Re: Samsung LE32N73BD - 2 seconds to black
samsungs are quite good quality,but they are a pig to fix,i cringe sometimes when i get one,especially if there are main board issues,.
samsung like to keep things close to the there chest,had a dig around the net,there is a couple of people trying to just get the main board and havent succeded,and this is going back to november2011.
the closest thing i could find relating to your problem,was that they disconnected the panel,i assume from the t-con,booted up the tv,and it seemed to re-write the eeprom,and it worked for a while,then went back to normalfixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!

Re: Samsung LE32N73BD - 2 seconds to black
Okay, forced the B/L on. Now this is interesting. I get a full frame of analogue snow, but then it fades to black (T-con power cut.) After it warms up, I sometimes get no frame at all, or half/quarter frame. So, something is warming up and going out of spec, perhaps some reset IC or protection detect.
I already disconnected the T-con to no effect but I will try again.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung LE32N73BD - 2 seconds to black
Here's something interesting. Didn't notice this before, but SDA line flurries with activity just BEFORE the picture shows, not after. Picture goes out without any SDA activity...
Only reset IC is for sub-micom but it's okay, tested with scope.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

by eigmaHi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.
Service manual: https://www.electronica-pt.com/esque...is-u8la-71272/
SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

by MgiffuneI have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
