Aime Lapierre : I like your videos they are very educational especially this one thanks you for the detailed diagnosis
Electronic Repair Service : Doing video's takes xtra time you don't get paid for, so thank you for sharing & showing. Good hunt to locate the fault - bad mosfets. Can I make a suggestion? If you could take the upside down part of the video and flip it (edit that part), it would be a lot easier to watch.
tyrone arendse : Thanks for the informative video friend
Joe Camilli : Thank you post this video. I have one of these PS go bad. Using you video as a guide I was able to ID the bad parts. Was able to cross reference the old parts with new ones at DigiKey. PS is working great agian....

In this video I show you potential fixes for your Samsung TV that powers up and turns on with back lights but has no picture. I would start with replacing the Tcon board and if that doesn't fix it then replace the main board if that still doesn't fix it then it is a bad panel which is not fixable.

Iam Richard : It’s not bad panel, it’s the led driver one of the ribbons is bad. On the left ribbon coming from the tcon , put a little masking tape covering about ten pins, and so on. This disables any of the connectors in the bad side of panel because these work paralel so you’re basically skipping one and the tv will be back working 100%
langaz35 : Thanks man! Exactly the same issue with a LG 64 inch TV. Came to the conclusion to scrap the panel as well. Hopefully can flip the main board and TCon online
Sonofgod Jesuschrist : THANK YOU FOR ALL THE TIME AND EFFORT I BOUGHT A BRAND NEW TV
Ashlee Walker : Thank you for this troubleshoot!!
Ralph Gore : Hello Chris, thanks for the video. I have a similar problem with dead black screen. Not sure what might be a real problem inside the TV. If the LED light is off, how to fix it?
