Tevz sir You are great and expert But we are mostly learner so Now start with the besic power sequence of power supply and motherboard testing step by step Thanks sir
One problem dc buck converter solved another problem is the panel. That's is how the electronic works. Sometimes we try our best to make it works and sometimes it can't be done.i learn something new. And I will keep watching you always because I wamt to learn. Good job 👍 ❤️
and cutting the CKV lines are also not helpings, thank you I've learned something thank you for the time put together to make an upload this video we appreciate so much
Good job sir. 😊 thank you sir to sharing like this usefully informations.❤ But I have one note about the copybook's spring. It's iron so maybe doing short circuit with the another pieces. I am fallowing you always because you are a genius and master.❤ Thank you again with my love and respect .
Very good video, congratulations. I'm from Brazil and always follow your videos. Please, can you tell me the reference of this converter that you used in the video? Thank you very much in advance!!
I came to this channel because i was interested in repairing televisions at the moment, but it became boring for me to watch it all the time, i need something new (devices), think about it. 😊
Hi Tez , ...this means the two sides of ckv signal entry painel are defective? a short kiler in the ckv lines dont solve the problem? and increase or decrease vgh voltage? Thanks for your valuable info. Great video.
Ive had the similar issues with a hisense tv that was stuck between standby and trying to turn on.. It was the 1118 dc to dc. Its still held up three months after being collected.
Hello tevz,have one question not on this video from the backlight section my question is why 10 pin backlight drive ic give bb sound to the positive pin of backlight at standy by mode?
I'm trying to repair a Seiki se39he02 that has standby but no blue light. No 12v on LVDS output at the connector on the board. This is a single board TV. Is it necessary to get FB from the panel for the TV to turn on? The switching transistor has 12.5v on both gate & source but 0v on drain. There is a transistor next to the switching transistor that is supplying the 12.5v to the gate of the switching transistor. Does this seem right? I expected a much lower voltage on the gate of the switching transistor, am I wrong? I'm suspecting panel is bad, I tested it with a T80s panel tester and it would not turn on.
@@tevzTVTevatronics The TV will not turn on, there is no voltage to the LVDS. The board will only go into standby (red led on - blue when TV on)). The drain on the switching transistor goes directly to the LDVS connector but has 0v, even though there is 12.5v on both the source & gate. I wasn't sure if this particular TV required feedback from the panel to turn on LDVS. I wasn't why sure there wasn't 12v output on the drain since it connects directly to the LVDS connector. Thank you for the reply.
Am John Linus, am having issue with Samsung TV Model No:LE40A656A. It have standby light on but not turning on the screen, please what can I do to it so it can work.

Tevz sir
You are great and expert
But we are mostly learner so
Now start with the besic power sequence of power supply and motherboard testing step by step
Thanks sir
I like the honesty bro Tevz. Thanks for sharing
Always
Hi tevz,i am from India, i likes your video, video is informative and knowledgeable.
Thank you
Thanks and welcome

This guy is a mind of information. He's the best and certainly not boaring.
All the best x
As often happened, finally we learnt something new...thank s bro for share your knowledge..
Iam TV technician your videos are the best Tevz I always learn on your knowledge ignore those who a saying u a boring now keep posting Mr u a d best
thanks
Hi Tevz,i am from South Africa,i enjoy all your videos,keep uploading,great work,much appreciated 👍👍👍👍👍
Glad you like them!
Nice job Tevz. You can win them all. But it was still informative thank you.
and cutting the CKV lines are also not helpings, thank you I've learned something thank you for the time put together to make an upload this video we appreciate so much
Very helpful knowledge sirji, thanks a lot❤
Keep watching
عالی ممنون
Hello Tevz, I am happy to contribute and I appreciate your sharing and hope that you will continue to share many videos, thank you!
Thanks for joining as a member. Yes, I will continue to share more videos.
Good job sir. 😊

But I have one note about the copybook's spring. It's iron so maybe doing short circuit with the another pieces.
I am fallowing you always because you are a genius and master.❤
Thank you again with my love and respect .
Ótimo serviço, realmente esses conversores de tensão ajudam muito mas infelizmente os painéis de LCD estão cada dia piores.
Good Job Sir
Good work bro❤
❤❤❤ thank you sir❤❤❤
good work
good
Good
👏👏👏 great video 👊👊
Thanks sir
Good luck Next video 😊

Hello Tevz. I wonder why it is not easy to replace the dc to dc regulator chip ? Is it because of the aluminum caps or for other reasons ?
No dc to dc IC available.yes also the aluminun cap.
Ive had the similar issues with a hisense tv that was stuck between standby and trying to turn on..
It was the 1118 dc to dc.
Its still held up three months after being collected.
Hi Sir ,,Good wishes to u and your channel
Just a small question ...is it possible to install, Boost module ,to ,plasma tv power supply. .
yes it defends what you want to boost
@@tevzTVTevatronics ,to boost ,340V dc to 390 v dc
gaining everyday
👍👍👍👍
tank u
А есть ли у вас ремонт индукционных панелей?
Hi we can use the ic regulated 7805? 😊
7805 is a linear regulator, its genarate heat in a high amp load, not like a dc to dc converter.
❤❤❤❤❤❤
Hello tevz,have one question not on this video from the backlight section my question is why 10 pin backlight drive ic give bb sound to the positive pin of backlight at standy by mode?
I'm sorry, I don't seem to get your question.

I expected a much lower voltage on the gate of the switching transistor, am I wrong? I'm suspecting panel is bad, I tested it with a T80s panel tester and it would not turn on.
Could you make sure the tv is turning on? 12.5 volts to the gate and when it's turned on the source is also switch to 12.5 volts.

😂thanks sir
Several times when this dc-dc converter fail, there are some more wrong.
Man try even other appliances
Great work Ankel Tevs👌🏾... Watching from South Africa... Can i please have your whatsapp digits so i can video call you when im stuck. Please 🙏🏾
