Have TV Questions? Ask a TV Technician
Hello, I'm Shahid and will be happy to assist you.
- Do you have multimeter and can check volts on circuit boards inside TV to troubleshoot the issue?
- Was TV dropped or screen hit by any hard thing while taking it off of wall mount or placing it some where?
These info will help to assist you further.
OK, please unplug the TV and remove connector SS11 from the SS board. Plug-in the TV and turn it on.
Is the power LED blinking 7 or 8 times now?

Thanks for the info. There are two boards located on left side of SC board calls SU and SD boards and one of them isn't working and causing the problem, please replug connectors between SC and SU/SD boards and again check, if problem persist then replace SU and SD boards that will help to resolve the problem. Please check following board supplier link to get required board..
