Re: Samsung LE40R87BD LCD TV - relay clicking repeatedly but wont start
Needs an EEPROM reset, probably. There's info on this forum about jumpering pins 5 and 6 to accomplish the reset.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -
Re: Samsung LE40R87BD LCD TV - relay clicking repeatedly but wont start
this may help try at your own risk!!! found on another forum im a member of
For anyone with the same problem the procedure is as follows.
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. Now access the service mode as follows-
Using the remote control, switch to standby, press info, menu, mute and power. The set should start and display the service menu. Using scroll keys select item 8 and enter by scrolling right. Select "tuner" and set to auto. Revert to previous screen by pressing menu. Now scroll to "reset" and enter by scrolling right. The set will revert to standby. Power back on and tune in stations.Comment

As above but I found the time from powering on to removing the pin short is critical, I found it to be at exactly 1 second, good luck.Comment

Hi All,
First time posting here ... my name is Kevin but my friends call me Journey.
I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again.... -
