40" Samsung LN-S4095D LCD with distorted blurred colors

by Sidney_s / February 19, 2010 10:44 AM PST

I have a 40" Samsung LN-S4095D (almost tree years old) and it has this problem with colors, for the last 1,5 year, that was intermitent at first, but now the problem is there all the time.
The colors are kind of blurred and over-saturated, amd all solid color images are blurred with other colors over (like in clouds on a blue sky there is a faint haze of pink on the clouds).
On faces there are glowing stains of white and any solid color image has a haze of other colors over it.
It is like this for any source and it is not a problem with cables or sources.
I opened up the back of the TV and checked the capacitors and everything is ok with them.
I think it might be either the Main PCB board or the T-con board.
I have to import these boards to Brazil, to try to fix it.
So, if I buy any of these boards I would not be able to return it in case it is not one of them.
So, as you can see, I am in a dilema of wich board to choose to try to fix the TV.
I don't wich one of these is more probably to be faulty for this kind of problem.
Is there anybody that had similar problem and can share the solution?

Can any Samsung HD-Tech give any sugestion based on the descripition of the problem.

Any suggestions please?

I can't offer part suggestions for the simple reason that if my diagnosis is wrong, then people "blame Samsung for a faulty diagnosis". I'd have to recommend that you have your unit inspected by a tech.

I have shown it to a repair tech here alrealdy and he don't know what is going on.

He made the same two guesses I did, that it is either the main Board or the T-Con board.

But because I have to import these boards (my TV was bought in US), so I am alone on this.

Samsung in Brazil washed thier hands even when the TV was under warranty (I had a different problem), saying they couldn't help me becuase it was a imported TV.

I will appreciate any suggestions even if it is only saying that for the type o problem my TV has (by description) the most likely part to be failling is this or that.

Great corporate response! Instead of "blam[ing] Samsung for a faulty diagnosis, I'll blame them for building inferior products that don't last outside the warranty. Indeed, we should expect more than three/four years service (I bought mine in October 2006). When Samsung makes products that are more than "good enough" to get them past the warranty period, I will buy their product again. Shame on you.
