Sounds like the DM3 isnt powering up the ballast to light the lamp or the ballast may be faulty. i would suggest trouble shooting the DM and ballast voltages.

Power button blinks green about 1 minute then goes red


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if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

Loud humming sound on with a purplish and pinkish screen on my 50 inch dlp samsung, 5 yrs old.


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.

Samsung 50" DLP - Lamp Light Blinking after bulb replacement


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.

New problem... replaced color wheel and lamp still won't work


This set has had issues with the power supply. It may have defective capacitors. This would require disassembly and replacement of parts.

Do you have test equipment and a service manual?

If you have a repair shop
do the repair, your cost may be $300.00- $400.00 to repair.

Parts and manuals can be purchased at:

Magnavox 50" DLP Tv power light comes on but then i hear a buzzing noise and then two red lights come on the tv. at no point does the picture turn on during this time. Can you please give me a possible...


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.

Akai PT50DL24 50 in DLP Rear Projection TV-NO PIC OR SOUND


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.
