Mitsubishi dlp tv won't turn on


My family's house once had a older model Mitsubishi DLP TV that went out (which I found out they are famous for). The problem was the projector bulb had died. Your problem is either that or a ballast problem (something more complicated that I do not know how to solve).

Open up the bulb housing on the back of your TV and check to see the condition of your current bulb. NOTE: the bulb housing contains mercury so handle with care. Also, if the bulb is broken/dead, there might be shattered glass sitting inside the bulb housing.

The only way to fix it was to buy a new bulb (search amazon for wd-65837 lamp" you will find a few results). This temporarily fixed our problem. However, for some reason, the aftermarket bulbs do not last anywhere near as long as the original one. So if you do end up buying a replacement bulb, buy something with a good warranty. If this doesn't work just send the bulb back.

Hope this helps!

Replace bulb in lg dlp projection tv and tv won't come on


Presuming bulb was installed correctly it could be the ballast that powers it.

If possible try to look from outside where lamp is to see if it even fires up for a few seconds.

SAMSUNG DLP SLIM 50" AFTER I TURN IT OFF IT WONT TURN BACK ON TILL 30 TO 50 MINS LATER THE THREE LIGHTS IN THE FRONT BLINK. iT ACTS LIKE ITS GONA TURN ON BUT IT DOESNT IT JUST MAKES THE NOISE AND FLASHING...


Chris,

I had the same problem. I bought my tv at Best Buy and my warranty included a new bulb for the lamp. They only last about 2 yrs or so depending on how much you watch the tv. You can also buy replacement bulbs online that don't cost too much. BUT, you will need to replace every couple of years. The things you listed are exactly what happens when the bulb goes out. Hope this helps!

Samsung DLP R&R Color wheel Model #HLR5078w


Samsung's digital light projection (DLP) televisions use a spinning color wheel to create the colors that are seen on the screen. If the color wheel becomes misaligned during use, it will become damaged and have to be replaced. Replacing the color wheel on a Samsung DLP television can be done at home, once a compatible-sized color wheel has been bought from a TV supply store.Replacing the color wheel yourself will void any Samsung warranty that might be in place, but is the only solution for getting the TV working again in as short a time as possible.
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the Samsung DLP TV. Turn the Samsung around so that the back is facing you. Make sure the Samsung is unplugged from the AC socket.
2
Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
3
Loosen the two screws from each side of the projection bulb's case. Pull the projection bulb out. Put the projection bulb aside. Use the Phillips screwdriver to remove the two screws from the left side panel. Pull the side panel and the circuit board attached to it out carefully and put it down so that the cables attached to it have not been pulled out.
4
Take a picture of the power cable's position with the digital camera so that you can put it back correctly later. Pull the power cable out from inside of the Samsung's case so that the center panel is free to be pulled out. Remove the two large headed screws from the center panel with the Phillips screwdriver. Remove the top two screws holding the panel to the plastic case using the Phillips screwdriver.
5
Slowly slide the center unit out a few inches. Take a picture of the projector lens' positioning with the digital camera so that you can put it back correctly later. Unplug the two cables from the left side of the center panel. Unscrew the sensor switch using the Phillips screwdriver. Slide the center panel completely out of the Samsung and put it down on the clean cloth. Blow off the color wheel assembly with the compressed air.
6
Use the tweezers to remove the green plug from the top of the color wheel cover. Use the tweezers to remove the two cables at the side that are coming from the color wheel. Use the Phillips jeweler's screwdriver to remove the screws from the top, front and back of the color wheel cover. Slide the color wheel cover straight up to expose the color wheel.
7
Use the Phillips screwdriver to remove the three screws holding the color wheel to the color wheel assembly. Lift the color wheel up and out of the color wheel assembly and discard it.
8
Position the replacement color wheel in the color wheel assembly. Reassemble the color wheel and reassemble the color wheel assembly. Put the color wheel assembly back into position in the rear of the Samsung DLP TV. Reassemble the Samsung DLP TV. Plug the Samsung DLP TV back in for power. Turn the Samsung on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.

MY TV TURNS ON AND STAYS ON FOR 5SECONDS AND THEN THE SCREEN TURNS BLACK BUT CAN STILL HEAR THE SHOW PLAYING. TURNED IT OFF AND EVEN UNPLUGGED IT FOR ABOUT 5 MINUTES, BUT STILL THE SAME THING HAPPENS.


the lamp is likely bad .. they only work a few thousand hours .. then must be replaced .. your lamp can cost a couple of hundred (maybe even more if bought locally) .. here is one for less if you have someone handy that can change it.......
http://www.purelandsupply.com/50PL9126D-37-Bulb-Philips-DLP-TV-Bulbs.html
..... of course make sure power is off (unplugged) and make sure things are not hot .. there is usually a little cubby in the back where the lamp is located .. you an see what the lamp looks like at the above URL .. dont get finger prints on the bulb . that will cause it to crack when hot .. if you are unable to change the bulb then a call to philips service should do the trick. make sure you ask what the bulb replacement and labor will cost ..

Describe how to replace bulb for magnavox hdtv #50ml6200d37


easy. pop off the front cover.. Start at the right edge. The front part that covers the speakers comes off as a complete cover. Then there is a square panel that must be removed on the left side front about three screws. once the panel is off there is three thumb screws .. loosen them.. they do not come out. then when they are loose pull on the panel handle and out comes the bulb unit. then follow the install instructions of the new bulb. Do not touch the bulb with your hands... It goes back the same way .. The exterior panel must be in place for the tv bulb to fire up..

Samsung Dlp completely shuts off and then all three lights flash


Sounds more like the TV is overheating. The lamp cooling fan may be seized or not spinning fast enough. If the TV gets hot enough to trip the thermal, it could rupture the lamp.

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.
