Tv seems to be fine except it is not allowing a signal to come in.
Hi @wansorl , If the problem only occurs when using HDMI inputs and not any other input type then there may be a problem with the HDMI IC switch Here’s an image of the No video (HDMI) troubleshooting flowchart, taken from p.68 of the service manual for the TV that may help in finding out what the problem is.
(click on image to enlarge for better viewing). The service manual is a bit awkward to use online as you have to enter the required page number or click on the up arrow in the box below the document box if you want to go to the next page in the manual. You can download the manual but you have to register with the website. Hopefully a start
