Did you order an ORIGINAL REPLACEMENT LAMP? There's lots of guys out there claiming to sell original lamps but there really not the original. For Samsung TVs (The majority of them) use Philips branded lamps. Check and make sure you lamp is a Philips lamp.

is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

Sounds like you've already gotten into the repairs. The three major things that fail on DLP are the bulb, the ballast and the color wheel. If your bulb is new and you aren't getting anywhere, replace the ballast, if that is still a no go, then move on to the color wheel. If replacing those three doesn't fix the problem, you will have to whip out the multimeter and start looking for problems on the PSB. You can get a ballast on ebay for about $100. Start there. The color wheel should be very freely moving. If something is grinding and hindering the movement at all, you need to replace it. That grinding may not seem like much but it is likely enough to keep the wheel from spinning at proper speeds. The sensor then kicks in and tells the brain that there is a problem and the brain keeps the ballast from firing the lamp.
Good luck.
