Facing TV Problems? Ask a TV Technician.
Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.
- What boards you have so far replaced in TV?
ah OK, 2 long and 5 short blink error code indicates panel 12V problem, main board detects that 12V isn't being sent to t-con board of display panel for some reason.
Please replug the connector (PD) that goes to main board from power supply board and also replug PL and LV connectors between main board and t-con board, this will refresh connections and it might help to resolve the issue.
If it doesn't fix the problem then either t-con or main board of TV will be replaced. Please reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
I wanted to briefly follow up with you and see how the info worked, and see if that accomplished what you were looking to do!
Please reply back here if there is additional questions.
