Samsung LE40R88BD Clicking Relay
Dang-it:
Hi, I hope you all don't mind me bringing this back up but I have to say a big thank you to all, this has been a very helpful and informative thread and now my R88 is back up and working once more. So OK it took over 2 hours of trying various combinations before it worked but hey, it's working so can't complain. I'd say though the only difference I employed from the usual
was to keep turning it on and off via the remote after about one second shorting the eeprom, on the fourth attempt it lit up and I had no need to go into the service menu, this of course was towards the end of the two hours(got fed up trying), so it's all there and working just fine, indeed it's been switched off at the mains and plugged back in a couple of times and it's still working just fine so thank you all once again, very helpful indeed, Andy.

Hi, a similar problem here. I got a LE40R84BX which showed the same well known symptoms: Only a clicking relay, no picture, no audio. First, I replaced 16 capacitors of the power supply, but that didn't make any difference. Since the eeprom reset was also unsuccessful, I replaced the eeprom with a new 24C256.
Now the TV is starting up and I am able to do a factory reset. Unfortunately the TV switches off after approx. 10 to 15 seconds and after a few more seconds, I turns on again.
Any suggestions, where to continue the troubleshooting?
Thanks
Stephan

I use to short pins 5 and 6 to chassis. Very hit and miss. I know keep a few blanks They are only a couple of quid on ebay not worth the hassle of shorting the pins. Couple of minutes to change a chip.

Samsung LE40R88BD Clicking Relay. Anyone having difficulties after replacing the defective psu caps should keep in mind that fitting a blank replacment eeprom(24lc256 or higher if you wish eg, 24lc512) will be a better repair.Also to replace this chip is easy,you just swamp all eight pins with molten solder & off it comes,then use solder braid to remove the excess solder.On switch on the set will probably trip 2-3 times while it collects the data from the flash memory.These ics are available from "CPC" in Preston for less than £1.Hope this is of help.
With Thanks Graham Richards
