Question about Samsung HLN4365W 43" Rear Projection HDTV-Ready Television
No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and rechecking every cable and plug you can find.

It could be the color wheel and in fact probably is. I've seen them shatter which would explain the noise. They are glass and spinn at 9000 rpm. An involved repair though definatley a job for a pro. It could be worse, probably a few hundred will do it. Was the TV begining to be a little loud before the failure? Could be a sign, i've seen many noisy color wheels.

SOURCE: No picture, new lamp
Did you reset the hours on the lamp with the menu options on your set? Sometimes, if you do not do that it can mess with the tv performance thinking that its over hours. It needs to be reset to 0 again...

if the picture is still visible but lacking color, it is not the lamp. check the color wheel and make sure it is working. replacing the color wheel is a pretty easy task and can be performed by yourself without many problems. as a sidenote, older samsung dlp tvs seem to experience this problem quite often, although they usually sound like someone strangling a cat before the bearings go out..
partstore.com should carry your replacement for 100 USD or so, the part number is BP96-00250A.
before replacing it, make sure your old one isn't just stuck or not spinning at full rpm, if this is the case, you can usually remove it and clean the motor using electronic or contact cleaner that is safe for plastics.
to check everything out, you will need to remove the back panel of your tv, then power it up (keep kids, small animals, hands and such away from the back while powered up), take a look in front of the projection lamp and see if the wheel is turning. if not, a very good writeup is available here, this is the writeup i send my own customers to if they feel like attempting the repair themselves.
replacing the color wheel is actually not very hard at all, if you have ever worked on your own desktop pc (installed a new drive or upgraded it yourself) then you should be able to do this with limited difficulty.
hope this helps,

all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP

We have the same DLP set and had the same problem. The Color Wheel, P/N BP96-00250A, a $200 part needs replacement to eliminate your problem.
