Hi Guys,

Got a Samsung LE32S73BDX/XEU which when plugged in is flashing the red LED in the following sequence;

solid for 3 seconds then 1-1-1-1 <2 seconds> 1-1-1-1 <2 seconds> - just loops

PSU in this is BN96-03775A

Anyone seen this before or know the issue?

Thanks,

Mark

Hi,

On visual inspection all the caps and components on the PSU look fine.

Does it need a new eeprom - I've read some posts about Samsung eeproms needing to be reset after repair by shorting some pins?

you can try it find the eeprom on the back of the board it'll be numbered 24c.... something or another usually an 8 pin rather small chip, the dot signifies pin 1 count along to pins 5 and 6 . solder on a wire to both these pins and join the wires . reassemble the set and turn on. The set won't actually boot up at this point. Remove the wires reassemble and turn on as normal . If your lucky this might fix it
Good luck !

Taken from a thread by " Contrast John " so thanks to him :
On this model the eeprom in question is IC 1803 (24C256) 8 pin smd and is located on the underside of the main board near the common interface. The clock and data pins are pins 5 and 6 and are identifiable by the 100 ohm smd resistors connected to each of them. Fit a shorting link (on long wires) between the pins. Reassemble the chassis. Switch on and then remove the short. Bring the set out of standby.
