I got help from you guys earlier this week but I still have a problem. I was told my problem might be the lamp so I ordered one and put it in. Everything was fine for about 10 minutes, but then the TV's color went all weird and I couldn't shut the set off with it's controls (remote or the button on front). The set is only 3 years old and is a Samsung HLP4663W. Is it the color wheel like somebody else suggested and if so, is that expensive to replace and can i do it? Help!!!
I still can't believe that samsung is not even willing to recall peoples color wheels when almost all customers have been experiencing the same problems from all the reviews i been reading. I have the same TV. and my color wheel is shot as well, I am going to take the tv apart today and attempt to fix the color wheel as i have no intention of dumping more money into this dinosaur of a tv. There is only two moving parts on the color wheel, the motor and the wheel it self which is house on a bearing. i'm going to lubricate the bearing and see if that will at all help as i have heard from samsung techs that the main problem with the color wheel is the insufficient dust barrier as well as cheap bearings used. You would think that after spending 2500.00 dollars it will perform at least more then a year

Re: Samsung lcd tv
You have a defective color wheel. Its not easy to change. You must be familiar with the Lite engine. This TV carries 2 types of Color wheel. Look at the side of the TV for your version number to see which one it uses. (1) Part number BP96-00674A COLOR WHEEL (FOR TYPE L3 VERSION PW03 UNITS) (2) Part number BP96-01103A COLOR WHEEL FOR TYPE L6 VERSION PU01 UNITS

no and yes the lamp warning is to alert you that a timer has expired that clocks the approximated life of the lamp in "hours of use". it is never accurate and is dependent on whether or not it was reset the last time a lamp was replaced. reset the lamp timer in the users "setup" menu.
the lamp has NOTHING to do with color, it only provides light.
check the connections between the TV and cable/satelite box...the red.green.blue component connector...the red one is likely loose. if this does not correct you color problem, your optical engine has failed. very expensive repair, not for the DIY type guy.
90% of the time the lamp is bad when the lamp is bad a lot of the time you will here a buzz sound by the lamp its trying to trun on the lamp but cant. also look at the flashing lites on the front of the tv it should give you code
Rulds2008 is probably right. I had the same problem, but have no TV repair shop near me. So since I have experience fixing computers, I decided to repair the TV myself. I initially repaired the Lamp, but the TV still flashed all three lights. Called Samsung and they told me that I might need to replace the ballast, but it would be best to bring it to a repair shop. The repair shop offered to come out and look at it for $150 or bring it in for $120, even though they were about 30 mins away. Ordered both parts on www.Samsungparts.com and got them in three days. Still had the three flashing lights. Took apart the entire TV (googled it on youtube) and vacuumed and dusted the TV and took apart the color wheel (about 20-30 mins). It was completed busted. Found out that if the color wheel is broken, it will not send a signal to the ballast to tell it to start up and power the lamp. So if you have replaced the lamp and/ or the ballast and it does not light up, it is more than likely that it is your color wheel (buy it on ebay or amazon, got it in three days versus a 3-4 week back order on company sites). Also, make sure the power switch on back is being pushed upwards and not downwards or the TV also will not start. Total parts cost me ($400) versus having someone else fix it and charge me double with labor and parts. TV is better than ever. Hope this helps.
Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.
Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.
Pull the front cover off at the bottom. You will see a panel which has to be removed using a screw driver. Inside you will see the lamp assembly. It is a removable box. The lamp can be changed out by just changing out the connections on the new lamp. Before you pull it though try reducing your picture size to 4:3 it helped us to get a little more life out of our lamp.
Take the door back off and look for a safety tab somewhere on the door that will activate a small safety switch, the tab will stick out. Maybe you broke the tab off or just didnt get the door on correctly. Try that and let me know.
You will need to have it diagnosed if you do not have the service manual, or the knowledge of how these circuits work. I can tell you to replace this or that but it would be a guess! You need to start measuring the voltages on the ballast circuit, as I have seen door switches, fan sensors, heat sensors cause all of your symptoms as well. Good Luck
