I have a 40" Samsung LCD that I bought about 4 years ago and still love, but lately it's been giving me scares due to how slowly it warms up. If it's off overnight, when I turn it on the warm-up process takes a lot longer than it used to -- I don't hear the "click" and the picture for whatever input it was last set to for about 6 seconds or so after turning it on. Once it's been on for a while, I can turn it off and on with no problems or lag, so it only seems to happen after it's off and cold for a while.
I'm assuming it's starting to fade, which sucks, since I really don't have the money to replace it. So what is the best way to keep it alive as long as possible? Should I still be turning it on and off as I normally do, or should I just leave the TV on constantly?
I believe you have the Samsung capacitor problem.
Call Samsung and see if your model qualifies for a free fix.
