Samsung LE40R88BD Clicking Relay

[sparky]

hi try this
Thanks all, it's now working. Owe you all - big time. This is as detailed as I can go ( after replacing 4 caps ). The critical part seems to be the delay ( see point 3 ), thanks to Mike for this ( my name's Mike - a lot them around ).

1. Short out the eeprom pins 5 & 6 ( the two legs with the resistors ).
2. Turn on the power.  - Instead of the usual noticeable relay click, you get a faint click, the backlight stays off, nothing else happens.
3. Wait around 1-2 secs ( anything longer than this NEVER seemed to work ).
4. Remove the short
5. Press info,menu,mute, then power - In that order individually, one at a time.
6. TV should come on with noise picture and the service menu.
7. Navigate to reset to go back to factory defaults and you're away....

Thanks,

I've been trying this for a little while now, the relay clicking has stopped but no picture as of yet. Does the picture come on as soon as you release the short on the eprom or after you have completed the sequence on the remote control?

Thanks again

I have just replied on another thread for the LE40R87D that has the same issues, it is over 2 years old, out of warranty and they have recognised a fault with them.
  I rang samsung today and they are repairing it free of charge, I only had to mention the clicking noises tryimg to start tv.

Hi, I am in the same boat as you were; can you clarify a point for me because this is really doing my head in. :wallbash:

On point 2 (below) it says turn on the power, does that mean plug in, or take out of standby?

cheers

Cheers again everybody - I was on the brink of giving in to Samsung....

Hi great-kev
It means plug in at mains. Bear in mind that sometimes it takes a lot of attempts with your shorting link and plugging in the mains, to coax the set to fire up with backlights so that you can proceed to the next step.
Regards
John.

Thanks for the quick reply John, just wanted to know I'm doing the right thing!

Also when I've released the short and press the remote sequence, i am not getting any acknowledgment on the TV of the key presses (usual led flash on the power button)

Should the backlight fire before i get to the remote sequence?

cheers
Kev

Hi again great-kev
After plugging in and then releasing the short, leave the set to do its start up process with the standby led flashing. Hopefully the backlight will fire up. If not, repeat the process until it does. Dont think pressing the on/off button on the remote makes much difference to the outcome. The time the short is present seems important, generally release it 1-2 seconds after plugging in.
Best of luck
John.

Seems to me its a lot easier to just change the eeprom..okay so I can solder and I've changed a few but at least the set works every time.

Hi there.

I also have a le40r88bd model and had the clicking noises with no power, no freeview, acid colours in movie mode, and anything connected to scart sockets wouls leave a picture trail, i developed a way to got the set to turn on easily instead of waiting ages for it to power up itself. which was to simply hold down the power button on the tv's panel until it powered up, this method usually took about 15 seconds. then i discovered that if i were to turn the tv to tuning channel 1 before i powered off it would restart 1st time if turned back on within a few hours of powering down.

any way i was fed up of all these silly procedures and rang a samsung repair centre who said £50 callout fee well i refused to pay someone my hard earnt cash to tell me my set was broke when i allready knew it was. so i turned to the internet and found this site after trying everything here like like replacing capacitors and shorting i still had no luck. as i could get into the service menu but resetting didnt change any of the root settings. so i got a copy of the service settings and manually went through every setting and noticed they were all messed up so i changed the settings to the recommended ones and DIDNT hit reset after i just turned tv off and back on. at last i the freeview was back online, movie mode was back to normal and picture trails had gone. powered it down and woke up this morning to a tv that turned on first time. i dont know if this info will solve some of your issues but thought it was only fair to post the method i used as the methods i allready saw on here were what got me started. i was about to skip the tv. cost of repair was £1.90 and an hours tinkering. Thanks guys

Hi, just letting you all know that samsung sent out an engineer, they couldn't repair it on site as the capacitors breaking had caused the micro processor to break, that was a Monday got it back on the Friday all working fine and courtesy of samsung

[panhead]

hi all , i had this fault and have replaced the nessacary caps . i now switch on and the unit fires up with a white band around 4 inches high at the bottom of the screen. has anybody had this fault before?

Hi folks,

There's a thought about goods being fit for purpose, where known problems allow shops to rectify F.O.C after normal guarantee periods have expired.

Know of some, admittedly not with budget gear, but worth having a go perhaps -  Chris.

I followed the advice on this forum today and managed to save my Samsung LE40R87BDX. (For those who do not know the R86, R87 and R88 models are technically the same except for some cosmetic differences). I definitely recommend replacing the capacitors mentioned in this thread as I believe the EEPROM issue is a result of these faulty capacitors. This is a bit of a regurgitation of the information already on this thread but is how I did it.
 The EEPROM chip is fairly easy to identify . It's on the underside of the main board (green board) has IC803 printed next to it along with EEPROM. If you look closely one of the corners of the chip will have a dot on it. This identifies the 'top' of the chip. The legs are numbered 1-4 running down the left hand side as you look down at it and then 5-8 on the right hand side running up the chip. In other words, in number order anti clockwise from 1. Therefore legs 5 & 6 are the bottom right two legs.
 Initially I raised the main board and attempted to short these two legs with a screwdriver and this did not work. Probably because it was very awkward to do and I maybe slipped of the legs but anyway after many attempts this DID NOT WORK for me. What DID WORK was to solder a length of wire approx 5 inches long to each of the legs so I could re seat the board and short them with ease.
 Now with everything back in place and screwed down correctly and my two wires freely available I shorted them.
 I then plugged the TV in at the mains and did a count of 1,2 then opened the wires. In my case there was a lack of a click then a faint couple of clicks. The screen was completely dead but the power LED was solid now and not flashing.
 I followed Mike's button selection of INFO, MENU, MUTE and then POWER on the controller.
 Give it a few seconds to come on. According to Mike's post you can expect to see noise on the screen and the service menu. I was impatient and pressed the power button a second time, switching the TV back off before it had a chance to turn on. I then pressed the POWER button again and the TV came on. It came on to the freeview NO SIGNAL screen. If you are anything like me you'll just be glad the screen has come back on. I tested it by hooking up my PS3 via component cable and all was good.
 I left the wires on the EEPROM chip and taped up the ends so they are there in case this ever happens again.
I hope I have been clear and that this is easy to follow. I am extremely grateful to everyone who contributed on this thread and just wanted to share my success story.
