http://www.google.com/search?q=LE40R88BD does find some interesting reading but only for those that have a hot solder iron on the bench.

The rest of us will call in and try for a one time free capacitor replacement and hope.

I have a Samsung LE32A446T1W LCD TV. It seem that when its cold it works for a couple of hours. But then, if i turn it off and try to turn it on again, It kind of loops in Stand By mode.
Replacing the famous capacitors did not help.
But if I unplug it and leave it for some hours It works fine again. I've read somewhere that behaviour like this could be due to som dried out soldering. If so, where? I've also read about an eeprom issue, but not if the TV start to work again. Would an eeprom reset itself if it get some time off?

My question is

Actually a few.

1. Were the caps showing the famous visual issues?
2. Was the set showing the famous symptom?
-> To this it seems the answer is no. The bad cap issue/symptom is it won't work when cold and works when it's warmed up.

3. Solder does not dry up. It can have "cold solder joints" which you can research to see what to look for.

But at this time we are well beyond user serviceable areas.
