Replaced failed lamp but tv still thinks lamp is bad. Tried reset already.
I can't get it to work after replacing the bad lamp with a brand new one. I followed all the instructions in the manual exactly and it was a simple procedure. No picture/no sound/then red light comes on as tv shuts itself off. Reset did not help.

Re: Replaced failed lamp but tv still thinks lamp is bad....
Turn on the set and let it shut down. push in the Menu and Device (or input, I don't have a schematic in front of me) buttons on the front of the set at the same time and hold until the green light starts flashing. Then release.
There will be two different sets of flashes, such as, 3 and 6. The code 12 means the set is opperating fine. The other codes will tell you what part of the set needs repaired.
Also, remove the bulb and check the ballast connection to the bulb. I find the connection for the bulb bent over when a customer replaces the lamp sometimes.
Let me know what you find and we can go from there.

Have you tried replacing the lamp? If not, I would start there. Also, after replacing the lamp, make sure that the lamp door gets put back on or it will not come on. There is a safety switch that won't allow the tv to come on when that door is off. If you have already replaced the lamp w/ a new one and you are getting the same problem, then the problem could either be on the lamp ballast, or power supply board. Some tests would have to be made by a tech to determine exactly where the problem is. It sure does sound like a bad lamp though.
Have you reseted the lamp timer of your tv? if not, you should do it, because it's just adding more and more hours to it to the ones it already had and it's indicating the tv that the lamp is going out, reset the lamp timer and you should be fine, if not, it's probable you might have a defective ballast which are not expensive, they're way cheaper than a lamp, they're running around 70 dlls
Chances are the lamp is not bad. Is the lamp door reseated properly? The is an interlock on that door that must be activated in order for the set to turn on. If the unit was woking before the lamp went out this may be the problem
It is b.s. but it's not only samsung that have poor reliability. At least they have some customer service. Some new brands are a nightmare. I would suggest changing the ballast first, and if that doesn't do it, you're probably looking at a dmd board which is very expensive. Only other thing I can say is to try removing and reseating the lamp switch again. Also listen for the color wheel to start up a few seconds after you push power on. Color wheel is started by dmd board, lamp is driven by ballast.
