part.
When you got the board, was it from ebay and did you confirm with the seller that it was for the 55"?
Well if the part number matched exactly, it should be fine, but the listing does specify that the seller had ones pulled from both sizes; to rule out the possibility of a difference (even though the part numbers look to be the same) I'd contact the seller to see if you can exchange it for the other, which will also help as a verification step just in case this board is faulty by chance. If still no change after that, then this is looking more like a panel fault.
I said it would not matter if the part number was an exact match. I don't have your board in front of me to verify those, and the listing gives options to choose either.
If there is a different prefix/suffix accounting for the size, then that is what is to be used.
I cannot contact the seller.
Since he has multiple items listed, I would not expect any difficulty in exchanging it, which is a worthwhile step even if it were the exact match up front, simply to isolate the possibility of the new board having a fault of its own.
No, I'm not brushing my hands of it, I'm telling you that in the listing he gives an option for another size as well.
I'm not sure what you mean, but please remember this is a diagnostic process as well, and the tcon is not even the only possibility, just the most likely failure point. If one board doesn't work, we move on to testing another.
