If your TV is Smart TV and does not play anything, it stays in the logo, it can be mainly for 2 causes, the first being electrical damage and second due to gluing of internal components due to overheating.
Breakdown stay in the logo and do not reproduce anything It is very common today, all Smart TV brands present it at a certain time of use. The electronic equipment is designed not to exceed the maximum service life.
In order for your Smart TV to continue to use it and not buy a new one, there are several techniques to solve problems that arise at some point. Sometimes problems are simpler and easier to solve, such as lowering or increasing the brightness of the Smart TV.
Try to get your team to the best service, where they offer you a guarantee for what has been done to your Smart, a reliable and trustworthy staff to get the best result or solution, whatever the case.
Does the Thomson Smart TV stay on the logo?
This type of malfunction when your Smart TV does not turn on or the black screen is placed, the first step would be to check the power supply if it does not turn on or has no sound. We also need to check the Smart TV microprocessor on the electronic board, incorporates memory and other things.
Then you have to play again, ie remove the chip, clean the soldering with a special liquid such as flux and balls and replace it with a new solder, this new solder will provide a better finish and durability.
Another way would be impregnate with flux or something similar to the microcontroller, this process makes tin go where it is tin. To make a homemade reballing, we can use a hot air soldering iron and we can carefully pass it to the microcontroller, not to exceed 70 ° C.
At the end of the procedure very carefully, you have to wait for it to cool down, ie take it at room temperature before turning it on. Similarly, if the last option does not work, send the card to a external workshop specialized in reballing or buy the whole plate.
Your Sony Smart TV does not turn on?
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 to update the software and proceed to reinstall the software immediately, this way you solve the problem.
Another solution option would be to check the bias voltages for the microprocessor. It’s important to know that the bias voltages range from 1,2, 1,8, 2,5, 3,3 and 5 volts, which if not within these values would be the cause of the problem.
Let’s make sure that the power supply sends the supply voltage to the card correctly, two important voltages to be reached are 12 and 5 volts. 12-volt is used to power the sound.
With the instrument to be used, ie the voltmeter, you can check all the bias voltages and in this way you know whether or not they are in the correct range and you can locate the fault.
What is a Smart TV reballing?
For all those teams that it stopped working due to overheating, applies the gluing of the video chip, better known as reballing, rebolaring, ie gluing small balls to be glued, is a cheaper procedure than replacing the motherboard.
With the help of a specialized tool the temperature required to desolder the components is applied without damaging them, all the solders are cleaned to continue the soldering with a stronger solder and, finally, to join them to the motherboard.
Then you should check all other components, such as video and audio cards. With reballing your problems will end your electrical devices the latest generation.
Rebellion is something new that has come to stay and solve all your problems with electrical appliances that have a microprocessor, it is very easy to do it either at home, with a heat gun, or to take it to a reballing machine service
