How to replace T-con board?
In some case, the other boards may have to be loosened or removed to allow access to the mounting screws and clearance to remove the T’Con board. The issue of most concern is keeping track of the heat transfer pads, stand offs and insulators. The T’Con is heavily shielded and it si ease to have one or more of these components accidentally fall out of the assembly when removing. T’Con assemblies that use multiple heat transfer pads must be removed slowly and every attempt must be made to keep the shield and circuit board together as they are removed from the unit. Check for any service bulletins pertaining to the model and panel design that contain the subject lie of ‘T’Con heat transfer pad locations’ for pictures to show the proper location of these components. This site itself has covered disassembly procedure to some model LCD TVs, here. Pull up older posts here, or see the site in Timeslide option, which can be accessed by the drop down at the top left side of the display window. It will make search the easily.
What are the problems with a T-con?
It is virtually impossible for the video process circuit to cause a problem on a specific area of the screen. Failures on this board usually appear as distortions, color level shifts, video level shifts or noise that involves the entire picture. The T’Con can generate symptoms that appear to be video process related, but the video process circuit cannot produce the symptoms of a failed T’Con board circuit. T'CON FAILURES
What is the T-con function?
What is the T-CON Function? The T-CON (TFT Controller) is responsible for; 1. Driving the TFT panel. This is usually accomplished by two LVDS type cables between the T-CON and the th Panel. P l The Th panel l cell ll structure t t i is broken b k into i t Vertical V ti l columns l and d H Horizontal i t l rows. • Horizontal Resolution: On a panel with a resolution of 1920 X 1080 we must have 1920 X 3 columns, because a pixel is comprised on a Red, Green and Blue cell. So there will be 5760 individual cells in rows across the screen. To turn these cells on and off, the panel will use vertical address lines or electrodes driven by y a small board located inside the panel. p In this way y we can turn the colors on and off accordingly to recreate the correct colors required to recreate the image. • Vertical Resolution: On a panel with a resolution of 1920 X 1080 there will be 1080 horizontal rows of cells running across the panel. These rows are being driven by a small board inside the panel. By 2.addressing a particular cell via the vertical columns and turning on a row of cells, only the cells being address by the vertical electrodes will be activated. activated The number of horizontal rows determine the panels Vertical resolution. TFT: Each cell has is driven by a thin film transistor called (TFT) and a capacitor. When that cells is addressed (turned on) the capacitor will charge and will remain charged until the next refresh cycle. Generally speaking, when the cell has no power applied, it blocks the light from passing through, when it turns on, dependant upon how long it is on, allows more or less light to pass. In this way we can control the brightness level being output by that cell. Panel Voltages: The T-CON is responsible for developing panel voltages. These voltage will vary dependant upon the type of panel utilized. utilized We generally state there will be 4 voltages that are always being delivered to the panel, -5V, 3.3V, 16V and 26V. However, there may be more according to the type of panel being used. Backlights: Since the Liquid crystal panel does not generate any light of its own, there must be a light source behind the panel. This light source is called the “Backlights” called BL here after. The BL can be either florescent (EEFL or CCFL) or they can be LED. The T-CON is not responsible for turning on the BL.
Do you need to reverse engineer a schematic?
Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
Can a T-con board cause a LCD panel to fail?
Some LCD panel failures could possibly mistaken for T’Con board issues. Other than damage to the LCD glass, most panel failures are isolated to a particular area of the screen. Since the T’Con disperses the pixel data to groups of line and column dirve IC’s situated on the outer edges of the panel, it is unlikely that more than one of these IC’s would fail at the same time. Multiple columns of struck on or stuck off pixels are therefore, more likely to be the fault of the T’Con circuits. The same applies to a single row of lit or unlit pixels. The T’Con simply cannot cut out a single line of information.
