So we just had the Samsung tech out to replace the board with the capacitors, but the TV (HLT-6187SAX/XAA) is still having issues. All 5 capacitors were swollen (bad), but replacing them didn't solve anything.
Basically, it takes a really long time (and many attempts) to turn it on when it is cold.
We turn it on, one of the green leds on the front blinks for a while, then it turns itself off after a couple of minutes. We do this several times (about 4-5 times I think) before the TV finally warms up and stays on, and we get a picture. We've thought about just leaving it running all the time, but I have a feeling that that will shorten the LED lifetimes, particularly the red one everyone talks about going out.
The Samsung contracted tech called it in after the capacitor replacement failed to fix the problem, and apparently he was told that sometimes the light engine is damaged by the failed capacitors, and it needs a new "light engine", which would only be refurbished at this point, and probably cost $1000 or more.
Anybody seen this problem, and have any idea what is really wrong, and if there's some cheaper part we can replace? We did love the picture on this TV, but it looks like it's dying.
