Hi all,

I found this site after doing a google search and have found some interesting info.

Basically i have a Samsung LE40R88BD which wont power on, just keeps trying to switch itself on then off with a clicking sound, i replace all 6 capacitors to no avail.

After reading on here the eeprom can become corrupted, i have found the eeprom 246C256BN.

I'm having trouble finding pin 5 and 6 to short as there are no numbers on the eeprom itself?

Any help appreciated

Thanks

Adrian

Hi John and RB
Set now up and running. It was a case of a corrupted eeprom. Thanks John for the info.
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.                                          Thanks again tv john for the information.

Hi Sparky.

Thanks for the reply, yes i found that post after i had trouble locating pin 5 & 6, anyway i think i used the right 2, the 2 pins i shorted were leading up to a 101ohm, i also used a small screwdriver to short but weren't sure how long to keep shorting for, so as soon as the tv was switched on i removed the screwdriver.

Hi Guys,

Just wanted to a say a big thank you for this thread. Just followed it and fixed my TV  clap. I had all the caps replaced and I was a tad annoyed that it didn't work. Just spent a good 2 hours trying this out and suddenly it sparked into life.


AdyAde you've got the right 2 pins (beside the com interface as said before) just keep trying. It took a while for it to kick in on mine.

This is why I love the Internet.

Thanks again.

How did you short yours mate, and how long did you keep them shorted for? Can you tell me what you actually done?

Also if anyone is local to london middlesex and wants to earn some beer tokens by doing this for me it will be appreciated

I didn't fancy my chances on soldering something so small so I used a small flat head screw driver with a really long handle.

I unscrewed the board and had it angled so that I could see the other side of the chip as the pins are facing away from you when it's in place.

I had to have the screw drivee on the pins then plug in the TV and then switch it on with the remote. After a couple of seconds the screen came on.

I was a bit mad last night and wanted it fixed so it wasn't the best planned job.

With my TV as soon as it's plugged in it switches itself on & off, i have no control over the remote or buttons on the tv itself  dubbio

Yeah that's what mine was doing the first 20 or so times but once in seemed to make a slightly different noise and that's when it worked.

It's was a pretty tricky balancing act as the pins are so small and the board in hanging loose.
