The Timing Control, or T-Con Board is a part of your TV’s LCD Panel Assembly. The T-Con Board is centered on the top or bottom edge of the back of the Panel and hidden under a metal or plastic cover. It is connected to the Main Board via the LVDS Cable, and to the LCD Panel via flat ribbon cables. Samsung T-Con boards are part-number specific, and do not require matching TV model number, serial number, or panel number in order to confirm compatibility.

If the label found on the back of the panel begins with LT, then the TCON board will be manufactured by Samsung and is identified by using the following part number pattern: LJ94- followed by 5 numbers and 1 letter for a suffix(LJ94-#####[A-Z]). The LJ94- portion of the part number will never appear anywhere on the T-Con board, but the rest of the part number can be found within a mix of numbers and letters printed on the board label. These labels vary in location, size, and color, and can also have a barcode printed on them.

Look for the line of text that begins with 1 letter, followed by 5 numbers, 1 letter, and then a mix of numbers and letters. Ignore the first letter and write down the five numbers and letter that follows. Should the T-Con label only have 4 numbers printed after the first letter, you must add a zero in front of the four numbers to complete your Samsung part number. Write LJ94- in front of these six characters, and you have successfully identified the part number for your Samsung T-Con Board!

– Search Scenario #1: Your Search Returns An Exact Match
Search your LJ94 part number on to find a compatible replacement. Typically, your part number will match the ShopJimmy Item Number.

– Search Scenario #2: Your Search Returns A Differing Item Number
If searching your part number directs you to items that have slightly different part numbers, take a look at the product details to confirm that your part number is in the substitute parts field. As long as your part number is found in the substitute parts field, this item will be a compatible substitute and will work in your TV.

– Search Scenario #3: Your Search Has Multiple Results
If searching your part number directs you to items that have slightly different LJ94 numbers, take a look at the product details to confirm that your part number is in the Substitute Parts field. As long as your part number is found in the Substitute Parts field, this item will be a compatible substitute and will work in your TV.

– Search Scenario #4: Your Item Is Out of Stock
If your part number is out of stock, be sure to check the Substitute Parts field on the product page for compatible replacements. These substitutes are guaranteed to replace your original board, even if the part numbers on the board do not match.

– Note:
Shopjimmy has found that after installing some T-Con Boards, mainly in Samsung and Sony models, the TV may require an update. This may require pressing the TV or remote control buttons in a specific order, or uploading new firmware via a USB flashdrive. Make sure to check the notes on any relative ShopJimmy product pages to see if an update is required for your specific T-Con Board.

    Hi perhaps you could shed some light? My SYNCMASTER T240HD monitor/TV was made in TIANJIN CHINA manufactured March 2009. Model Code on back cover is LS24TDNSUV/ZA Has been acting up after it appears to overheat. Either the monitor just freezes the image or it starts to blinking between a set of large horizontal red/white/blue bars and solid white or solid blue screens. It won't switch sources at that point, but turning it off for awhile and back on, it returns to normal. I've proven its the monitor by switching to another one and it doesn't happen so its not my video cards. So something is overheating. From some of your other videos and others I figured it was the TCON card. After opening …the tag on the inside has number LTM24OCT04 and it does NOT have a small tcon, it has one big long card that spans the entire length of the monitor and about 2 inches in width. It has several ribbons direct soldered and that go to the LED. Its part number is 24OCT04S2L V1.4. Have you seen one of these? I can't find any info on this, is this made this way so that it cannot be replaced easily?

    Hi, I have a Samsung LED Smart TV with a bad T-con board, an N mosfet or diode was bridged, so I replaced the entire T-con board with a new one, and it died within 3 minutes of install, T-con gets power via Mainboard, not directly VIA Power supply, should I replace Mainboard as well next time? I dont want to chance that the New T-con was defective, and have another one die.

    I am about to try the tea con repair or fix on my LCD LN S4095D Samsung, but it seems my symptoms are much different than others I've read about. My display seems to work fine with numerous cable TV boxes, yet when I try to hook up anything else through any other input I get vertical lines. Still TCon? Why cable boxes work?

    My LA32C350D1 is having double image problem and at time the blue color appears as purple. From what I seen on videos like yours I guess it's T-con board issue. My problem is locating it. I've searched all over for a video disassembling this particular model with no luck. I've managed to strip it down to the panel level, but I do not know how to go from there to the T con. If I get there I can get the part number as you have described here and buy it from you. Could you advise me please.


    This is the model number of my samsung tv. I am experiencing red lines all over the screen. From watching your videos i understand that this is a T-Control Board issue. I have uninstalled my T-Control Board, but am unable to identify the model number, so I can order a new one. Can someone please help me?


    Hi Jimmy, I have Samsung LE40D503F7W, don't know what's wrong, while watching TV appeared green lines, then Samsung LOGO, then TV turned off and only red light is lighting on the right corner. What should I do, please give me recommendations.

    I have a 52 inch Samsung LCD TV model number LN52A750R1FXZA.  It has a dark area in the center that runs from the top to the bottom.  Like a band in the center area that is completely  dark unwatchable.  It also has a double image on the right side of the screen.  It is about 6 Inches lower on the second shadow image.  There were originally 5 horizontal lines that were on the right side of the screen that showed for a while until the TV warmed up.  Is this a repair that a new T-con board would fix?  Any ideal on what would repair it?

    Hi Jimmy, I'm having a problem with my Samsung UN50EH5000F.The standby light is paler than normal, and it does not turn on when I activate the power button.When I disconnect the main panel from the power panel, the backlight comes on; However, as soon as I use the 14 pin cable to reconnect the main panel and the power panel, the backlight goes off.I replaced the main panel, but the problem is still going on.Could there be a 14 pin cable issue?  Thanks! Sincerely, Lena

    Hi Jimmy,
    My Samsung flat screen TV Model Code LN32A330J1DXZA has a white screen when turned on.  The picture is mostly faded and mostly white, though you can make out some of it. Sound is fine. Can you tell me what part may need replacement and if I can order it through you?  Thank you!

  15. Bill Kurz

    Hi Jimmy:  I have a samsung LED TV that the picture went out on.  I do get sound and with the lights off I see there is back light.  When I turn it on I get a second or two of horizontal lines and then just back light.  The power light blinks 3 times.   Model number UN46D6420UFXZA.  I have not taken back off of TV yet.  Do you think this is the T-Con board?

    Thanks Bill

    My TV model number is Samsung LN40B750U1F. When I switch on the TV audio and video comes fine for few seconds, then display goes black and audio continues. When I move myself close to the TV I can see the characters moving in very dim black scale. When I turn the TV OFF and back ON same cycle repeats. What could be the problem?

    I followed your troubleshooting guides and believe I have a bad T-con board on my Samsung TV model UN60EH6050FXZA bought 2 years ago. Hopefully I can find the T-con board available here and have the problem fixed. Thanks,

  20. DCHUA

    My 50 inch Samsung LED Model UN50EH5000 FX Series 5 suddenly went black no picture.  Perfect Sound.  Is this the T-Con Board? or something else.  The warranty went out 8 days ago.  If it is the T-Con is this something I can easily fix myself?  Not much of a DIY girl.  Thanks so much.
