Just did one myself 3.3v rail capacitor. Diagnosed using hot and cold on capacitors to pinpoint problem. After replacing it worked and bad capacitor read correctly at 47uf but I guess had bad ESR. It wasn't bloated either. Can never trust an electrolytic like a politician.
Please provide a link to the store where you can buy these diodes that you insert instead of strips illuminating the matrices in LED TVs. Pozdrawiam z Polski.
Hi. I watch your videos with great interest I have a request. Could you ever make a video of electrolytic smd capacitors mounted on the first layer of the motherboard, and how you identify which is damaged and which is functional? Thank you for the videos and best regards.
Tevz bey emeğine sağlık . Kalitesiz kapasitör kullanılmış. Led sürücü den sonra led tamiri yaptınız. Acaba kaç yıl sonra led patlar. . Teşekkürler hocam.
@@mahmoudnaser453 because they are bloated, and first seen on the video. I known they are not the reasons why the driver is not working. If I dont changed it may viewers ask why?I hope you understand.
Please change all the led strips otherwise the same problem may occur soon (because other led bulbs life will be reduced so same problem will occur again soon) Thanks
Sir, a personal question? Are you a member of an IP Tribe? Just listened to the background conversations and heard some accents that sounds familiar. Thanks.
Is the back light 3 rows each 7 bulbs connected two rows in parallel and one in series? If all bulbs in series the voltage required is 21x6 volt= 126 but it lits up at 70V hence my doubt.
Your diagnosis bit confusing 1 St you said backlight not glowing & Measured backlight voltage is not boosting then why are you going to 12 volt & 5 volt lines instead of backlight section.
Sometimes addressing the visible issue, like a bloated capacitor, is the first step in troubleshooting. It's essential to fix any obvious problems before diving deeper into more complex or hidden ones. This can help prevent further damage and ensure a more thorough inspection of the system.
Thank you for the tutorial. I learned capacitors can also be a root problem too backlight issues. Keep up the good work.

3 to 4 years
Thank you sir ..
Nice information sir
Good sir
Good job..
Mr . Tevz you must first testing the led driver first when you measure the voltge
That is exactly what I did.
No,you first Chang tow capistane 470mf/16v&10v,I think so

Great tehc
I love this man...very smart
Thax alot
thank you sir
Love You sir🇧🇩🇧🇩🇧🇩🇧🇩
Please give me a link to buy single leds for backlight which you are using when strips not available
bL tester can be use to check the defective backlights
Please change all the led strips otherwise the same problem may occur soon (because other led bulbs life will be reduced so same problem will occur again soon) Thanks
good

hahaha hindi
👍👍👌👌
Sir, can you tell me what is the value/ marking of the rectifier diode? Because mine is burn out. Thank you!

they all connected in series, the LEDs are 3 volts
👍
🤟
Are these lights in series? Like Christmas tree lights? if one is bad it will disable the others?
You're right
I am from pakistan
Sir I need your WhatsApp number I am mechanics led tv
Helo Sir, does Sharp TV will light-up when the main board not connected ? Note : My TV has Power board and Main board separated.
No idea
Pleaae show your fork type testing probe in next video
fork probe? clip and high voltage probe all I have.
@@tevzTVTevatronics I am from India how can get it
why didnt use led tester
Multi tester can test it
Your diagnosis bit confusing
