Ok this is kinda funny...erk..uhh the reason there was no power was that i had failed to notice there was a safety switch in the lamp access door. if the door is open there is no power so make sure if you are working on it to close the door before trying to power up!!

I have an rca hdlp6iw51 and i found a color wheel on ebay but i dont know how to change it does anyone have any advice


Follow this steps:
1. Take the back panel off of your set, using your Phillips head screwdriver, to remove any screws. 2. Remove the projector lamp. You can reach the color wheel without doing it, but you are less likely to damage the projector lamp if you take it out. Loosen the screws at the base: depending on your DLP's brand, the screws may come out, or may just loosen. If they come out, set them in a safe place before removing the lamp. If not, just pull the entire lamp out, once the screws will not loosen further. 3. Take out the panel that is connected to the cable outlets, using the screwdriver to take out any screws. Pull the panel until the cables, attached from the inside, run out of slack.
4. Remove the screws at the bottom of the panel, in the center, and any screws connecting this panel to the outer case of your DLP. The number and location of these screws will vary depending on your DLP's brand.

  • 6 Pull out the entire center unit, pulling gradually. Then, unplug the power cable from the main set (this is generally blue and brown). Remove the sensor switch and any cables joining the center unit to either side of the set.
  • 7 Take out the plug from the cover of the color wheel. In most brands, it will have a black and blue wire connected to a green circuit board. Then, remove any cables coming out of the wheel. Depending on the brand, the screws may be small enough to require the jeweler's screwdriver.
  • 8 Remove the screws holding the color wheel cover in place. Remove the cover, then take out the screws holding the wheel in place. If tape is holding the wheel, just pull on the wheel until it comes free.
  • 9 Put the new wheel into the slot. You do not want to touch the wheel, or you will blemish it and leave impressions that will be visible when the light shines through it. Re-insert the screws. Then, replace the cover, making sure that the wire jacks are in the same places.
  • 10 Reassemble the DLP television, then plug the set into the wall, and turn on the power.

    you either need another Lamp which is very possible or Ballast Board. Ballast board is what turns Lamp on, pull back watch to see if there is a Ark coming from spark cap on Ballast board if so Lamp if not Ballast board call Mats for lamp 1-800-628-1118 OR Go to E-Bay for Lamp and Ballast Board Look under TV Parts After rereading your Post I think Lamp! Samsung OEM Had Alot of defective Lamps and do not hold up!

    Lamp went out on DLP TV


    Did you replace the lamp door? A flashing red light is an indication of a door open or an impropely seated lamp. Try removing the lamp and reseating it. Reinstall the door and try turning it on again. Also, you may want to unplug the TV from the power source, count to about 20 and then plug it back up again. This may reset the TV.
    Good luck
