Hi please start a series on oled tv, they are the obvious future....
Thanks for everything you're doing....
Don't stop videos and education sharing please 🙏🏻🙏🏻🙏🏻🙏🏻
Superb channel!
I don't get why the double image problem can be repaired by just cutting or taping the CKV & CKVB line (usually there are a pair of them, I've done that too myself).
Still don't get it why do manufacturers give a pair of them, where it can obviously work with just 1 line. I hope this channel can explain my curiosity.

@@elearningélectronique aaahhh, I see it clearly now! It is because the larger display uses dual side driving, right?
When you cut one you will lose resolution
Muito bom Brasil.. 🔝🔝
Thank you very much. New subscriber here
Hello, hope you are fine. Can you plz make a video about xao vltage and what the difference between xao and 3.3 volt as both have same voltage
Long time go to see your new video. Can you make a video about the design and structure of both source and gate cof like if we dont know gate test point how can we find then. There is a scheme of every cof like rx signals always come in the center then voltge beside then then gama volt etc can you elaborate these things? Best wishes thanks
Bonjour, j'ai une LG OLED55B7V avec un trait vertical en couleur vert très fin et l'alimentation se met en sécurité en stand-by. J'aimerais savoir si le panel est hors de cause et c'est où que je dois chercher moi même étant passionné de réparation ? Merci
Please explain HAVDD what is work Please
Sir put daily videos. or weekly twice
I need your help
Hi' Sir just asking there's anyway to repair double image nit using tape method directly to panel repair even don't have lcd panel repair laser
best regards to you I'm also a tech. from Philippines
to my knowledge the use of the method with the tape is done only if the LCD is connected to a separate TCON board
@@elearningélectronique
yes common temporary repair using tape method because the shortage TFT signal is blocking and only one side ang working hope soon both of us we have lcd panel repair for much better repair for panel congrats to all your video sir God-bless
Sir CKV CLK shorting explain
Nice video but i want to add one thing, horizontal line can be reparable by replacing cof.
Yes, when the gate driver is visible the replacement can be done with a special machine. After that it depends on the cost of the repair.
bonjour, merci pour votre travail, j'ai une TV sharp lc-55 ucf8372es avec 2 lignes horizontales de 1 mm à penne visible, les gats driver ne sont pas visibles et j'ai déjà changé la carte-mère . je voudrais savoir si cette réparation est humainement possible .
encore merci pour vos vidéos
Bonjour, la panne est liée au Gate driver. Malheureusement si ce dernier est construit à l'intérieur de l'écran, il n'y a pas de réparation possible hormis le changement d'écran.
C'est bien ce que je pensais merci beaucoup
What is the solution? Any defect of the components that can be replaced instead of the screen panel?
in the first and third case there is no other alternative than to change the panel. On the other hand, in the second case, the defect is also due to the panel but there is a trick that allows you to correct the anomaly by cutting certain signals from the TCON card such as CKV, CKVB, etc...
Where have you lost Sir,?
Is that repairable?
The 3 televisions in this video have a screen defect. By changing the screen the repair is possible but at what cost. In the case of the screen with a double image, we can correct the defect by removing some signals from the TCON board.
@@elearningélectronique nice thank you for your info
Très désagréable quand cela arrive. Alors le remède c'est quoi?
Seulement dans le cas d'une double image, on peut bidouiller la carte TCON. Dans les autres cas, remplacement par un écran neuf ou achat d'un nouveau téléviseur.
السلام عليكم ورحمة الله وبركاته..أين النشاط
