Location of t-con board

Can you tell me where the t-con board is located in my tv? Is it easily accessible? When I replace my board is it an easy fix? Pop the old one out and the new one in? Is there any things I should be careful of?

    Dear Bill,

    Believe it or not, some people, even women!!!, have knowledge of fixing and understanding anything. So, to say it is difficult is kind of bias. Fortunately I have been able to go through life not paying the overpriced repair men to fix anything from my plumbing to my electronics! I am handy and resourceful in that way. As, are many other (women) or men. Usually I try to get some instruction before I tackle a project. Thanks for the caution and I will face the consequences if I screw up. Hey, I think I could land a 747 with a little instruction. (Not to sound pompus). I am not trying to be rude but, the average joe can probably do a lot of the things that you can do, even though they don't have a background in electronics or tv repair. The way the economy is these days we have to cut costs any way we can. As for me, I am not lazy, I will cut the corners, do the research to get the job done at a reasonable price. I won't waste a thousand bucks to have somebody (qualified) to do what I can do myself. After all, isn't that what this web site is all about? Fixing it yourself? Through knowledge and courage is power.

    Thanks, Christine

I didn't mean to sound like a know-it-all Christine I've seen many on this board that have tackled jobs just as difficult and I had no idea you were a woman - gender has no bearing... There are women in this field just as qualified as I am and some that are more so. But I have been lashed at for not giving enough fair warning that the job is a serious one. Twenty three years as a tech I wouldn't be here if I wasn't trying to help some people from paying large repair bills...
That said, I wish you all the luck! Hope you get it repaired and find my experience useful and will drop me a kind note when you get it done....

The t-con is a small control board at the top of the panel above the smps under the shield and only has four screws holding it to the frame. Is it an easy fix??? It is no more complicated than landing a 747 with some minimum verbal instruction from the tower as you decend... Most of the boards in these lcds and plasma units are HIGHLY static sensitive and while it's not a difficult repair, changing that particular board, it's getting to it that will be some cause for concern.
What I'm trying to say and not be rude is that you might just be better off letting a qualified shop do this one and warranty the work. You can cut some of the expenses by taking the unit to them and if you want to research a bit try the NESDA site locator to find a reputable shop in your area. Electronic repair like any other skilled endeavor REQUIRES some basic knowledge and tools. I don't really have a measuring stick for how much but I can example this way - - I've been a technician for more than 23 years. I went to school six years for the basic theory and application including my ojt time. These many years later and I'm still spending approximately $6,000.00 a year to keep up-to-date on how to repair all the latest in technology. For me, on a scale from 1 to 10 with 10 being the most difficult and 1 being a breeze this job would be a 4 because there are so many layers of boards and shields to remove and then possibly resetting some of the parameters in the service menu when done. That said, I could make a mistake and cost myself another part or board.
Hope this helps!

I have a Sony KDL-43W755C LED TV with a T-CON board problem. Opening the back I can see the BMX board but not the T-CON. Can anybody indicate its location? It doesn't seem to be top dead-centre.

The T-con on this model should be located in the bottom center of the TV. When the back is off you should see it bottom middle under a metal shield.

Only half of the screen is working

Most likely it is the screen that is bad and it probably can't be fixed however it is worth opening up the TV and getting to the T-CON board, wwhich drives the LCD display.

The T-Con is located at the top middle of the TV looking from the back and it's usually covered by a shield cover.

You can tell it easily by its location and the large cable that goes to it from the main board.

The board's ID should be 4046HSC4LV3.3 (make sure to verify that once you get to it!) and it should look like this:


What you are looking for is the white cable that goes out from one of the two connectors at the top of the cable and goes into the LCD display.

I'd recommend pulling out the one that's on the side of the half that does not work and inspecting it for burns.

You may also swap it with the other.

The odds of succeeding are low, even if it is burned and you replace it, but a few times I was able to fix a display like that.

Replaced panel, mother board, analog board and digital board and still the tv turns on then immediately off. HELP

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$???????

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $100

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well, so if you would like to view them check it again soon. Let me know if I can do anything to help.

Hope this helps and Good luck.

T-con board for your samsung

The t-con board is very easy to replace. The only problem is you need to take a bunch of stuff off before you can get to it. How to replace it:
1. Take off the back of the TV
2. Unplug all the wires connected to the middle boards, you will need to take off the whole assembly that the 2 boards are attached to, the main power board and audio/video board.
3. The t-con board is under the shiny metal cover near the top of the TV. There are four small screws holding the cover in place. (You should be able to see the cover when you take off the back plastic cover of the TV).
4. There are 3 connectors attached to the board. The white one that comes from the audio/video board and 2 small ribbon type that connect to the front of the TV, probably the LCD panel.
5. The 1 separate connector is self explanatory. The other 2 are a little more difficult. They just slide into place. When you look at the connection, there is a brown "flap" holding the ribbon in place. You need to flip it up from the top side of the TV.
6. The old t-con board just comes out and the new one goes in.
Hope this helps!
Let me know if you have any other questions.
