If your television is a Smart TV and it does not play anything, it remains in the logo, it can be mainly due to 2 causes, the first due to electrical damage and the second due to de-soldering of internal components due to overheating.
The failure of staying in the logo and not reproducing anything is very common today, all Smart TV brands present it at a certain time of use. Electronic equipment is designed to fail to exceed its maximum usage time.
For your Smart TV to continue using it and not buy a new one, there are several techniques to solve the problems that appear at a certain time. Sometimes they are simpler and easier to solve problems, such as lowering or raising the brightness of the Smart TV.
Try to take your team to the best service where they give you a guarantee for what has been done to your Smart, a trustworthy and reputable staff to be able to obtain the best result or solution whatever the case.
Does your Thomson Smart TV stay on the logo?
This type of breakdown when your Smart TV does not start or the black screen is placed , the first step would be to check the power supply, if it does not start or have sound. We must also verify the microprocessor of the Smart TV, on the electronic board, it incorporates the memory and other things.
Then you must reballing it, that is, remove the chip, clean the welds with a special liquid such as flux and the balls and finally put it back in place with a new weld, this new weld will give it a better finish and durability.
Another way would be to impregnate with flux or some liquid similar to the micro controller, this process makes the tin go where the tin is. To make a homemade reballing, we can use a hot air soldering iron and carefully pass it to the micro controller, not to exceed 70 ° c.
At the end of the procedure with great care, you should wait for it to cool down, that is, take it to room temperature before turning it on. Similarly, if it does not work, the last option would be to send the plate to an external workshop specialized in reballing or buy the entire plate.
Your Sony Smart TV does not start?
When it happens that your Sony Smart TV stays in the logo and does not reproduce anything, because at first glance it is a problem of updating software , and you immediately proceed to reinstall the software, in this way you solve the problem.
Another solution option would be to check the bias voltages for the microprocessor. It is important to know that the bias voltages are between 1.2, 1.8, 2.5, 3.3 and 5 volts, which if not in those values would be the cause of the problem.
Let’s make sure that the power supply is correctly sending the supply voltage to the card, two important voltages that must arrive are 12 and 5 volts. The 12-volt is used to feed the sound.
With the tool to be used, that is, the voltmeter, you can verify all the polarization voltages and in this way know if they are in the correct range or not and locate the fault.
What is a Smart TV reballing?
For all those equipment that stopped working due to overheating, the video chip resoldering is applied, better known as reballing, reballing, that is, soldering the small solder balls, is a cheaper procedure than replacing the motherboard.
With the help of a specialized tool, the necessary temperature is applied to desolder the components without damaging them, all the solder is cleaned to proceed to solder with a more resistant solder and finally join it to the motherboard.
Then you should check all the other components such as the video and audio cards. With reballing, your problems with your latest generation electrical devices will end.
Rebelling is something new that came to stay and solve all your problems with electrical appliances that have a microprocessor, it is very easy to do it either in the home way with a heat gun or by taking it to a reballing machine service.
