Tcon Repair Tips
Tcon repair tips
Repairing a Tcon (Timing Control) board can be a difficult and complex task that requires expertise and knowledge about electronics. However, here are some general tips that may be useful:
Identify the problem: Before attempting any repair, it's essential to identify the exact issue with the Tcon board. Check for any visible damage, such as burn marks, bulging or leaking capacitors, or loose connections.
Check the power supply: Ensure that the power supply is working correctly and providing the correct voltage to the Tcon board. Check the output voltage of the power supply with a multimeter.
Check the connections: Verify that all cables and connectors are properly seated and in good condition. Loose or corroded connections can cause issues with the Tcon board.
Replace faulty components: If you have identified any faulty components, such as capacitors or transistors, you can try to replace them with new ones of the same specifications.
Use the right tools: Repairing a Tcon board requires specialized tools such as a soldering iron, a multimeter, and an oscilloscope. Make sure you have the necessary tools before attempting any repairs.
Be cautious: Always exercise caution when working with electronics. Unplug the device from the power source and discharge any capacitors before beginning the repair process.
Seek professional help: If you're not confident in your ability to repair a Tcon board, it's best to seek professional help. Electronics repair technicians have the expertise and tools necessary to diagnose and fix the issue.
VCOM Operational Amp.
VCOM, short for "Virtual Common Mode", is a feature that can be found in certain operational amplifiers (op-amps). VCOM is designed to help maintain a stable reference voltage for the op-amp's input stage, even in the presence of common-mode voltage fluctuations.
In op-amps, the input stage typically consists of two differential input transistors, with their emitters connected to a common-mode voltage source. The differential voltage between the two input terminals is then amplified by the op-amp's gain stage.
However, if the common-mode voltage fluctuates, it can affect the accuracy and stability of the op-amp's output. This is where VCOM comes in. VCOM uses a feedback circuit to maintain a stable virtual ground voltage at the op-amp's input stage, which helps to minimize the impact of common-mode voltage fluctuations on the op-amp's performance.
Op-amps with VCOM are commonly used in applications that require high common-mode rejection, such as instrumentation amplifiers and data acquisition systems.

⭕️ شبکه " MOVIE 24" مهمان ماهواره ترکمنعالم شد
شبکه "Movie24" پس از حدود 4 سال قطع بودن، مجدداً در ماهواره ترکمنعالم احیاء شد؛
این شبکه بیش از 5سال پیش توسط میلاد عزیززاده(یکی از مدیران پروایدر نورتتلکام) در ماهواره یاهست روی آنتن رفت وشبکه بصورت کمپلت(همان اسم و همان جایگاه و همان پیج اینستا) تحویل آقای آرش م.ز داده شد،
اما بعد از مدتی آقای آرش نتوانست این شبکه را نگه دارد و مجبور به قطع آن شد تا اکنون که توانسته مجدداً آن را در ترکمنعالم احیا کند.
البته پیج قدیمی شبکه در دست میلاد عزیز زاده ماند و آقای آرش ناچار به بازکردن صفحه جدیدی در اینستاگرام شد:
Instagram.com/_u/Movie24ch
Movie 24
On TurkmenAlëm (Yahsat)
Freq: 10845 V 27500
این شبکه از هم اکنون با کیفیت SD و در کنار دهها شبکه سرگرمی دیگر بر روی فرکانس ذکر شده قابل دریافت است.
لازم به توضیح است شبکه "Movie24" جایگزین شبکه "ME2" شده است، و شبکه ME2 به جای شبکه Sepanj قابل دریافت میباشد.
