    Hi mark Even though you distinguish the number of IC, whatever it may be; you can\'t replace it by any way. It is a surface mound device, in short and SMD IC. You only can replace the T\'Con board as card basis. So, take a look for it. You can see the details of the number that printed on the board, and only with that part number, you can even search for its availability.

This answer is generic:

Most of the time they use fuse resistors. Sometime there a number of them. They are not all the same. This is not a simple fuse. It is a resistor combined with a fuse. You would need the service manual to properly identify the fuse resistor and have its spec. You would then have to order the correct one from a parts distributor. If it cannot be replaced generically, the original would have to be ordered from the manufacture.

In any case, if there is a blown fuse on a power supply board you can be sure that there are failed components that are most likely shorted. This would mean that the board would have to be troubleshooted to find and replace the defective parts.

Most of the circuit areas and the boards in these sets are not supported to be serviced at the component level. They change the defective boards as in the same process as servicing computers.

As for the heat problem, if you can find someone who is technically very competent, maybe he can custom install a fan for the area that is getting heated. It should be possible to find a 12 volt source from the main power supply to run a small fan to assist for extra cooling.

If you have your set in a cabinet, or if it is wall mounted it may run hotter. We found that sets that are wall mounted tend to fail more often because the heat can reflect off of the wall back in to the set. Cabinets tend to not allow the heat to dissipate as well as out in the open.

Why is my TV burning through T-Con boards? Ever time I replace one, it works for 2 hours and then I lose picture again. I've replaced 2 so far.


Hope the TV have problem with the either power board or the lcd panel. Try to check the power supply is its produce correct voltages mentioned on its connectors if you need help then check the video for that. if the power supply finds ok then you have problem with the lcd panel. In lcd panel there is a some ics which used as the driver of the pixels. the tcon sends data to these ics. and if any onf the ics draws more current from t con board then it can dame the t con. They are not replaceable one ,its integrated to the panel. if its faulty then you have to go for a new panel for that tv. And it would be a expensive repair.

Why does the screen turn white after 10 minutes?


Probably the t con board have problem. the power regulator ic on the tcon board make this problem. As ist an smd ic you have to go for a new tcon board, because its not possible to replace the ic with normal soldering irons. you need smd rework station for that purpose. And also on more thing in some tvs the t con board is integrated to the lcd panel. if so its not possible to replace only the t con board , you have go for a fresh lcd panel. it would be a costly repair. because the panel is the costliest part of the tv. Any why check the video to understand which one is the t con board. if you find one in yours then try to replace it with new one. hope your problem will solved

VERTICAL LINE ON LCD TV


Hi,
You didnt specify the brand and model number of your TV any way the above mentioned problem can occur when the T-con board of the lcd Tv have some problem. There is no repare possible with these boards. The t-con board controls the pixels of the lcd panel. When any one of the out put from the t-con is faulty then the specific pixel or row of pixel will be absent. That's we see as lines or missing pixels. You can find the T con board normally in the bottom centre or top centre of the LCD tv covered with metal cover or aluminium foil. There will be a part number in the board. You have to replace a board with the same part number.

Some time there will be some loose contact in the connections of these board can cause these problems. Before going for a new board remove all the connection to the board and then reconnect it. If then also the problem is there then you need to replace the t con board. This is a common problem to the lcd TVs. Normally t con board will look like one in the picture. If you need any more assistance fell free to contact me through fixya. Next time when you post a question remember to add the make and model number of the product.

Screen turned white, only sound to hear


It tuns white because he T-CON board is not working due to blown fuse on the board or it is no getting the voltage from the main board, you can check for voltage at the T-CON fuse, you need to find out if the T-CON board is part of the LCD panel assembly or it is its own assembly, if it is part of the panel, thne it will not be worth fixing since the new screen will be needed.

There is a board on the LCD panel towards the top of it that is called the T-Con board and is sometimes included with a new panel. If it is not then they had to transfer the old T-con to the new panel. If this is the case then most likely the T-con board needs to be replaced. The servicer will have to verify and order by model and serial number as there are usually different part numbers for the T-con board. Please take a few moments to rate my answer. Thanks...
