There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

Hi,sounds like you might be experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Your part # is BP96-00250A You can find it here http://www.discount-merchant.com/Samsung-BP96-00250A-ColorWheel-Assembly-p/bp96-00250a-color-wheel.htm?Click=48173 and here's the instructions to replace it : http://www.fixyourdlp.com/guides/samsung/bp96-01579a.php Have a bless one!

That sounds like one of 2 things:

1. Color wheel
2. Light engine

Color wheel because of the losing color, but the light engine because of the picture freeze. It's very difficult to judge since I can't be there to see it. I'm leaning toward the light engine though. The only fix is to replace the DMD board, or entire light engine.

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Sounds like the color wheel may have also gone bad. I recently saw a 56" Samsung where the bulb and color wheel went at the same time. The color wheel could produce a crying noise while trying to spin up.

Your bulb is burned out. I have had the same problem. It seems this television has an overheating problem--and short bulb life. I have had our 50 Magnavox dlp for two years and just put in the second bulb before Christmas. You can buy the bulb from a dealer on ebay for $99 and install it yourself. I is not in the housing so you have to carefully take out 4 screws and replace the bulb without touching the face of the bulb. To buy the one from Magnavox with the housing is much more expensive. I think the first time my husband replaced the bulb it took about 45 minutes--this time it took about 20.

check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.

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

possible color wheel is faulty,call a service shop for an estimate of cost.
