No the blinks six times then nothing for about 10 seconds then cycle repeats itself.
Expert:  Anthony_Infotech replied 1 year ago.

OK these sets do not have a blink code hopefully you should have disconnected from wall-power wited 5 mins then re-plugged back in I guess you have done that so that leaves a bad main-board, a visual check of the power-board is also carried out, can you do this work yourself?I will provide all the necessary info for that let me know please, its not as hard as you think the boards are plug in

If you are not comfortable with that then you will need a tech www.tvrepairpros.com will locate a tech in your area.

What board is what?
Expert:  Anthony_Infotech replied 1 year ago.

Are you considering doing the work?if so you need to get the back off the set and initially let me know the condition of the capacitors on the power-board you trace the power-cord to the power-board the capacitors look like this graphic <<click

You are looking for any of them ballooning/raised domed tops/leaking

This is the first check in an on going procedure that may mean replacing the main-board that is the one with all the AV inputs on

Let me know please

I already have the back off there are no bad caps
Expert:  Anthony_Infotech replied 1 year ago.

Locate the main-board that's the one with all the AV connectors on, unplug and unscrew the board from the chassis, remove the board ,carefully examine the board for its part number usually found on a sticky label on the board or etched on the board, (you may need to go through a few codes before you find the right number)when you get the part-number try www.shopjimmy.com first, if they don't have it google the part-number to locate a supplier, its the reverse to fit plug in and switch on TV (plug and play).

The main-board has a hardware/firmware failure the only option is to replace it.

Let me know if you need more info
