Often people ask themselves the question of finding a true TV manufacturer or a circuit or firmware for a new brand. There are several techniques for determining the chassis of a TV.
It is necessary
- - computer with internet access;
- - browser program.
Instructions
Step 1
Please note that many brands, i.e. trademarks are not TV manufacturers. In fact, there are not so many true manufacturers. 90% of the entire market is produced in China, the rest is Korea, Turkey and some manufacturers from Europe. All the others just install ready-made boards in the case, on which they only put their logo.
Step 2
To find the manufacturer by chassis, open the lookup table. For example, follow the link https://master-tv.com/article/index.php to the "Matching Chassis and TV Models" section, select your TV brand from the list and look at the table. You can also use the list posted at https://shemabook.ru/component/content/article/1-latest-news/1082-shasy2.html to determine the TV chassis.
Step 3
Identify the chassis by the logo on the PCB. The manufacturer's logo is usually applied to it using white paint. For example, if it depicts something in the form of a rocket, against an oval background, it is Changhong. Find your logo on this image https://monitor.net.ru/forum/files/tcl_1_202.png
Step 4
Pay attention to the marking of the processor - it also indicates the firmware version. For example, the manufacturer Changhong uses a marking system in the CHххххххх or GDETxxxx-xx format. Judging by this brand, three main chassis options were massively imported into Russia: CN-18, CH-16 and CN-9. For Skyworth, a typical chassis name is a number / symbol / two numbers, for example, 5P60, 5S01. The second letter is the chip on the basis of which the chassis is made. The Konka manufacturer independently produces the chips, and its marking is done in the CKPxxxxx format. For example, this company includes the markings CKP1002S, CKP1001S and the like. There may also be a chassis manufactured by the Chinese company Eastkit. Its labeling has the following format: PAEXxxxx. Thus, it is quite easy to find out the chassis manufacturer from these data.
