Samsung LE40R87BD LCD TV - relay clicking repeatedly but wont start

[sparky]

hi
there is one cap bulging change the 5 x 1000mf caps
should cure the fault 105deg 16v wkd make sure you
fit in the same polarity and careful with the soldering

You need to shop around for prices.
I do these for �70 all in so you can get it done cheaper but electronics repair is not DIY stuff despite what websites say,it's dangerous unlike computers etc.The repair should be carried out by an engineer qualified to city and guilds,onc,hnc or so not just someone who can solder.If the eeprom needs replacing and he screws up the main board for you you'll be looking for a board at about �150.
I paid over �300 to have a few roof tiles replaced 3 years ago,why ? because i can't do it myself,that's life.If it's dangerous leave it to the experts.

Hi Sparky

Photo enclosed with different capacitors, ones in red are the ones that seem to be bulging.

Would a 25v not be better than the 16v you suggested??

hi
sorry 25 volt wkd would be better changed the 3x and the other2
 but be careful like other engineers says!
 are you could end up scrapping tv

Hi Sparky

Will be replacing the 4 x 1000uf 10v to the 25v ones, not quite sure what you were trying to say in your earlier post "would be better changed the 3x and the other2"

The top 2 capaciters are fine and are the 25v ones,
The other 4 are the 10v ones and then the 1x smaller 220uf which for now I will leave.

Regards

hi
just change the caps with the red x

Hi Sparky

Am gonna push the boat out and replace the 4 x10v ones, if these are the inferior ones as most people say then its best to go down that route.

Thanks for all the help with this matter and when I get around to getting the capacitors and getting them put in I will let you know how everything went.

Thanks again

hi
d'nt forget to post wether fault is cured by changing caps
to help others

I will be posting when I get round to buying the correct ones, been looking on rs-onlines website and some vary on the ripple ( not sure if this does have any effect or not ), when I get this cleared up I will be buying some, I am not the quickest but I will get there and I will be posting to let you all know how it goes

[chips01]

Ok just a quick update. have now got the capacitors and hopefully will have them done tomorrow.

Will post again to let you know how it goes.

My advice is to let a tv engineer repair your lcd tv. I have seen an amateur destroy a tv before and I don't think your house insurance woukd pay out if a fire was the end result.
Remember there are high voltages inside,even in LCD tv's.
Just ask any firefihgter, who can warn you about tv's smouldering and the outcome.

Ok the capacitors have been changed now and the tv comes on fine without any problems.  I have noticed now however that switching from different sources there does seem to be a small fault, tv-dvd is fine but then going from dvd to another source it seems to freeze for a few seconds and then turns over ( not really mind about it that much ), also when I change the mode to movie the picture is very awful in the way that the background is grey and the main subjects on screen are made up of hundreds of different colours, almost dotty like ( if that makes sense ) again its not too much of a concern as at least I have the tv working again.

I was wandering if I should have got all the capacitors changed ( only changed 4...3 were faulty but all being the same type and voltage I thought it best to change them all )  I kept 3 original ones in there as 2 were of a higher voltage and they were fine and there was 1 smaller one which was a 220uhf not sure on voltage on this one though.  Would/could this smaller one be causing problems now that I have upped the voltage on the other 4?

Photo attached to show what I mean, and sorry for making this post a bit long

Also attached is photo of the tv in movie mode

if your lucky youve just corrupted the eprom,if your unlucky youve trashed the main signal pcb
but try a new eprom first.
its very important not to run these sets for very long with this psu fault (a long time is 15 seconds)
many customers leave them clicking away for hours hopeing they will start even after they have been told not to do this,causeing damage to the signal pcb.
you can set the software up manualy if you can get a set of paramaters,i have them writen down for a similar set which i can let you have but there may be some important differences.
hope this helps

The clicking has stopped with the new capacitors and all seems fine except as in my previous post regarding the picture on movie mode, surely if there was a fault with eprom or psu the picture would be bad on any setting??

[theo laird]

Daz is spot on. The service menu will be corrupt. This signal panel is used also with hardware and software modifications on plasma models as well as lcd, if they have gone corrupt to plasma settings there could be your problem. There are 21 separate adjustments for Wide/Movie mode alone. It is highly likely they will be needing reset after your PSU problem. You need a copy of all 10 pages of the settings to be sure, then compare yours with the default from the service manual copy.
