Hey guys. This is my first post, so please be gentle! My Toshiba 40L1333b LED TV has sound but no picture. I used a flashlight in the dark and the picture is barely visible. It's about 1 year old.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Toshiba LED TV 40L1333b sound no picture
Perhaps you need to do some reading? There are more and more threads re led
tvs with no back light - weak point seems to be the led strings either burnt out
or a wire trapped and eventually shorting however it may not be a quick fix.
Try and learn some of the names of components on the board.
Pictures really are not clear enough- for trouble shooting they need to be clear enough for us to read the board part numbers
Here is a recent post - not yet solved.

Common issue with these Panels is the little connector blocks that link the Led strings break down and fail so you need to bridge them over with solid wire and then test the Leds.Last edited by ReeceyBurger123; 05-05-2016, 02:52 PM.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Maybe follow the thread, and watch the video I linked. Common issue with that chassis is the connections between the Leds breaking down causing no backlight.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.
