Have TV Questions? Ask a TV Technician
Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it.
- Could you please get me the model number written on back cover of TV?
OK, take your time.
Thanks, ***** ***** sent me phone call offer which would cost you $26 extra, please confirm you want phone call assistance or if you prefer to troubleshoot here in text chat.
Yes, typing the info for you that takes couple of more minutes.
OK, power light on TV flashes twice pauses then flashes five more times quickly is an error code that indicates Panel 12V supply failure, it means t-con board isn't getting 12V supply or t-con board isn't working, possible causes are either power supply board isn't sending out 12V to t-con board OR LVDS cable between t-con board and main board is misaligned or has got bad contacts OR t-con board itself has been failed and causing the problem.
You would need to remove back cover of TV to access inside. Reconnect LVDS flat ribbon cable between t-con and main board. If problem persist then check 12V at t-con board with multimeter, if volts appear even for a second then replace t-con board. Please check with following board supplier to get replacement t-con board if you have plan to do-it-yourself..
