Re: Tc-55as680u steady blink
Your first hunch was right... It was 1 LED that was keeping the whole TV from working... I jumped it with a wire until the part comes in.
3rd row 3rd led... go figure.
Thanks so much for all you help...

Re: Tc-55as680u steady blink
here are the pics... All the service points on the boards check out... during the restart.... but the 12V going to main board turns off when the set turns off... so its only on momentarily... It also travels down to the t-con board (which was replaced)..also measure all the high voltage 74V to the LEDs - the big caps go to 170V 5.2 V consistant even after the flip off... Light flashes on and off and goes int the blinks which are actually 3.5 to 4sec between each but continuous...
the wires going to the main board are all close to zero...Leave a comment:

Re: Tc-55as680u steady blink
ok so a 2.5 second pause is a break... yeah i can understand this cause it seemed like a long pause....
so you think it may be this...?
1 blink STV 5v sense DG board
which would be which board? or which connection should I measure...
I am opening it up now and will send some pics...Last edited by phat34; 07-15-2016, 02:56 PM.Leave a comment:

Re: Tc-55as680u steady blink
ok will do and update thanksever
btw that blink chart only works on LED's that have a blink count.... this is just a steady blink every 2.5 seconds...
Just was looking for any ideas before i tore it apart again.Last edited by phat34; 07-15-2016, 05:08 AM.Leave a comment:

Re: Tc-55as680u steady blink
Is it common for 18 Month LED Lamps to burn out when you replace a T-CON Board on Sets?
What's the average lifespan of an LED lamp in TV sets?
oh just saying I could still use a link to a manual.. I did search on some sites for manuals I saw posted but have not found one for this model.Leave a comment:

Re: Tc-55as680u steady blink
Yes the T-CON was exactly the same and worked for a week or so...?
And if anyone has a link to the service manual -- I will open this bad boy up again and test the LED points...
If it's a led on one of the strips will it just not light or can it short out the whole strip and give this error?
The TV is only 18 months old... So I am thinking its the power supply board because we charged I-Pads from the USB ports all the time... I know now that that is not smart...Last edited by phat34; 07-14-2016, 12:09 PM.Leave a comment:

Re: Tc-55as680u steady blink
Does someone have a link to a service manual for this... I don't mind getting back in there and trying to find a solution... as long as I have some guidance.
When trying to turn it on relay sounds , back light flashes on momentarily and then I get the led flash every 2.5 seconds that just goes on and on.Last edited by phat34; 07-14-2016, 09:48 AM.Leave a comment:

Tc-55as680u steady blink
Hey what's up... I have a PANASONIC 55" LED / LCD TV Model # TC-55AS680U that I replaced the T-CON board on --- TV worked for 7 days than went out with steady flashing led.... continuous counted up to 50 a few times to make sure it was not the 1 - 14 led service display --- it's just a steady red blink once every 3 seconds.... I will keep reading in the meantime to see if I find a similar situation, but if anyone can let me know if this means a main board or power supply board, that would be great! -
