Re: possible red blinking light code, no power on samsung led tv
Check out this video same exact model code I have and same symptoms with the lights flash sequence, the fix in the video was a new led backlight part, one of the led's was burnt. Does one single burnt led cause it to not turn on?

Connector CNM803A.
The exposed pins on top are ODD number pins, the EVEN number pins are on the bottom side of the board. The white triangle is pin 1.
The list of the pin names are printed on the board.Leave a comment:

Re: possible red blinking light code, no power on samsung led tv
Sorry the tv has to be plugged in and with the red front lights flashing right? btw the picture you posted is not the board i have not sure if your helping someone else and you thought I was them.
In the picture you gave me I see a similar connector on this board but it doesn't say cn1 says another number and in writing it has voltage readings of 1,3,5,7 etc pins it should be reading Im assuming, nothing that says stb like you said.Last edited by pctektgg; 04-22-2015, 07:11 PM.Leave a comment:

Re: possible red blinking light code, no power on samsung led tv
Well we will go through diagnosis of the PSU first anyway.
As to testing fuses you would use ohm setting and check by testing across the fuse, >1ohm bad and <1ohm a good fuse.
Ok set your DMM to DCV and test each pin on connector CN1. List the results like this :
STB - 0v
5vS - 5v
etc

Sorry forgot to say, Black probe to chassis (screw will do) and red probe to each pin in turnLeave a comment:

Re: possible red blinking light code, no power on samsung led tv
Ok doing that now thanks....
heres the pictures there's 2 each for the power and main board, and one for that tcon cable I think that's what its called.
Also got a question about fuses I see typically in tvs like this those cartridge white ceramic type fuses like this power board has how would you know if they are bad it will have a burnt black appearance to it right? It wont be mighty white right? ThanksLast edited by pctektgg; 04-22-2015, 06:21 PM.Leave a comment:

possible red blinking light code, no power on samsung led tv
I have a samsung led model un40d6000sfxza, that as of last night it simply turn off on its own and now it has no power and seems likes its trying to tell me something with blinking red light code.
The sequence goes like this: on, on, very slight pause, on, on, very slight pause, on, on, very slight pause, on, on, very slight pause, on, on, after this 10th count it goes to a longer pause like its starting all over with the 2 at a time blinks sequence up to 10 counts again and starts all over.
I removed back panel and visually the power board looks good, I see no burnt components, no leaking/bulging caps but thats all I currently know what to do. Im not a tv tech but I can solder and swap boards and take tv's and electronics apart just not alot experience in electronics in terms of testing parts with a meter and such. I do have a volt meter btw.
But with directions from someone maybe I can follow if told how too. Anyone know what the blinking lights mean or know whats up? thanksLast edited by pctektgg; 04-22-2015, 06:05 PM.Tags: None

by Fergal22Hi,
I have the above tv that just shows a red light blinking twice 5 times, i have taken the back off and all the capacitors seem ok,
When i disconnect the mainboard from the PSU all the led's light up blinking fast but as soon as i reconnect the mainboard back to the power supply i get the red light blinking again twice 5 times,
I have attached pictures of the Mainboard, PSU and a small video (zipped) showing what happens when i disconnect the lead from the psu
Any help would be appreciated... -
by norbiszokeHello,

Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.

by 3DDDHello, I have a Samsung UE46D6100. It cannot be turned on, only the red status LED flashes, the power supply part bn44-00458a gives an output of 5V(A), it is probably functional. I don't know where to look for the error, according to the video it should be a faulty mosfet. I found a mosfet marked WAAH, I don't know what it is. Can anyone help me?...2 Photos02-20-2025, 12:51 PM
