Samsung LE40R88BD Clicking Relay

[Turnip]

Hi Sparky, and thanks,

Was about to paddle from Norfolk with just 3 caps, some nifty bottles and a bit of wire,

Well, for that sort'a cash even a tight Brummie might venture - suggest Liverpool rather than Yarmouth, as from here, you have to get around the corner - either end - Chris.

Same problem here!! but mine is a Samsung ps42Q96HDX Replaced all the capicitors as suggested, did not work, reset the EPROM chip, worked fine for 30 min or so and then switched off, and started clicking again. Turned the TV off at the mains for 10 min, switched on works for couple of mins and then starts clicking again. Any suggestions greatly appreciated!

How to find pin 1 on an ic:, if you can’t see the dot for pin1 either on the ic or the board (on the Samsung 40” lcd there’s an arrow) in 100% of cases if you look at the writing and can read it then pin 1 will be bottom left therefor pin 5 and 6 will be the top right ones.
A ps42q96hd is a Plasma, it isn’t known for having cap problems, it is however fantastically common to have either dd.’s on the psu (casing clicking) or for a fet or both fets to blow (causing no clicking).

Shorting an eeprom won’t always work and if it does may leave some odd faults on the set, if it does bring it out of stand by then it was the cause of the problem. If you’re unsure if it was corrupt, go into service mode and check the time the panel has run, if it is a low number then there’s been a problem in the past that’s caused the corruption

Thanks for the great info on this site. I could not find a busted capacitor, so shorted the eprom for 1 second. Worked first time!
However, TV stopped working again some time later, so called Samsung. THEY ARE SENDING ENGINEER OUT F.O.C. to look at my 3 year old set!
So give them a try first I suggest.
I have attached (I hope) a photo of the eprom in question to help others find it.

On the SP02 Version of the power supply

I thought I would share these lovely photos of the caps

I want to ask which caps are best to replace out of these lot?

all of them?

also is it best to replace them all with the exact same ratings? or different ratings to make sure they don`t go faulty again?

Nice to see this thread back..we going for the record number of posters?

I tried multiple times to reset the eeprom with a small screwdriver but wasn't making good contact and found solder wire of right size made a good contact just pushed against the 5 and 6 pins. Still took a few goes but eventually must have got time held against the pins right and the tv came on and just needed tuning, so it does seem that by multiple tries it will eventually work. I found it tricky soldering wires to the pins but just a length of solder wire held across the pins does work.

Just wanted to make the effort to thank those involved in this thread. 

I'd spotted the blown capacitors myself and replaced them, but the clicking continued, and I was on the verge of assuming that something further down had blown as well.

Advice on resetting the eeprom worked exactly as described - took about fifty attempts over an hour or so, but eventually the backlight popped on and I got into the service menu. I might have given up earlier had the advice on this topic not been so specific.

For resetting the eeprom, I used long wires and soldered them to the legs of the eeprom chip. From the discussion on the board it sounded like they would be super tiny connections, but they weren't all that scary when I got the AV board over. Needed to get the magnifying glass out, but that's more to do with my eyes! :)

Anyhow, thanks all. I don't know if the fix will last, but this ressurection was a fun little project.

Hi all
I have a ps50b850y1fxxs with the same clicking relay problem. But I can't see any signs of capacitor failing. Also when it did work, it often increased the volume by itself so perhaps my issue is failing buttons on the tv? would the eprom short be worth trying without replacing the capacitors? if so which one and which pins?
Please Help!
Regards
John.

 :sign0144:many thanks to all, fix worked a treat. replaced the usual suspects (bulging caps)only to discover the clicking relay was'nt cured, found this thread, shorted eeprom as described in at least 20 posts in thread and voila, tv now working a treat, is this some sort of witchcraft?, anyway many thanks to the sole who first discovered this magic spell.

This tread helped me repair a LE40R86BD.

When reading this tread I got the impression that most of you had okey picture after cap change. My picture was so bad so I suspected I had more severe problems.

My story:

1. Tv was clicking - backlight came on for a couple of seconds - no picture
2. I replaced 7 caps in the 5-12v area on the power supply board.
3. No change in behaviour
4. Did eeprom reset by shorting pin 5,6 as described.
5. TV came on and displayed a rainbow of vertical lines over the entire screen.
6 I suspected the eeprom was okey and that I had more severe problems on the t-con board.
7. Thought I anyway should give it  a try with eeprom change and I fitted an Microchip 24LC256 (blank from store)
8. TV powered up and is now working perfectly!

I can confirm that Microchip 24LC256 eeprom is working fine if you can't find original atmel version.
