Samsung LE40R88BD Clicking Relay

<< < (30/30)

LightsOut:
Thanks, I took your advice. Ordered a new EEPROM and got it today. Got to work on it immediately. I'm pretty much a newb to soldering, but I managed to both get the old one off and the new on eventually. Thought it looked pretty decent too, so I put everything together and powered up.

Faint click and the TV turns on! Just as I'm dancing my victory dance though, it turns back off again. And then on again by itself, it's on for about 30s, and then off again. Repeat. I try starting with the service menu sequence but same thing, while the service menu is open it goes to standby after about 30s and then on again. Tried with no input, with HDMI and with the antenna. No change.

Any idea on what could be wrong? It's definitely not unthinkable that I botched the soldering somehow... I'm really hoping that's not the case though.

Could it be some setting or initialization needed for the EEPROM that causes it to turn off?

Hi,

Apologies for bringing up this old thread but just wondering if anyone can help.

I've got two LE40R87BD's on my bench, both having had the same fault (clicking) and both have had all the 2200uF and 1000uF caps replaced - no change - still clicking.

So I've soldered the requisite wires to the EEPROM and tried the shorting process.  No luck so far.  I've tried shorting, plugging in, then leaving the short on for anything from 0 to 20 seconds, removing it and then trying to power up.  When I do, the TV clicks as it would, I use the power button on the set, you even get the slight beep that sounds like it's happy.  However, the light stays solid and the set never gets past this stage. 

Powering up without the short puts be back to square 1 with the clicking relays.

Can I confirm the process:

1. Short pins 5&6.
2. Plug in set.
3. After 1-2 seconds, remove the short.
4. Press Info > Menu > Mute  > Power (or just power - or just press button on front of TV) - How long should the set take to come on at this stage if sucessful?
5. You're now in the service menu (the bit I cant get to).

I've also see other variants of the procedure, involving applying the short, plugging in, removing the short after 1 second, unplugging, then plugging back in - this doesnt get me anywhere.

Thoughts?  I'm assuming it's something to do with the process as it's exactly the same on both sets.

sparky:
Try replacing eeprom

Frobius:
Yeah, that's pretty much my next step.  Just thought it was odd that both sets are in exactly the same state.

They're the 24L256 on this board right? I take it putting a clean EEPROM in forces the set to reflash it, rather than trying to trick it onto doing the same as per the short and power process?

Here's hoping!
