sharp TV:T-con?

a

It is a small controller board the controls the LCD. It often has a good few ribbon cables that connect to the top. Some manufacturers make it into a bigger board by adding functions that could be elsewhere. Apparently it stands for timing controller and splits the signal up for the LCD ic which is on/in the screen.

I think of it as a type of multiplexer, but I could very well be wrong and can not substantiate this.

Pulled this from a site but can't link yet jestineyongdotcom/diagnosing-t-con-board-with-gamma-distortion.

From reading, I get the impression that there are quite a few issues caused by bad connections. Then check tho power, and if that is not working it is the T-con board. Number one duff component is the electrolytic  (or large value) capacitors, but with some ESR meters you can measure the ESR in circuit (approx £40 off ebay) and the TV must not be on, and the caps discharged to measure them.

About 10 years ago i threw away 5 working TVs with tubes, and was shocked the see the the vast majority of TVs at the recycling centre were flat screen ones, and a few were really big and must have cost thousands then.

But if you are asking question like 'what's a T-CON' it might be better for you to take it to a repair shop who knows what they are talking about. It seems some answering on here don't know either - the multiple ribbons joining to the LCD panel are nothing to do with the T-CON but part of the actual LCD panel itself. Those are most definitely not something a home tinkerer can do anything with.

Some for sale on eBay.....You might get an idea from that....See HERE..

Once you could get a bag of replacement parts that commonly go faulty on a board. The idea was you search for the board number, buy the bag of parts, unsolder the existing parts and put new ones in their place.

These fixes often cover the common electronic failures for that board, and does not necessarily fix your problem, but it often did. Personally never used them, but have seen things like this being used on our work kvm, by our third party engineer. I was the one to solder the components in as the third party engineer had never used a soldering iron before.  If you do not know what you are doing, for safety sake dont touch it.

Update: I gave up trying to identify/replace the t-Con and just pushed every connector I could see in firmly and then screwed the back on again. Amazing! TV works perfectly now. Well, it's been 36 hours now so fingers crossed.........

This really goes against 'repair it yourself'. I have personally repaired a couple of monitors and TVs, and have got to this point without encountering the term T-Con. Can you answer the question correctly, and help by sharing knowledge? What is a T-Con? 'a' had a crack at it at least, and admitted to not being an expert.

Some descriptions of what it does at https://www.quora.com/What-does-the-T-Con-Board-in-a-TV-do
Basically a small interface board which interfaces between the TV main board and the LCD display panel.
