TV red light blinck 6 time and logo shows but tv not power on

@praveenparate the 6 blink code on this model is a backlight error. It could be ( most likely is) the backlight strips. You have not told us what it does once the logo shows up. Sometimes you can bypass the error code and see if your TV still comes on. That also give you an opportunity to see if all the backlight LED are working. If some have failed you will get a 6 blink error.

We will have to see your boards to help you out further with that. Unplug your TV and take the back cover off (do not touch anything). Now take some well focused pictures of your boards. Post those with your Questions. We will need to see the connectors as well. Bilder zu einer vorhandenen Frage hinzufügen
